摘　　要：无线传感器网络由于节点能量的限制,在组网中必须要充分考虑到节点能量的情况,以避免由于节点的能量耗尽,造成网络分割。针对经典无线传感器网络协议LEACH没有考虑节点能量的情况,提出了一种基于LEACH的改进协议。该协议实现了对簇头选择的优化,以及对簇头和基站通信路径的优化。OPNET仿真实验结果表明,该协议能有效地延长网络的生命周期,推迟网络分割的出现。In wireless sensor network, the node energy is limited.In order to avoid the network segmentation caused by node energyexhaustion, ,the node energy must be considered fully in networking As no consideration on node energy is done in the classic LEACHprotocol of wireless sensor networks, this paper presents an improved protocol based on LEACH.This protocol optimizes the cluster headselection and cluster head and base station communication path. The OPNET simulation results show that the improved protocol canprolong network life cycle and delay the time of Network detachment.
