Moving Object Recognition and Detection Using Background Subtraction

Motion detection and object recognition algorithms are a significant research area in computer vision and involve building blocks of numerous high-level methods in video scrutiny. In this paper, a methodology to identify a moving object with the use of a motion-based segmentation algorithm, i.e. background subtraction, is explained. First, take a video as an input and to extract the foreground from the background apply a Gaussian mixture model. Then apply morphological operations to enhance the quality of the video because during capture the quality of a video is degraded due to environmental conditions and other factors. Along with this, a Kalman filter is used to detect and recognize the object. Finally, vehicle counting is complete. This method produces a better result for object recognition and detection.

Proposal of Linear Specific Functions for R-L-C as Fundamental Elements in Terms of Considered Specific Electric Constants

In this paper electric physical quantities which can be characterized as being of either of the scalar or phasor type, are discussed. The scalar physicalities of resistance, inductance and capacitance are regarded as being of a fundamental type as they provide the initial basis of circuit designing, while the phasor physicalities are voltage and current etc. These fundamental elements may also be regarded as conventional in comparison to those of semiconductors devices, which are introduced later. In taking these scalar elements into consideration, the linearized specific functions are consider in terms of the considered specific electric constants possible from the ground of already existing electromagnetic constants of the wave propagating through the free space, namely intrinsic impedance, permeability, and permittivity.

Efficient Video Delivery Over a Software-Defined Network

This paper proposes a framework called SDN Streamer for an OpenFlow controller in order to provide QoS support for scalable video streaming over an OpenFlow network. OpenFlow is a protocol that decouples control and forwarding layers of routing. Abstracting control from the forwarding plane lets administrators dynamically adjust network-wide traffic flow and keeps the network agile. Software-Defined Networking (SDN) aims to improve the reliability of multimedia streaming while reducing utilization of server resources. It optimizes video delivery using a Scalable Video Coding (SVC) algorithm that sends layers of different quality via discrete paths. Dynamic rerouting capability is ensured using a Lagrange Relaxation-based Aggregate Cost (LARAC) algorithm. Unlike Dijikstra’s algorithm, the LARAC algorithm does not calculate least “hop-counts” to find the optimal path but calculates the optimal path based on “link statistics.” The SDN Streamer can guarantee seamless video delivery with little or no video artifacts experienced by the end-users. This project makes use of HTML5 for browser display. The SDN server allows everyone to access the media files irrespective of their platform, device or browser. Performance analysis shows there is significant improvement on the video’s overall PSNR under network congestion.

A Viewpoint: Discrimination Between Two Equivalent Statements of Kirchhoff’s Current Law from the Ground of Precedenceness

In this paper, on the ground of precedenceness, the two equivalent statements in regard to the basic law of electrical from Kirchhoff’s current are discriminated. Here, this viewpoint of statements discrimination for the law of same does not means to regard that there is a differences in between, but to regard that the statement of one out of the two exist due to the existence of other. In addition, the current regulation function is discussed, which is always limited to the range of 0 to 1 as it determines the ratio of totality at each node for either sides of the branches collected by the converger and diverger respectively. In the case of a condition without unity, it determines that the law of conservation of charge does not hold.

A DES-Based Mechanism to Secure Personal Data on the Internet of Things

The Internet of Things (IoT) helps users in their day to day activities such that they can communicate with each other through sensors very easily and in less time. Communication through intermediate sensor nodes may violate security because it may harm confidential user data or information by either modifying it or not forwarding to it. To deal with such problems, a number of cryptographic secure mechanisms are available that provide symmetric and asymmetric keys to secure data and each mechanism has its own pros and cons. In this paper, a secure DES-based mechanism is proposed in which a DES algorithm is used to transfer the data between users through sensor nodes without no loss of security.

A Reputation-Based Mechanism to Detect Selfish Nodes in DTNs

A delay tolerant network (DTN) is a complete wireless network. In a DTN there is no base station as it is in the case of existing wireless networks. Nodes may behave selfishly to transmit a message to save their own resources, such as energy. The cooperation requires detecting routes and transmitting the packets for other nodes, even though it consumes network bandwidth, buffer, and energy. A selfish node is a node that may be unwilling to cooperate to transfer packets. Such a node wants to preserve its own energy while using the services of others and consuming their resources. Many approaches have been used in the literature to implement the concept of non-cooperation in a simulated environment. However, none of them is capable of reflecting real cases and thus, the implementation of non-cooperative behavior needs improvement. In this paper, we focus on malicious and selfish node behavior, and we present a new classification and comparison between existing methods and algorithms to implement selfish nodes. Finally, we propose a new algorithm to implement selfish nodes in a DTN environment.

Improved Target Detection in Doppler Tolerant Radar Using a Modified Hex Coding Technique

In every corner of the globe, nations want to improve the monitoring mechanism of the country, so that no one can enter their territory in an unwanted manner easily. Well-known equipment, called Radar, is commonly used for monitoring. However, only a small amount of work is done to monitor multiple moving targets in the presence of Doppler. This important issue diverts the attention of the research community away from working on this platform. In the present literature, the merit factor (MF) is improved by increasing the amplitude of the main lobe. However, these particular approaches did not attach more importance to the effects of noise side peaks of fast moving targets. The drawback of noise peaks masks slow-moving targets and cannot be clearly seen by the radar receiver. As a result it reduces the performance of the Doppler radar system. In this paper, an approach is presented which not only improves multiple moving target detection, but also reduces the energy of code generation. This approach is simple and effective in detecting multiple moving targets at the desired Doppler. The presented technique is called Improved Target Detection in Doppler Tolerant Radar Using a Modified Hex Coding Technique. MATLAB is used to formalize the results by simulation.

