In this paper, clustering in terms of energy efficiency in WSN is explored and proposed Energy Balanced Clustering in Wireless Sensor Network (EBC). Algorithms for energy balanced cluster formation, cluster head selection, intra cluster and inter cluster communication in WSN are proposed. Furthermore, using OMNet-4.0 simulation performance of proposed protocol is compared with LEACH and EEMC using parameters like energy per packet and throughput. Simulation results demonstrate that EBC is effective in prolonging the network lifetime as well as in improving throughput, than LEACH and EEMC. © 2010 IEEE.
