In wireless sensor network (WSN), each node has limited energy resources and the lifetime of network is one of the most critical issues in WSNS. Because LEACH protocol has some defects including indefinite and unevenly distributed cluster heads. By studying the energy consumption of nodes and cluster heads on data acquisition and transmission, we propose Balancing Energy Consumption LEACH (BEC-LEACH) protocol to prolong the lifetime of the network. The protocol proposed aims to study the clustering algorithm and take geographical location and remaining energy of nodes as the main factor for cluster heads selection. The simulation results show that BEC-LEACH algorithm can more effectively balance the energy consumption of nodes and prolong the lifetime of network compared with LEACH.
