Target Tracking in Wireless Sensor Networks Using NS2

Wireless sensor network has enormous number of sensors spread over a geographic zone. Each mote in WSN has the ability to communicate with other motes and can process the data in limited capacity. Localization is a technique in which we estimate the location of sensor nodes. In wireless sensor network, nodes locations are not fixed. So to track the target, many solutions come to the mind like GPS, RFID, Bluetooth, Multilateration and Trilateration. In this paper, we use a simple algorithm which reduces the energy usage by minimizing the communication overhead and track the target efficiently.

Taking Away the Green Screen—A Brief Discussion of a Multidisciplinary Approach to IoT via, Smart Parking and Interaction Design

“See a need, Fill a need” Wedge et al. (Robots 20th Century Fox, [1]) though these words can aptly sum up an entrepreneurial spirit, they are also a potentially good attitude for finding relevant solutions to global environmental issues. The important question that arises is how the need is filled? Long term, sustainable and creative solutions are required to reduce the impact of the human footprint. A multidisciplinary approach has great potential, as it is capable of combining a variety of domains and enriching the knowledge base. This paper will discuss a smart parking project to address the issues of carbon emissions, time management and congestion in cities whilst the 2nd project portrays a new approach to interacting and designing computers inspired by efficient biological systems.

Automatic Lung Field Segmentation Based on Non Negative Matrix Factorization and Fuzzy Clustering

Obtaining accurate and automated lung field segmentation is a challenging step in the development of Computer-Aided Diagnosis (CAD) system. In this paper fully automatic lung field segmentation is proposed. Initially, a visual appearance model is constructed by considering spatial interaction of the neighbouring pixels. Then constrained non-negative matrix factorization (CNMF) factorized the data matrix obtained from the visual appearance model into basis and coefficient matrices. Initial lung segmentation is achieved by applying fuzzy c-means clustering on the obtained coefficient matrix. Trachea and bronchi appearing in the initial lung segmentation are removed by 2-D region growing operation. Finally, the lung contour is smooth by using boundary smoothing step. The experimental results on different database shows that the proposed method produces significant DSC 0.987 as compared to the existing lung segmentation algorithms.

Competitive Advantage Through Social Media: A Study of Indian Firms

The purpose of this paper is to visit the role of social media in attaining or/and sustaining competitive advantage. Not before some 5–10 years, especially in the Indian context, was social media this active and influential. Internet existed merely as a source of information; and nothing more. Technological and social advances have led internet to give birth to an entirely new phenomenon called “social media”. Twitter, Facebook, LinkedIn, and many other web platforms have been established. People share their views, companies promote themselves, all the protests and campaigning is done, very much through social media. In this changed time, companies are opting to stand out among their competitors through the use of social media. In proposing out the new social marketing strategies, this paper contributes to the literature pool as well as opens scope for practicing new ways to gain advantage through social media.

Novel Strategy for Fairness-Aware Congestion Control and Power Consumption Speed with Mobile Node in Wireless Sensor Networks

The power issue in wireless sensor network (WSN) stays one of the real barriers keeping the complete abuse of this technology. The WSN is a dense network of sensors which sense the environmental conditions, process and propagate that data towards sink node. Limited battery life of sensor node and unbalanced utilization of that energy can affect the lifetime of the entire sensor network. In proposed work, mobile nodes are used to transmit the data nearby the area where the power consumption of the nodes is more. The mobile node reduces the workload and congestion of the nodes which is controlled by adjusting the reporting rate (RR) according to the buffer occupancy level. In this paper, we have correlated the existing Ad hoc on demand vector (AODV) routing protocol with our new approach to the delivery of power consumption. The proposed work evaluate the performance of the lifetime and energy consumption of the WSN with and without mobile nodes and results achieved by adjusting the number of mobile nodes, location and the speed of mobile node. The RR is also adjusted to control the buffer occupancy of each node and mitigate the congestion that occurs in the sensor network. Based on this simulation results, this proposed work increases the lifetime of the nodes whose power consumption speed is high and enhances the life of the entire network. The use of a dual threshold for buffer and mobile node can reduce the congestion and the waiting time for data reducing the delay.