Enhanced Packet Loss Calculation in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are autonomous and structure-less dynamic networks which consist of spatially distributed sensor nodes to support real-time applications. However, due to limited resource availability these networks face certain challenges. Many researchers address bandwidth and delay using different approaches to increase the quality of service (QoS). Almost all researchers address loss calculation using sliding window flow control protocol, which may not always give an optimum solution. So, accurate loss calculation is necessary to increase the packet delivery ratio (PDR) which in turn increases QoS. In this paper, a mathematical model is proposed to enhance the loss calculation in WSNs using Poisson theory.

Enhanced Security of MANETs Against Black Hole Attacks Using AS Technique

A mobile ad hoc network (MANET) is an autonomous structureless arrangement of mobile nodes to figure a momentary network. Communication between any two nodes is possible directly if the two nodes belong to the same sensing range; otherwise communication can be achieved by means of the nodes which are present between source and destination. As the network nodes are mobile, any node can enter or leave the network at any particular time interval. Thus, whichever node is present in between the source and destination can perform as a router or the host node in the arranged network. Therefore this poses security challenges to MANETs. This paper presents a solution to black hole attacks. The presented method is easy to use and efficient in detecting black hole attacks. The presented approach is validated by the use of network simulator 2 (NS2).

Design of a Smart Water-Saving Irrigation System for Agriculture Based on a Wireless Sensor Network for Better Crop Yield

Precision agriculture is a decision-support system that helps farmers to make better decisions in the management of their farms, thus increasing returns while preserving resources. An automated irrigation system facilitates continuous and efficient irrigation under conditions of water and labor scarcity. Overwatering of crops causes nutrients to flow off the land surface and this can lead to lower crop yields. This wireless technology helps farmers to address the problem of overwatering and underwatering their crops. Currently, automation is one of the more important aspects affecting human life. It not only provides comfort but also reduces energy, increases efficiency and saves time. The proposed system uses wireless technology to irrigate crops in need of water. Water requirement varies depending on the type of crop, for example, paddyfields needs more water while crops like ragi needs less water. The proposed system irrigates based on the water requirements of particular crops in particular areas and the system as designed also provides smart irrigation technology at a low cost, usable by Indian farmers. Temperature, humidity, moisture of the land, and the water level in the tank will be measured and sent to the user via GSM communication. The water pump is automatically operated through the messages and Android application. Data is stored in the cloud for analysis. The proposed moisture-sensing method has the ability to be incorporated into an automated drip irrigation scheme and perform automated, precision agriculture in conjunction with decentralized water control.

SVM—A Way to Measure the Trust Ability of a Cloud Service Based on Rank

Trust management is one of the most serious and demanding issues facing by cloud computing. In spite of having some surprising qualities, such as virtualization potential, highly optimized storage capacity, multi-tenancy features, and 24-7 service availability, cloud technology still faces security and authenticity issues, which have created an obstacle for adapting cloud computing as a widespread technology. Threat is a qualitative factor rather than its quantitative approach. Trust is also a quality factor, which can be more useful when trust can be established and proven quantitatively. Previously, cloud users had to show blind faith towards cloud service providers and vendors. Today, the importance of cloud auditing has increased. This paper focuses on the establishment of trust and measuring the quality of service for SaaS cloud service model, by using some measurement indices and with the help of some known parameters.

An Optimized Five-Layer Model with Rainfall Effects for Wireless Propagation in Forests

This paper presents a new propagation model for evaluating the fading of wireless communication signals in forests. The model considers rainfall and snowfall effects, and allows for the estimation of attenuation at varying frequencies in the VHF/UHF bands that are used by cognitive radios. The structure of the vegetation environment is represented here by five material layers, namely soil, scrubs and small plants under the trees, trunks of trees, foliage of trees, and free space. The model parameters are optimized using the least squares technique. The resulting model is verified by comparison with measured data where acceptable agreement is observed. The average rain rate R0.01% that will probably be exceeded for at most 0.01% of the year is computed using real measured data in Jordan. R0.01% is found to be 22.9 mm/h which agrees with the ITU recommended value of 22 mm/h.

Leak Detection Methods—A Technical Review

For safe transmission of various fluids or gases leakage detection in pipelines is very important. The leak of hazardous/dangerous fluids and gases can cause loss of property and lives (e.g., the Bhopal gas tragedy). Hence review of various available technologies should be necessary in order to identify a technology which provides an easy, adaptable, flexible, inexpensive, and efficient approach for real-time distributed data acquisition and monitoring. Based on review one can able to know that which technology has a very low false alarm rate and cost effective one etc. In this paper the performance and ability of the different systems is compared in terms of their leak detection capability.

Text Message Classification Using Supervised Machine Learning Algorithms

In recent years, as the popularity of mobile phone devices has increased, the short message service (SMS) has grown into a multi-billion dollar industry. At the same time, a reduction in the cost of messaging services has resulted in the growth of unsolicited messages, known as spam, one of the major problems that not only causes financial damage to organizations but is also very annoying for those who receive them. Findings: Thus, the increasing volume of such unsolicited messages has generated the need to classify and block them. Although humans have the cognitive ability to readily identify a message as spam, doing so remains an uphill task for computers. Objectives: This is where machine learning comes in handy by offering a data-driven and statistical method for designing algorithms that can help computer systems identify an SMS as a desirable message (HAM) or as junk (SPAM). But the lack of real databases for SMS spam, limited features and the informal language of the body of the text are probable factors that may have caused existing SMS filtering algorithms to underperform when classifying text messages. Methods/Statistical Analysis: In this paper, a corpus of real SMS texts made available by the University of California, Irvine (UCI) Machine Learning Repository has been leveraged and a weighting method based on the ability of individual words (present in the corpus) to point towards different target classes (HAM or SPAM) has been applied to classify new SMSs as SPAM and HAM. Additionally, different supervised machine learning algorithms such as support vector machine, k-nearest neighbours, and random forest have been compared on the basis of their performance in the classification of SMSs. Applications/Improvements: The results of this comparison are shown at the end of the paper along with the desktop application for the same which helps in classification of SPAM and HAM. This is also developed and executed in python.

