This paper proposes a clustering scheme to improve energy efficiency for cluster-based wireless sensor networks (WSNs). In order to reduce the energy dissipation of transmitting sensing data at each sensor, the proposed fixed algorithm uniformly divides the sensing area into clusters where the cluster head is deployed in the center of the cluster area. Moreover, to improve the energy efficiency in the cluster based on the fixed clustering, the cluster head is elected by the LEACH scheme. Simulation results show that the proposed low-energy fixed clustering (LEFC) definitely reduces the energy consumption of the sensors and outperform LEACH with more 60% network lifetime.
