JWCN_V5_N4_RP2 P. Santhanakumar G. Arun Sampaul Thomas Journal On Wireless Communication Networks 2320 - 2351 5 4 10 14 Clustering, Cluster Head, Energy Consumption, Network Lifetime Clustering is a popular routing technique in configuring Wireless Sensor Networks (WSNs). It can determine the communications between all nodes to collect data in an efficient manner. It handles the main challenge of energyefficiency in WSNs, and can be used to re-configure the network according to changes in the nodes' conditions. In this paper, an energy aware clustering algorithm is proposed for utilizing the energy efficiency and prolonging the lifetime of the network. The proposed algorithm elects the Cluster Head based on the parameter of residual energy. The Cluster Head node gathers the information from its members and forwards it to the Base Station. The proposed algorithm constructs the virtual circle for balancing the energy consumption among the sensor nodes. The simulation results show that the proposed algorithm utilizes the energy efficiently and extends the lifetime of the network efficiently.