Error Assessment of Fundamental Matrix Parameters

Stereo image matching comprises of establishing epipolar geometry based on fundamental matrix estimation. Accuracy of the epipoles is governed by the fundamental matrix. A stereo image pair may contain errors on a systematic and/or random basis which determine the accuracy of the fundamental matrix required for matching. The algorithm used to extract the image pair correspondence, and the method used to estimate the correct parameters of the matrix, controls its accuracy further. A performance analysis of widely adopted matrix estimators over the point pairs found by correspondence determiners is undertaken in this chapter. The methods are modified for the best combination of results, based on the properties of the resulting fundamental matrix. Permutations are analyzed over the possible paths for obtaining the matrix parameters with the expected characteristics, followed by error analysis. Amongst the estimators analyzed, RAndom SAmple Consensus (RANSAC) and M-estimator SAmple Consensus (MSAC) estimators were found to produce the best results over the features detected by the Harris–Stephens corner detector.

A Two-Band Convolutional Neural Network for Satellite Image Classification

The advent of neural networks has led to the development of image classification algorithms that are applied to different fields. In order to recover the vital spatial factor parameters, for example, land cover and land utilization, image grouping is most important in remote sensing. Recently, benchmark classification accuracy was achieved using convolutional neural networks (CNNs) for land cover classification. The most well-known tool which indicates the presence of green vegetation from multispectral pictures is the Normalized Difference Vegetation Index (NDVI). This chaper utilizes the success of the NDVI for effective classification of a new satellite dataset, SAT-4, where the classes involved are types of vegetation. As NDVI calculations require only two bands of information, it takes advantage of both RED- and NIR-band information to classify different land cover. The number and size of filters affect the number of parameters in convolutional networks. Restricting the aggregate number of trainable parameters reduces the complexity of the function and accordingly decreases overfitting. The ConvNet Architecture with two band information, along with a reduced number of filters, was trained, and high-level features obtained from a tested model managed to classify different land cover classes in the dataset. The proposed architecture, results in the total reduction of trainable parameters, while retaining high accuracy, when compared with existing architecture, which uses four bands.

Dimensionally Reduced Features for Hyperspectral Image Classification Using Deep Learning

Hyperspectral images (HSIs) cover a wide range of spectral bands in the electromagnetic spectrum with a very finite interval, and with high spectral resolution of data. The main challenges encountered with HSIs are those associated with their large dimensions. To overcome these challenges we need a healthy classification technique, and we need to be able to extract required features. This chapter analyzes the effect of dimensionality reduction on vectorized convolution neural networks (VCNNs) for HSI classification. A VCNN is a recently introduced deep-learning architecture for HSI classification. To analyze the effect of dimensionality reduction (DR) on VCNN, the network is trained with dimensionally reduced hyperspectral data. The network is tuned in accordance with the learning rate and number of iterations. The effect of a VCNN is analyzed by computing overall accuracy, classification accuracy, and the total number of trainable parameters required before and after DR. The reduction technique used is dynamic mode decomposition (DMD), which is capable of selecting most informative bands using the concept of eigenvalues. Through this DR technique for HSI classification using a VCNN, comparable classification accuracy is obtained using the reduced feature dimension and a lesser number of VCNN trainable parameters.

Asymptotic Symbol Error Rate Analysis of Weibull/Shadowed Composite Fading Channel

In this work, we derive the asymptotic expressions of the average symbol error probability (SEP) of a wireless system over the Weibull-lognormal fading channel. First, we evaluate an approximation of the multipath distribution at the origin then the composite distribution is obtained by averaging the approximate multipath probability density function (PDF) with respect to shadowing. The result is further extended to include maximal ratio combining (MRC), equal gain combining (EGC), and selection combining (SC) PDF at the origin. The derived expressions of the composite PDF are further utilized to evaluate the average SEP for both coherent and non-coherent modulation schemes. The derived expressions have been corroborated with Monte-Carlo simulations.

In this paper a typical waveguide in 2D photonic crystal of air holes in dielectric slab structure has been simulated to explore the possible transmission spectrum as shown later in various figures. The waveguide width is variable and correspondingly its transmission spectrum changes. This may be improved upon and used to design optical communication devices and photonic sensors. The algorithms used for simulation are finite difference time domain (FDTD), and plane wave expansion method (PWEM).

Minimization of the Size of an Antipodal Vivaldi Antenna for Wi-MAX and WLAN Applications

In this paper, miniaturization of the antipodal Vivaldi antenna is discussed. The antipodal Vivaldi antenna is a broadband antenna and thus it is suitable for use in many wireless applications. The proposed antenna has a center frequency at 3.6, 5.2, and 5.8 GHz and so it can be used in WiMAX as well as WLAN systems and to avoid potential interference from narrowband communication systems, it is advised to design a miniaturized broadband antenna with intrinsic band-notched characteristics which can be used in narrowband communication. The circular slots are applied on the edge at the width of the Vivaldi antenna and are etched properly and as a result this helps in the area minimization of the antenna. The circular slot with the greatest diameter is used to achieve the different center frequencies so that the proposed antenna can be used for wireless communication, i.e. for WiMAX and WLAN. The rectangles are used on the alternative circular slots so as it can be used as notched structure and the interference in between the two different wireless applications can be minimized. The bandwidth of the proposed antenna is 2.8–6.2 GHz. A comparison of a conventional Vivaldi antenna with an antipodal antenna is also undertaken. The simulation of the proposed antenna was performed using HFSS13.0 software. The return loss, gain, radiation pattern, z-parameters, and VSWR are shown.

