The hierarchical routing protocol in the wireless sensor network (WSN) is widely applied because of its good network stability and effective communication capability. As the earliest hierarchical routing protocol, Low-Energy Adaptive Clustering Hierarchy(LEACH) had low energy efficiency without considering the state of nodes. In this paper, we propose an energy efficient LEACH-based protocol to improve LEACH. The state of the cluster heads in the previous rounds, as well as residual energy and alive nodes density, are used as indicators to measure the current round cluster head selection. The modified protocol fixes the issue that the number of cluster heads dropped rapidly with dead nodes increase. The simulation results show that the proposed protocol can prolong the network lifetime of WSN effectively, and reduce the energy consumption with the balancing energy distribution.