Two Stage Wireless Sensor Node Localization Using Firefly Algorithm

Locations of the sensors in wireless sensor networks usually have to be known. Wireless sensor networks contain large number of sensors so installing global position system device in each of them is not acceptable. Few anchor nodes with known positions are usually used. Estimating sensor nodes positions from radio strength signal index is a hard optimization problem. In this paper we proposed a two stage algorithm with semi-mobile anchors that uses swarm intelligence firefly algorithm for optimization. The proposed algorithm was tested by simulation of standard benchmark wireless networks where it obtained better results compared to other approaches from literature.

Detection of Brain Tumor from MR Image Sequence Using Image Segmentation and Blob’s Centroid

This paper proposes a method to search for a probable tumor in magnetic resonance (MR) images of a human brain. Typically, a tumor can be found in some contiguous images of the MR sequence and positions of its appearance in such contiguous images usually have similar centroid thus their corresponding projections should be able to be detected automatically in order to support a user or a doctor for further diagnosis. Once region of a probable tumor is detected, matched checking between a pair of contiguous MR images can be done and relabeled to indicate the same area of the tumor amongst sequential images. Any regions without match between contiguous images are initially considered as irrelevant components and will not be analyzed further unless the doctor indicates otherwise. Then, ratio of tumor to brain is calculated to support as an initial diagnosis of tumors appeared in an MR image sequence .

A Project Metric Model for Assessing ICT Project Success/Failure

Project success metrics play a vital role in project control as they focus on project deliverables as justification of success. However, this traditional view is not sufficient for measuring the degree of success/failure with consideration of the resulting Return on Investment (ROI). This study presents a model project management metric for assessing project success or failure which sufficiently accounts for necessary expectations from the user community. The model was evolved from existing project management metrics by adding features to justify precise measurement of degrees of project success/failures.

An Intelligent Hardware Calibration Scheme for Real Time VoIP Applications

VoIP (voice over IP) is a methodology for the transmission of data, voice, video, messaging and chat services over Internet Protocol. The quality of VoIP is heavily dependent on the type of hardware used. Hardware calibration is a mechanism for selecting a suitable hardware for the required system characteristics. Sometimes, it becomes quite difficult to select the possible hardware with optimal cost from a class of processors which provide the same services. The aim of this paper is to use an Intelligent hardware calibration scheme for VoIP based real-time applications by considering different parameters like CPU utilization, cost, RAM utilization, jitter and delay. The selection of the processor by using an Intelligent scheme saves the execution time and availability of resources when it takes calls per second as input and gives output as whichever hardware is recommended for call manager to handle a different number of calls at an optimized cost. In this paper, Fuzzy Analytic Hierarchy Process (FAHP) based scheme is proposed which allows the user to make the best decision from a set of available choices to compare a set of processors that would help service providers to optimally provide different types of VoIP based services.

Automatic Sub Classification of Benign Breast Tumor

This paper describes about automatic classification of benign lesions. Our re-search work mostly aims at development of a data driven effective classification system to determine type of benign breast tumors. The existing system in medical field identifies the type of benign breast tumor based on histopathological report obtained after a painful surgical process. Our target is to develop a system that would work without histopathological attributes to avoid pains to the patient. Our focus was to eliminate the role of histopathological attributes in the detection of benign tumor type. So we tried to identify correlation of histopathological features with mammographic image features and patient history features in order to explore if histopathological features can be replaced by corresponding correlated features. With replaced attributes we gain training accuracy for J48 as 79.78% and with SVM 81.91%. We obtained testing accuracy for J48 and SVM as 100% and 90.90% respectively.