Physical Layer Impairment (PLI) Aware Lightpath Selection in WDM/DWDM Networks

The demand for high data rate with low bit error rate (BER) and large bandwidth is highly satisfied in wavelength division multiplexing/dense wavelength division multiplexing (WDM/DWDM) networks. However, the signal traveling inside the optical fiber can be affected by various physical layer impairments (PLIs). These impairments are caused due to fiber non-linearities and the non-ideal nature of optical components. Dispersion is one of the PLI constraint which affects signal quality. That needs to be compensated. This research work presents the approach of dispersion penalty (DP). It also suggests a PLI-aware lightpath selection algorithm based on DP.

Miniaturized MIMO Wideband Antenna with L-Shaped DGS for Wireless Communication

In this paper, a MIMO antenna is designed consisting of two planar symmetrical monopole antennas and the ground plane is slotted into L-shaped. The simulation results indicate that the antenna works well in the ultra-wide band and hence can be used in a wide range of applications. The return loss is below −62 dB at 7.1 GHz and below −32 dB at 3 GHz approximately, which is highly desirable. This antenna has a wide frequency range of 2.4–10 GHz. The overall antenna size is as low as 35 mm × 22 mm but the effect of the mutual coupling among the antenna elements is reduced and is below −10 dB over a wide range of frequencies, i.e. 2.4–8 GHz. Reducing the effect of mutual coupling is a challenge in MIMO antennas, and has been achieved in this case. The maximum gain achieved is approximately 2.2 dB. The design has been simulated using Ansoft HFSS software. The attributes of S-parameters, VSWR, gain, radiation pattern, and Smith chart are shown and its applications are discussed.

An Enhanced Reputation-Based Data Forwarding Mechanism for VANETs

A vehicular ad hoc network (VANET) is a self-configuring and infrastructureless network connecting high mobility random vehicles by wireless links. Due to high mobility, data transmission between two vehicles may possible through other intermediate vehicles but it is difficult to transmit messages through these intermediate vehicles because intermediate vehicles may violate security by sending the wrong messages or by not forwarding messages. So transmission of messages using trust-based VANETs is a difficult task. Various techniques are proposed by researchers to forward packets in trust-based VANETs. Each technique has its own mechanism as well as its pros and cons. In this paper we propose an enhanced trust-based mechanism to select trusted nodes through which messages are transmitted. The proposed mechanism has been implemented using ONE (opportunistic network environment) simulator. Results shows that the proposed mechanism has a high delivery ratio and less message delay than existing reputation-based mechanisms.

Statistical Metric Measurement Approach for Hazy Images

A novel statistical metric measurement approach for the evaluation of enhancement of hazy images. Metric measurement plays a critical role in picture enhancement in hazy weather conditions and leads to a lessening in pixel resolution, a distortion in color, and gray images. In this paper hazy and foggy images are considered for evaluation using contrast-to-noise ratio (CNR) which dehazes the original hazy images. We propose a unique novel effective parameter based on an image filtering approach. The results demonstrated show a better CNR for dehazed images.

Image Enhancement for Fingerprint Recognition Using Otsu’s Method

The internal surfaces of human hands and feet of have minute ridges with furrows between each ridge. Fingerprints have very distinctive features and have been used over a long period of time for the identification of individuals and are now considered to be a very good authentication system for biometric identification. For successful authentication of fingerprint, features must be extracted properly. The different types of fingerprint enhancement algorithms used in image processing all provide different performance results depending on external and internal conditions. External conditions include types of sensors and pressure applied by the subject etc. Internal conditions include the body temperature of a subject and skin quality etc. In this paper, we enhance an image using Otsu’s method, which is one of the segmentation steps of image processing. This algorithm can improve the clarity of ridges and furrows of a fingerprint and enhances performance by reducing the total time for extraction of minutiae compare to other algorithms.

Estimation of Success Probability in Cognitive Radio Networks

In this paper, we considered a cooperative spectrum sensing over fading and non-fading channels. We proposed a model of a Rayleigh fading channel and a non-fading additive white Gaussian noise channel. Total error rates and the optimal number of cooperative secondary users over the non-fading channel and the success probability over the fading channel are calculated and the simulation results plotted. The simulation results convey that the optimal number of secondary users is five in both cases. We hope that our results will be useful in improving energy efficiency in identifying the unutilized spectrum.

Analysis of Road Accidents Through Data Mining

There is currently a great deal of interest relating to road accidents that result in the loss of life or harm to an individual. GIS is capable of storing information regarding road accidents like vehicle accidents, hour wise accidents, day wise accidents. Apart from this, road accidents are also addressed by road traffic database. In this research on the city of Hyderabad, road traffic databases is taken into considerations where road accidents impact on the socioeconomic growth of society. A data mining technique is used to discover hidden information from the warehouse to handle road accident analysis. We implement algorithms, such as prediction and classification in Weka version 3.7. We use k-Madrid to form a cluster of related information. Different attributes are subjected to analysis with the conclusion that prediction is the most suitable and accurate algorithm.

Bearing Fault Detection and Classification Using ANC-Based Filtered Vibration Signal

The defective bearing in a rotating machine may affect its performance and hence reduce its efficiency. So the monitoring of bearing health and its fault diagnosis is essential. A vibration signature is one of the measuring parameters for fault detection. However, this vibration signature may get corrupted with noise. As a result this noise must be removed from the actual vibration signature before its analysis to detect and diagnose the fault. ANC (adaptive noise control)-based filtering techniques are used for this noise removal and hence to improve the SNR (signal-to-noise ratio). In our study an experimental setup is developed and then the proposed work is executed in three stages. In the first stage the vibration signatures are acquired and then ANC is implemented to remove the background noise. In the second stage the time (statistical) and the frequency analysis of the filtered vibration signals are done to detect the fault. In the third stage the statistical parameters of the vibration signatures are used for the classification of the fault present in the bearing using random forest and J48 classifiers.

