Load Balancing and Optimization of Network Lifetime by Use of Double Cluster Head Clustering Algorithm and Its Comparison with Various Extended LEACH Versions

Authors : Akanksha Mohan Gupte, Suryalok Sarkar and A. Karthikeyan

Abstract: The energy efficiency and optimization of network lifetime are the most important design criterion in Wireless Sensor Networks (WSNs). This is because WSNs are equipped with limited non-restorable supply of energy. In this study, a Double Cluster Head Clustering Algorithm is presented whose basis is Particle Swarm Optimization (PSO). In this algorithm, two cluster heads namely the Primary Cluster Head (PCH) and the Secondary Cluster (SCH) are generated. PCH is used to receive and aggregate data from its cluster member nodes and send the aggregated data to SCH. SCH then transmits this aggregated data to base station directly. For larger networks this algorithm certainly improves the basic PSO as there is a division of work load among the cluster heads which results in balanced energy utilization throughout the network. This protocol is then compared with various extended versions of LEACH protocol and the effect of all these protocols is studied collectively to optimize the network lifetime.
