Chapter 1. Wireless Sensor Network: Applications, Challenges, and Algorithms

Abstract
Wireless sensor network (WSN) is a collection of sensor nodes that distributed in an arbitrary manner to solve a particular problem. The position of the node is predefined and based on random nature. Each node directly or indirectly connected with the base station (BS). BS is used to control and manages all sensor nodes. WSN is used in several applications such as disaster management, entertainment, education, environment monitoring. Although the applications of WSN increase rapidly in the modern era, it has several limitations such as limited energy capacity of the nodes, shortage memory capacity of the nodes as well as limited computational capacity. These limitations cause frequently changing the infrastructure of the WSN which has high complexity, and it causes the failure of the current operation. Hence, to overcome these problems several nature-inspired algorithms are designed such as swarm optimization, ant colony optimization, particle swarm optimization, Africa buffalo optimization, genetic algorithm, teaching-learning based optimization, etc. The basic aim of these optimizations is to solve several conflicting objectives of the WSN efficiently in terms of some parameters.

Chapter 2. A GA-Based Fault-Aware Routing Algorithm for Wireless Sensor Networks

Abstract
Wireless sensor network (WSN) is the primary environment monitoring infrastructure of IoT system, where environmental information about hazard locations is collected through the collaborative functioning of sensor nodes. Considering the energy constraint of sensor nodes, energy efficiency is the primary requisite of protocols designed for WSN. Cluster-based routing protocols have been widely used to conserve sensors’ energy in WSN. Although, an extensive research has been done on cluster-based routing, but fault-aware routing is still an open research issue. In this chapter, we present a fault-aware routing algorithm called FAR for WSN-based on genetic algorithm (GA) approach. FAR is developed with a novel chromosome generation scheme which ensures that each CH in the network has a routing path to the remote station (RS). In FAR, we have derived a fitness function where the objective is to balance the load of CHs during data routing. The proposed algorithm has been extensively analyzed with some existing related algorithms and compared their performance in terms of different metrics like energy efficiency, number of alive nodes, and packet delivery ratio.

Chapter 3. GA-Based Fault Diagnosis Technique for Enhancing Network Lifetime of Wireless Sensor Network

Abstract
A wireless sensor network (WSN) is a collection of more than one sensor nodes which is used both collecting as well as sensing data from its environment (Rongbo in Int J Distrib Sens Netw 2010(1155):1–7, [1], Herbert and Donald in Schilling principles of communication systems. McGraw-Hill, New York, [2]). The main aim of this process is to achieve several operations efficiently in terms of different applications such as intelligent building, precise agriculture, medicine and health care, preventive maintenance, machine surveillance, disaster relief operation and biodiversity mapping. The stated applications are optimized efficiently in terms of cost, scalability and readiness. Although, there are so many fruitful advantages of WSN, but it consists of limited capacity of batteries which is insufficient during any operation. The sensor nodes are directly or indirectly connected with base station as well as sink node. Sometimes, due to network variation or failure of hardware sensor nodes fail to transmit the data packet. Moreover, due to limited energy, sometimes sensor node exhausts before the delivery of the data packet and gets converted into faulty node (Heinzelman, Chandrakasan and Balakrishnan in Energy efficient communication protocol for wireless micro sensor networks, pp. 8020–8030, [3], Bhajantri, Nalini in Int J Comput Netw Inf Secur 6(12):37–46, [4]). This faulty node treated as dead node during operation. So, there is need to design an effective algorithm for detecting as well as calculating total dead nodes and provide optimum solution. In this paper, an efficient technique is proposed based on the direct diffusion technique that aims to find optimum path by recovering dead nodes. The proposed algorithm enhances the network lifetime by reducing data packet loss as well as energy consumption.

Chapter 5. Fault Diagnosis in Wireless Sensor Networks Using a Neural Network Constructed by Deep Learning Technique

Abstract
Sensor nodes in wireless sensor networks (WSNs) are randomly deployed in hostile environments. Real-time experience shows that sensor nodes are prone to faulty. Different faults of sensor nodes are inevitable due to internal and external influences such as adverse environmental conditions, low battery, calibration and sensor ageing effect. Since WSNs applications rely on the fidelity of data reported by the sensor nodes, it is important to detect a faulty sensor and isolate them. Most of the existing fault detection techniques in literature are statistical based which demands sensor domain knowledge and the data from the neighbouring sensors. There may be a problem of detecting a sensor fault by analyzing the sensor data in distributed approach is non-trivial since a faulty sensor reading could mimic non-faulty sensor data. Currently, machine learning algorithms have been successfully used to identify and classify various types of faults in WSNs to avoid such kind of problems. However, the application of deep learning (DL) methods has sparked great interest in both the industry and academia in the last few years. In this chapter, neural network methods will be used in fault diagnosis in WSN with DL algorithms. The focus on diagnosis of fault includes hard, soft, intermittent and transient types.