A New Approach to Securing Online Transactions—The Smart Wallet

For many years, two-factor authentication has been the only means of preventing cyber attacks and providing cyber security to online transactions. However, it seems to be vulnerable due to weak spots through which hackers are able to easily find ways of either intercepting message codes or exploiting account recovery mechanisms. Most of the available systems provide a onetime text password as an SMS to the registered mobile number of the user, while a few of them deliver it via telephone call leaving users to worry about its misuse through their phone being stolen or the SMS being seen by a hacker who can easily hack the SIM network provider and read the message, or by specific calls being diverted to his/another mobile number without the knowledge of the original recipient. The result was a huge detriment to the user, leaving him to worry about his hard-earned money. As a result, we are presenting this Smart Wallet approach.

A Global Dispatcher Load Balancing (GLDB) Approach for a Web Server Cluster

With the volatile expansion of the internet, numerous innovative online applications and services are in development. In conventional internet architecture, the innovative disputes are imposed by the fashionable applications. By using multiple servers, web server performance is improved and the effectiveness of a simulated web server system depends upon the process of distributing client requests. The distribution of client requests must occur in a way that is transparent to users among multiple server nodes, which affects availability and scalability in the distributed web server system. Thus, in this study, an efficient load balancing architecture called global dispatcher-based load balancing (GDLB) is proposed, which uses both domain name system and dispatcher. With this approach, performance is estimated to be better than with existing approaches. To analyze performance, a JMeter testing tool is used for dynamic load generation and performance measurement in a real-life internet scenario.

Automation of Railway Crossing Gates Using LabVIEW

Train accidents at level crossings have always been a concern for the railways. The aim of this paper is to propose an automatic gate system at unmanned level crossings to replace gates operated by gatekeepers. By using this automatic railway gate management system, the arrival of the train is detected by the proximity detector placed with reference to the gate. Hence, the time that the gates are closed is less than with hand-operated gates and the amount of human labor needed is reduced too. This system can be employed at unmanned crossings wherever the probabilities of accidents is high and reliable operation is needed. It provides safety to road users by reducing accidents that occur as a result of carelessness on the part of either road users or gatekeepers. Mistreatment IR sensors and servo motors work automatically to open and shut the gates depending on the presence of train before the crossing. With relevance to the paper that used a single IR sensor to trace the train’s position by employing a controller, we used two IR sensors on either side of the track. And later we programmed them by connecting them to myRIO through National Instruments LabVIEW platform.

Hexagonal Intersection-Based Inner Search to Accelerate Motion Estimation

The computational complexity of motion estimation (ME), increases proportionally with the number of search points. As a result, rapid ME techniques reduce complexity by using different search patterns. Of these techniques, hexagonal search (HS) with a small diamond search pattern (SDSP) significantly reduces complexity compared to other fast ME algorithms. The proposed hexagonal intersection search (HIS) algorithm improves the inner search of HS. The new algorithm cares the inner points near to the intersection of a hexagon rather than a SDSP or a full search. The proposed algorithm reduce 7–15% search points compared with HS. Compared with other popular algorithms, the HIS algorithm made the lowest number of average search points with negotiable PSNR loss.

A Comprehensive Study of 1D and 2D Image Interpolation Techniques

Image interpolation plays an important role in converting a low resolution image into a high resolution image. This paper provides a comprehensive study of perdurable image interpolation techniques, such as nearest neighbor, bilinear, bicubic, cubic spline, and iterative linear interpolation. The usage of a Lagrange polynomial and a piecewise polynomial gives a better fitting curve for interpolated pixel values. The parameters of interest are the signal-to-noise ratio, peak signal-to-noise ratio, mean square error and processing time. Experiment results are used to analyze the performance of interpolation algorithms. These results help us to choose an appropriate algorithm for better usage.

Reinforcement Learning-Based DoS Mitigation in Software Defined Networks

A software defined network (SDN) is an OpenFlow-based network that initiates innovative traffic engineering and also simplifies network maintenance. Network security is still as stringent as that of traditional networks. A denial of service (DoS) attack is a major security issue that makes an entire network’s resources unavailable to its intended users. Blocking the flows based on the number of flows per port threshold was the most common method employed in the past. At some occasions legitimate traffic also takes the huge flow will punish by default rules. In order to address this issue, I proposed a reinforcement learning-based DoS detection model that detects and mitigates huge flows without a decline in normal traffic. An agent periodically monitors and measures network performance. It also rewrites the flow rules dynamically in the case of rule violation.

Design of a Low Power Full Adder with a Two Transistor EX-OR Gate Using Gate Diffusion Input of 90 nm

A full adder is the one of the main parts of an arithmetic logic unit (ALU). In this paper a full adder is developed using gate diffusion input (GDI) to perform fast arithmetic operations. The main aim of this paper is the design of a two transistor XOR gate-based full adder using a gate diffusion input (GDI) technique. A two transistor (2T) EX-OR gate is a suitable gate in the design of a full adder. The intention behind the novel method of a 2T EX-OR gate-based full adder design is to reduce power and improve speed in an optimized area with a lower transistor count compared with CMOS technology. A GDI approach is the one of better methods available for the design of digital logic circuits and tends to run the improved conditions. The proposed technique is then applied to a full adder design. The complete work is carried out using the 90 nm technology of a cadence tool to calculate power, delay, and area for the 2T EX-OR gate. The resulting analysis shows that the proposed method is better than conventional CMOS technology.

Issues in Wireless Sensor Networks with an Emphasis on Security

Wireless sensor networks (WSNs) are spatially dispersed systems with self-configuring sensor nodes connected via a wireless medium. The applications of WSNs are growing exponentially regardless of their known shortcomings. The very first applications of WSNs were military and surveillance based and even now military applications form a major portion of WSN applications. Due to the aforementioned reason and the sensitive nature of the data collected by WSNs, security has become a prime concern. This paper is focused on various issues present in WSNs with a minor emphasis on security.

