The sensors in sensor networks have limited energy and thus energy preserving techniques are important. The low-energy adaptive clustering hierarchy (LEACH) technique improves energy efficiency of the sensor network by selecting a cluster head, and having it aggregate data from other nodes in its cluster and transmit it to the base station. In this paper, we propose three techniques, which we will call collectively Energy Efficient LEACH (EEL), that improve on LEACH to significantly reduce energy consumption and increase the lifetime of the sensor network. Simulation results using the NS-2 network simulator show that EEL improves LEACH by 37% with respect to network lifetime.