Chapter 7. Intelligent Routing in Wireless Sensor Network Based on African Buffalo Optimization

Abstract
Applications of wireless sensor network (WSN) have experienced a rapid growth recently due to the heterogeneous nature of network topology. At different levels, different entities such as source node, sink node, hop nodes and base station (BS) in WSN are positioned at remote locations to perform specific assigned operations. Since each sensor node in WSN employs battery having limited capacity, it is imperative to determine optimal routing which otherwise may lead to network transmission failure. This present work aims to introduce a new approach based on the African buffalo optimization (ABO) routing in the WSN. ABO is a nature-inspired combinatorial optimization technique based on the behavior of African buffalos. Here, ABO acts as the main controller of the WSN and manages all the sensor nodes in correspondence with the BS. It also helps to transfer data packets from the source node to the sink node efficiently. Further, it enhances the network lifetime and improves other performance metrics of the WSN.

Chapter 8. On the Development of Energy-Efficient Distributed Source Localization Algorithm in Wireless Sensor Networks Using Modified Swarm Intelligence

Abstract
Source localization and tracking is an important application in wireless sensor networks. Sources are localized by measuring the direction of arrival from the signal impinging on the array of sensors. Most of the existing array signals processing algorithms to estimate the source directions of arrival are centralized-based which need more communication in the network. Therefore, a distributed maximum-likelihood-based direction of arrival estimation strategy is developed by following the diffusion cooperation among the nodes in sensor network to minimize the communication overhead. Modified particle swarm optimization is proposed to optimize the multimodal maximum-likelihood function in distributed scenario. The experimental results exhibit improved performance for the distributed method over non-cooperative algorithm. Further, clustering-based approach is proposed where the nodes are clustered and then act as random arrays. Then, each cluster estimates the source direction of arrival by optimizing the maximum-likelihood function locally with cooperation of other clusters. The distributed in-clustering approach offers low communication overheads and better estimation accuracy compared to other methods.

Chapter 10. A Comprehensive Survey of Intelligent-Based Hierarchical Routing Protocols for Wireless Sensor Networks

Abstract
Routing protocols are responsible for discovering and maintaining energy-efficient routes in wireless sensor networks (WSNs) to make reliable and efficient communication. The main aim of the routing protocol design is collecting data of the sensor field efficiently. In general, routing in WSNs can be classified into three groups: flat routing, hierarchical routing, and location routing. According to the literature, hierarchical routing has more advantages compared to other types, for example, hierarchical routing reduces the redundant data transmission and balances the load among the sensor nodes in an efficient way. Recently, many intelligent-based hierarchical routing protocols are developed for controlling the consumption power of WSNs. Selecting an appropriate routing protocol for specific applications is an important and difficult task for the designer of WSNs. Therefore, this chapter presents a comprehensive survey of the recently intelligent-based hierarchical routing protocols that are developed based on Particle Swarm Optimization, Ant Colony Optimization, Fuzzy Logic, Genetic Algorithm, and Artificial Immune Algorithm. These protocols will review in detail according to different metrics such as WSN type, node deployment, control manner, network architecture, clustering attributes, protocol operation, path establishment, communication paradigm, energy model, protocol objectives, and applications. Moreover, a comparison between the reviewed protocols is investigated here depending on delay, network size, energy efficiency, and scalability with mentioning the advantages and drawbacks of each protocol.

Chapter 11. Qualitative Survey on Sensor Node Deployment, Load Balancing and Energy Utilization in Sensor Network

Abstract
Sensor Network is typically event-based systems. A wireless sensor network consists of many sink nodes to which it subscribes to and streams by expressing interest or queries submitted by various applications by users or organizations in general. As the sensors are battery-operated devices energy plays prime criteria in the sustainability of the network. If the size of the sensor tree pertaining to a network increases then the number of slots required for the scheduling transmission also increases. Sensors are deployed to cover various target points according to the application need; hence the proper deployment of the coverage or data gathering nodes is essential to increase the lifetime of the network. Proper deployment of coverage nodes plays a key role in load balancing and formation of the optimal subtree along with its respective base station and relay sensors. Various stochastic, deterministic, as well as heuristic-based algorithms incorporating optimization techniques to perform the node distribution has been developed and researched over the years. Researchers have also developed variegated models with bio-inspired algorithms like genetic algorithm, PSO algorithm, etc. to tackle some of the crucial problems of WSN. The paper provides a survey of some of the models and algorithms used for sensor node distribution, data aggregation, and discuss the various issues related to load balancing—advantages and disadvantages according to various applications.

Chapter 13. TLBO Based Cluster-Head Selection for Multi-objective Optimization in Wireless Sensor Networks

Abstract
Day by day the applications of Wireless Sensor Networks (WSNs) increases rapidly due to its flexibility and efficient functionalities in our life. In this network, multiple sensor nodes are connected together to achieve the purpose of the users. Here, the purpose of the user is anything related to sensing information from the environment. In WSN, Cluster-head (CH) is a node that plays the role of main controller within the network. It helps to manage and control all other sensor nodes of the network. The CH node is superior to other nodes with respect to energy capacity. Each node of the WSN is consists of the limited capacity of battery which is insufficient for any operation. During operation, battery cannot be charge or replace. So, energy is a crucial parameter of the network. Hence, CH selection becomes difficult task in WSN. In this paper, an intelligent method is proposed for CH selection in WSN using Teaching-Learning-Based-Optimization (TLBO). This optimization consists of two basic elements such as teacher and student based natural relation between both entities. The TLBO helps to optimize several conflicting objectives of the network efficiently in terms of learning methods. Finally, it helps to select CH efficiently and dynamically in each iteration of the network.
