摘　　要：通过分析LEACH协议簇头选举算法的运行机制,针对无线传感器网络节点能量有限性的问题,在原有算法基础上提出在网络运行不同阶段的簇头选举中以能量和平均距离为参考因素的算法。最后,通过实验仿真证明改进后的算法相对均衡了节点能量的消耗并且有效延长了网络的生命周期。By analyzihg the operating mechanism of cluster-head election algorithm based on LEACH Protocol and to overcome the limitation of the network node energy of wireless sensor, an improved algorithm is proposed that in the different phases of cluster-head election algorithm, the energy and average distance should be considered as referential factor. The simulation results show that the improved algorithm saves the consumed energy of the network nodes and effectively lengthens the lifecycle of the network.
