Survey on Algorithms for Energy Efficient Cluster Head Selection in Wireless Sensor Networks

Wireless Sensor Network (WSN) is a large collection of tiny self-aware, battery-operated, analyzable sensor network which integrates sensing, computation and communication in a single tiny device. These tiny devices can be used for ample number of remote sensing applications. Increasing network life time is one of the major design problems in Wireless Sensor Network as they have limited energy source. Clustering the nodes is one of the effective approaches to minimize energy consumption. Clustering is group of nodes in independent clusters and each cluster comprises of one or more cluster head based on network size. The nodes transmit sensed data to the respective cluster heads which in turn transmit the aggregated data to base station. Clustering algorithms enhance the lifetime of networks by avoiding long distance communication of nodes to base station. In this literature survey, various clustering approaches are discussed with working of few Clustering algorithms and distinguish them based on performance of algorithm