Evaluation of Selected Tree- and Mesh-Based Routing Protocols

This paper researches various routing protocols, problems and necessities comparatively in MANET routing and layout concerns which include classifications primarily based on layers and other aspects. The layout and implementation of PUMA is a declarative constraint-fixing platform for coverage-based total routing and channel selection in multi-radio wi-fi mesh networks. PUMA integrates a high-performance constraint solver with a declarative networking engine. PUMA achieves a high data delivery ratio with very restricted manage overhead, which is almost constant in a large range of community situations. PUMA uses an unattached manipulate packet format for querying the receivers while ODMR has separate manage packets for querying exclusive manipulate information. The outcomes from a huge range of eventualities of varying mobility, organization members, a wide variety of senders, traffic load, and a wide variety of multicast organizations show that PUMA attains higher packet delivery ratios than ODMRP and MAODV, whilst incurring some distance less manipulate overhead.

Reduction of Kickback Noise in a High-Speed, Low-Power Domino Logic-Based Clocked Regenerative Comparator

The comparator is the most significant element in the design of ADCs. Also there is a lot of demand for low-power, high-speed VLSI circuits. Therefore to maximize power efficiency and speed in ADCs, there is a desire to design high-performance clocked regenerative comparators. The regenerative latch of the comparator is responsible for taking decisions quickly and accurately. Normally, the accuracy of an ADC is degraded due to disturbance in the input voltage called kickback noise, which usually occurs with large variations of voltage at coupled regenerative nodes. This paper describes an analysis of the minimization of kickback noise in a clocked regenerative double tail comparator. To improve further on the double tail comparator, a new domino logic-based regenerative comparator is realized with high speed, low power and reduced kickback noise at low supply voltages. The simulated results using 130 nm CMOS technology confirm the theoretical results. The analysis of the proposed design demonstrates that kickback noise, power, and delay are considerably reduced. The simulation work was carried out using Mentor Graphics tools.

Two-Level Intrusion Detection System in SDN Using Machine Learning

Software Defined Networking (SDN), the new paradigm in network architecture is changing how we design, manage, and operate an entire network, making networks more agile, flexible, and scalable. Such admirable features arise from the design factor that, in SDN, the control plane is decoupled from the data plane and instead resides on a centralized controller that has complete knowledge of the network. As SDN continues to flourish, security in this realm remains a critical issue. An effective intrusion detection system (IDS), which can monitor real-time traffic, detect and also identify the class of attack would greatly help in combating this problem. This work aims to heighten the security of SDN environments by building an IDS using the principles of machine learning and genetic algorithms. The proposed IDS is divided into two stages, the former to detect the attacks and the latter to categorize them. These stages reside in the switches and the controller of the network respectively. This approach reduces the dependency and the load on the controller, as well as providing a high attack detection rate.

Modelling and Mitigation of Open Challenges in Cognitive Radio Networks Using Game Theory

Cognitive radio networks (CRNs) are being envisioned as drivers of the next generation of ad hoc wireless networks due to their ability to provide communications resilience in continuously changing environments through the use of dynamic spectrum access. However, the deployment of such networks is hindered by the vulnerabilities that these networks are exposed to. Securing communications while exploiting the flexibilities offered by CRNs still remains a daunting challenge. In this survey, we put forward concerns relating to security, spectrum sensing and management, and resource allocation and performance of CRNs and model mitigation techniques using game theory. Game theory can be a useful tool with its ability to optimize in an environment of conflicting interests. Finally, we discuss the research challenges that must be addressed if CRNs are to become a commercially viable technology.

Securing CoAP Through Payload Encryption: Using Elliptic Curve Cryptography

The vision of the IoT is to not only make our everyday lives easier but also at the same time to ensure a secure environment. As the networking world moves closer towards an environment comprising of minimalistic ubiquitous nodes, IoT-based protocols cannot afford to accommodate security vulnerabilities. In this paper, we identify and mitigate the existing security flaws in the CoAP protocol of the IoT. A real-time system is developed to put the mitigated system into use and analyze the enhanced security. Additionally, we quantitatively look to evaluate the vulnerability of current implementation of CoAP and the magnitude of mitigation the method suggested in this paper provides. A secondary quantitative measure is used to prove that the overhead of the applied encryption is acceptable in terms of efficiency for the mitigation achieved.

A Survey of Fingerprint Recognition Systems and Their Applications

Recognition for authentication using biometrics is an intricate pattern recognizing technique. The process is really hard to architect and design, and choosing precise algorithms competent of fetching and extracting significant features and then matching them correctly, particularly in the cases where the quality of the fingerprint images are poor quality image capturing devices are used. Problems also occur where minutia are clearly visible on very small fingerprint area that are not exactly capture by camera. It is a false assumption that fingerprint recognition is a completely settled area regarding the authentication of a person just because it always give the correct identity of an individual. Fingerprint identification remains a very complex and intricate pattern-recognition system for authentication of a person.

Efficient Image Segmentation Using an Automatic Parameter Setting Model

Most image analysis methods perform segmentation as a first step towards producing the object description. In these methods both input and output are images only, but the output is an abstract representation of the input. Image segmentation is responsible for partitioning an image into multiple sub-regions based on a desired feature, such as edge, point, line, boundary, texture, and region. The most common segmentation methods use intensity-based images. Snakes or active contours (AC) are used extensively in computer vision and image processing applications, particularly to locate object boundaries. During a literature survey, it has been identified that many segmentation issues like gray values of pixels remain equal for a area, rapid change of image gradient, large gradient due to noise and identification of boundary between areas. The traditional adaptive distance preserving level set evolution method works fine for natural and synthetic images. However, it is necessary to set the performance parameters manually every time with respect to the type of input image. Hence, the proposed method of an automatic parameter setting model (APSM) improves the adaptive distance preserving level set evolution based on region by setting the performance parameters automatically with the help of an analysis of the image quality. The results show the effective performance of segmentation by reducing the number of iterations with an improved output quality.

