Analysis of Load Balancing Technique using Clustering Approach by PSO Algorithm

Wireless sensor Networks made up of nodes, where each node is connected to one or more number of sensors. WSN consists of a large number of low-cost, low-power, multifunctional sensor nodes. The life of sensors depends on their energy. When sensors in the network communicate with each other their energy get lowered and after some time they may die and because of that the network fails. Therefore our aim is to reduce the energy consumption and increase the sensor network lifetime. As the energy available in the sensor nodes used in WSN is limited, therefore we are trying to propose the technique to maximize lifetime of WSN by PSO algorithm. In this paper the selection of cluster head is done via PSO algorithm. Particle Swarm Optimization (PSO) is the technique used for placing the sink node. The sink node is at optimal position. The cluster head is selected on the basis of energy of the clusters and connectivity among the clusters. The cluster head then communicate with the Base Station (BS)

AN APPROACH FOR FAULT DETECTION AND FAULT MANAGEMENT IN THE WIRELESS SENSOR NETWORK TO EXTEND NETWORK LIFETIME

A mobile wireless ad hoc sensor network (MANET) consists of a group of homogeneous or heterogeneous mobile communicating hosts that form an arbitrary network interconnected via by means of several wireless communication media without any fixed infrastructure. In such network the delivery of the data packet from source to destination may fail for various reasons and major due to failure-prone environment of networks. This may happens due to the topology changes, node failure due to battery exhaust, failure of the communication module in the wireless node and results in the link failure. This paper addressed the major problem of link failure in the WSN and with the aim of providing robust solution so as to satisfy the stern end-to-end requirements of QoS-based communication networks. In this paper we modifies existing fully distributed cluster-based routing algorithm by addressing local recovery for the link failure. Performance of this new fault-tolerant fully distributed cluster-based routing algorithm is evaluated by simulating it in NS2 environment and we show that it performs better than the existing algorithm and provide better solution for fault detection and fault management along the QoS paths