Prevention of Conjunct Black Hole MANET on DSR Protocol by Cryptographic Method

As in MANETs the infrastructure is not present they are more vulnerable for attack which encourages the attacker nodes to become part of the network. A lot of efficient protocols have been proposed in this field. All of these routing protocols depend only in the conviction and supportive environment. Conjunct Black hole attack is a network layer attack in which the malicious node makes use of routing protocol to pretend that it has the shortest path for the destination. In our research work we proposed a protocol, using RSA algorithm to eliminate Conjunct Black hole attack, even comparison with the DSR protocol is shows by the effects of the performance metrics in terms of delay and throughput of the network in the AD Hoc network environment.

Electrical Energy Output Prediction Using Cuckoo Search Based Artificial Neural Network

The environmental ever demanding improvement along with the increasing demand of electricity attracted researchers in designing efficient, accurate and robust models. Such models are used mainly to predict the energy output of combined steam and gas turbine mechanisms. The applicability of these systems depends on their sustainability. It is inevitable to predict the combined mechanisms output energy in order to produce more trustworthy mechanisms. Since the acceptability of the aforesaid turbine systems is judged in terms of their profitability, the output energy prediction plays a vital role. In machine learning, the neural network (NN) based models has been proven to be a trustworthy in critical prediction tasks. However, the traditional learning algorithms in the NNs suffer from premature convergence to local optima while finding the optimum weight vectors. Consequently, the present work proposed a Cuckoo Search (CS) supported NN (NN-CS) and a Particle Swarm Optimization (PSO) supported NN (NN-PSO) to efficiently predict the electrical energy output of the combined cycle gas turbines. In the current study, five features are extracted, namely the ambient temperature, relative humidity and ambient pressure in gas turbines and exhaust vacuum from a steam turbine. The results established the improved performance of the CS based NN compared to the multilayer perceptron feed-forward neural network (MLP-FFN) and the NN-PSO (particle swarm optimization) in terms of root mean squared error. Proposed NN-CS achieved an average of 2.58% the mean square error (RMSE).

Estimation of Heterogeneity to Improve Robust Anisotropic Diffusion

Anisotropic diffusion (AD) become a prominent image enhancement and de-noising method after its introduction in 1987. However, anisotropic diffusion requires selection of a diffusion function whose definition remained ad hoc. Additionally, AD requires determining a scale parameter on which the final result is intimately related. Typically this parameter is chosen in ad hoc basis which makes difficult to compare the final output. In literature, Median absolute deviation (MAD) is proposed as a heterogeneity scale for using with robust anisotropic diffusion (RAD). Despite its strong statistical foundation, diffusing an image by RAD results in undesirable staircasing effect and artefacts are created in presence of noise. In this paper, we propose a robust L-estimator scale that correctly demarcates the homogenous and heterogeneous regions of an image and smoothens the image with minimal staircasing effect. Experimental results show that this scale remains effective in presence of heavy noise.

Efficient Economic Profit Maximization: Genetic Algorithm Based Approach

Economic profit is the main governing power of any industrial and socio-economic growth. It is imperative to maximize profit related with economic systems to retain economic stability. Traditional methods involving Lewis model has been found to be unsuitable in terms of computational complexity. Motivated by the recent developments and successful application of meta-heuristic algorithms in achieving potent solutions, the present work proposed efficient meta-heuristic algorithm to support the profit maximization formalism. The genetic algorithm (GA) is employed to maximize the profit in terms of the total revenue (TR) and total cost (TC). The real parameter objective function depicting profit has been gradually optimized by GA. Experimental results suggest that the GA based profit maximization method is extremely fast, accurate and robust.

Query Optimization is an important process in Relational databases. Here, we present an overview of the Query Optimization process, with a focus on providing insight of MySQL sub-queries to optimize Join Operation. Efficient join processing for sub queries is one of the most fundamental and well-studied tasks in database research. For a given query, there are many plans that can be considered, though the output will be the same, but amount of time required is a key consideration. In this work, we examined existing algorithms for the way the sub queries are joined over many relations and described a novel sorting based algorithm to process these queries optimally. The algorithm is implemented and the results are compared with current strategies of MySQL. The proposed sorting based algorithm outperforms current algorithms without applying DBMS’ advanced techniques like parallel processing, hashing etc.