Quantitative Evaluation of Panorama Softwares

Image stitching has been practiced in various computer vision and scientific study areas. Many different image stitching algorithms have been proposed by different research groups in the past, and there are many different image stitching software products available on the market. However, a comparison between different stitching software products and an evaluation of them has not been performed so far. Furthermore, most previous quality assessment approaches have not had an adequate number of performance matrices, while others have suffered from the adverse effects of computational complications. Our objective is to identify the best software for panoramic image stitching. In this paper we measure the robustness of different software products by assessing image quality of a set of stitched images. For the evaluation itself, a varied set of assessment criteria is used, and evaluation is performed over a large range of images captured in different scenarios using differing cameras. Results show that Autostitch performs relatively well for all types of scenes and for all types of dataset.

Emerging Trends in Big Data Analytics—A Study

Big data refers to exceptionally large datasets that are growing exponentially with time. The three key enablers for the growth of big data are (1) data storage, (2) computation capacity, and (3) data availability (Grobelnik M, Big-Data tutorial, 2012 [1]). This massive, heterogeneous, and unstructured digital content cannot be processed by traditional data management techniques and tools effectively, but this problem is overcome by using big data analytics. In this paper, we have discussed various big data services, languages, and data visualization tools. Big data helps organizations to increase sales and improves marketing results. It also improves customer service, reduces risk, and improves security. Both high storage and computation are important requirements for big data analytics. Information technology researchers and practitioners have faced the major challenge of designing systems for the efficient handling of data and its analysis for the decision-making process as the amount of data continues to grow. Big data is available in three forms, namely structured, unstructured, and semi-structured. The top ten big data technologies are (1) predictive analytics, (2) NoSQL databases, knowledge discovery and searching, (4) stream analytics, (5) data fabric for in memory computing, (6) distributed file stores, (7) virtualization of data, (8) integration of data, (9) preparation of data, and (10) quality of data. Amazon Elastic MapReduce, Apache Hive, Apache Pig, Apache Spark, MapReduce, Couchbase, Hadoop, and MongoDB are data integration tools used to manipulate big data accurately.

A Novel Telugu Script Recognition and Retrieval Approach Based on Hash Coded Hamming

Due to their many applications, optical character recognition (OCR) systems have been developed even for scripts like Telugu. Due to the huge number of symbols utilized, identifying the Telugu words is a very complicated task. Pre-computed symbol features are stored by these types of systems to be recognized or retrieved from a database. Hence, searching of Telugu script from the database is a challenging task due to the complication involved in finding the features of the Telugu word images or scripts. Here, we implement a novel Telugu script recognition and retrieval approach based on a method called hash coded hamming (HCH). Hash coding will be used as a feature extractor and the hamming distance will be utilized as a replacement for conventional Euclidean distance in order to measure the similarity between query and database images. Simulation analysis shows that the proposed scheme has a superior performance to the conventional approaches presented in the literature.

Clustering Method Based on Centrality Metrics for Social Network Analysis

The significance of a node in a social network is quantified through its centrality metrics, such as degree, closeness, and betweenness. However, many methods demonstrating the relevance of a node in the network have been proposed in the literature. In this digital smart world, the evolution of social networks occurs in various different directions at an unprecedented speed. A network evolution mechanism that provides the state of each node and its changes from its inception to its extinction over time will help in understanding its behavior. Often the strategy behind evolution is unknown and would not be reproduced in its totality. However, it is essential to understand behavior of the network as this can greatly facilitate its management before it becomes uncontrollable. A heuristics-based cluster method is proposed in this paper which combines centrality metrics and categorizes the entire network.

Impact of Node Mobility and Buffer Space on Replication-Based Routing Protocols in DTNs

A delay-tolerant network (DTN) is a kind of network in which nodes are not directly connected with each other so they communicate through intermediate nodes. As the mobility of nodes is so high in DTNs it is difficult to deliver a message without the creation of duplicate copies for distribution in the network. In this paper the impact of node mobility and the impact of buffer spaces on replication-based routing techniques called epidemic routing and sprays and waits routing has been assessed. To evaluate performance metrics, measures such as delivery ratio, drop rate, overhead ratio, and the number of replications have been used. To simulate the above routing protocols ONE (opportunistic network simulator) simulation was used.

Association Rule Mining Using an Unsupervised Neural Network with an Optimized Genetic Algorithm

The best known and most widely utilized pattern finding algorithm in data mining applications is association rule mining (ARM). Extraction of frequent patterns is an indispensable step in ARM. Most studies in the literature have been implemented on the concept of support and confidence framework utilization. Here, we investigated an efficient and robust ARM scheme based on a self-organizing map (SOM) and an optimized genetic algorithm (OGA). A SOM is an unsupervised neural network that efficaciously produces spatially coordinated internal feature representations and detected abstractions in the input space and is the most efficient clustering technique that reveals conventional similarities in the input space by performing a topology maintaining mapping. Hence, a SOM is utilized to generate accurate clustered frequency patterns and an OGA is used to generate positive and negative association rules with multiple consequences by studying all possible patterns. Experimental analysis on various datasets has shown the robustness of our proposed ARM in comparison to traditional rule mining approaches by proving that a greater number of positive and negative association rules is generated by the proposed methodology resulting in a better performance when compared to conventional rule mining schemes.

A Novel Approach for Digital Online Payment System

Nowadays digital transaction security is seen as essential in an online payment system. Earlier, cryptographic authentication techniques were used to make transactions very secure with third-party verification. However, in recent times, digital transactions have developed to allow online payments to be made directly from one party to another, without the intervention of the third party. This kind of P2P network transaction is achieved by utilizing the blockchain innovation. A blockchain uses the idea of Bitcoin. It isn’t observed by the central authority, but its clients direct and approve exchanges when one individual pays another for merchandise or administrations, dispensing with the requirement for outside confirmation. All finished exchanges are freely recorded as a block and each block is added one after other to form as a blockchain. In this paper, we present the workflow of a digital online payment system using the blockchain technique. We explain the secure sign-in procedure of the blockchain strategy. We elaborate on the effects of blockchain technology on the online transaction management system in terms of security and usability.

Ensemble-Based Hybrid Approach for Breast Cancer Data

Classification of datasets with characteristics such as high dimensionality and class imbalance is a major challenge in the field of data mining. Hence to restructure data, a synthetic minority over sampling technique (SMOTE) was chosen to balance the dataset. To solve the problem of high dimensionality feature extraction, principal component analysis (PCA) was adopted. Usually a single classifier is biased. To reduce the variance and bias of a single classifier an ensemble approach, i.e. the learning of multiple classifiers was tested. In this study, the experimental results of a hybrid approach, i.e. PCA with SMOTE and an ensemble approach of the best classifiers obtained from PCA with SMOTE was analyzed by choosing five diverse classifiers of breast cancer datasets.

Probabilistic-Based Rate Allocation Flow Control Technique for Traffic Governance in Wireless Sensor Networks

The proposed control mechanism delivers higher data traffic flow over a wireless sensor network. The proposed work is evaluated based on the probability of rate flow control method where the queue length is controlled by the traffic model based on the given traffic flow. The approach defines traffic governances based on the node mobility approach, where nodes are dynamically moved from short range to a more distant range. The link overhead and end-to-end delay are minimized in this technique, in comparison to the conventional controlling technique. Due to an early evaluation of congestion probability in the buffer unit, the blockage probability has been controlled.

Amended Probabilistic Roadmaps (A-PRM) for Planning the Trajectory of Robotic Surgery

Trajectory planning is an essential aspect of research into the use of pliable needles for surgical processes. Sampling-based algorithms can generate trajectories and reach the target avoiding obstacles. However, the trajectories cannot match the physical constraints of injecting the pliable needle into human flesh, as the trajectories are not continuous. Aimed at solving this problem, an enhanced probabilistic roadmap (PRM) is used in this work. A PRM generates trajectories for surgeries that are minimally invasive and simultaneously guarantees the effectiveness and continuity of the trajectory. In this research work, the classical PRM method is enhanced by using a shape preserving piecewise cubic hermite interpolation (PCHIP) technique, used to generate smooth trajectories, which are important for navigating the curved path of the pliable needle in surgery. Trajectories that have been generated using the PRM satisfy direction constraints approach in terms of both source and target positions. As a result, the trajectories produced by the pliable needle are dynamically and geometrically feasible. Results of simulations performed show the validity of the algorithm implying that it can be efficiently used in trajectory planning of pliable needles in real-time surgical operations.

Region-Based Semantic Image Clustering Using Positive and Negative Examples

Discovering various interest of users from massive image databases is a strenuous and rapid impel expedition region. Understanding the needs of users and representing them meaningfully is a challenging task. Region-based image retrieval (RBIR) is a method that incorporates the meaningful description of objects and an intuitive specification of spatial relationships. Our proposed model introduces a novel technique of semantic clustering in two stages. Initial semantic clusters are constructed in the first stage from the database log file by focusing on user interested query regions. These clusters are further refined by relevance feedback in the second stage based on probabilistic feature weight using positive and negative examples. Our results show that the proposed system enhances the performance of semantic clusters.

A Cost Effective Hybrid Circuit Breaker Topology for Moderate Voltage Applications

Compared to mechanical circuit breakers, with respect to speed and life, solid state circuit breakers based on modern high power semiconductors offers considerable advantages. During a short circuit the voltage profile of the power grid can be improved since the fault current is reduced. The distortion in voltage caused by a three-phase short circuit can be limited to fewer than 100 μs. In this paper, a theoretically approached active thyristor circuit based on a new hybrid topology of connecting the semiconductor devices in series and parallel is proposed. This permits an increase in supply voltage and fault clearance without arcing. In turn, and to get benefit from a current limitation, the circuit breaker is realized with the extinction of an electrical arc when the breaker is opened. Hence the proposed topology has led to a wider integration of solid state circuit breakers (SSCB) in existing power grids because of their cost effective nature when compared to turn-off semiconductor devices.

Configurable Mapper and Demapper for the Physical Layer of a SDR-Based Wireless Transceiver

In this paper, field programmable gate array (FPGA) implementation of an adaptive constellation mapper and demapper is discussed for use in a SDR-based wireless transceiver. The adaptive functions at the physical layer of wireless technologies play a key role in achieving optimum performance. These functions include forward error correction (FEC) coding, puncturing, orthogonal frequency division multiplexing (OFDM), constellation mapping, sub-channelization, and frame assembly etc. We present here constellation mapping and demapping that supports gray-coded BPSK, QPSK, 16QAM, and 64QAM modulation schemes. This block can be configured at run time so that you can use them in multi-user systems where each user may be operating with a different modulation scheme. The proposed mapper/demapper block is implemented on a Xilinx Virtex-II pro FPGA and it is characterized in terms of functional correctness, area, power, and speed. Experimental results show that our design takes 1360 gates and can run at a maximum frequency of 320 MHz.

Experimental Investigation to Analyze Cognitive Impairment in Diabetes Mellitus

Metabolic disorders and cognitive impairment are very common age-associated disorders. Alzheimer’s disease and diabetes are two common diseases and their possibility of occurrence increases as the age of a person increases. This paper proposes the percentage of type 2 diabetes patients that have a chance of developing Alzheimer’s disease. Pathophysiology and clinical patterns share common features in both the diseases as shown by epidemiological studies. There are a number of studies that show evidence of a connection between type 2 diabetes and Alzheimer’s disease but there is no proof of any biochemical mechanisms present yet. We focused our study and experiments on whether the alteration of factors like glycogen synthase kinase-3β activity, olfactory function, and ApoE genotypes can identify early cognitive impairment, which leads to Alzheimer’s disease.
