摘　　要：针对无线传感网络中高效路由协议的设计问题,基于传感器节点的剩余能量提出一种分时分簇的改进LEACH算法。算法通过分时分簇方式,有效克服了传统LEACH算法中簇首数目不稳定的缺陷,且不会额外增加网络的能耗,使得簇首在整个网络中的分布以及网络的能量消耗更加均衡,有效延长了传感器网络的正常工作时间。仿真实验验证了改进算法的有效性。For the problemof effective routing protocol in wireless sensor network,this paper puts forwardan time-division and clusteringalgorithm of LEACH based on the Residual Energy(LEACH-RE) of sensor nodes. By time-cluster and clustering method,LEACH-RE solves the problem of unstable cluster-head number that exists in LEACH algorithm without increasing the energy consumption of the network.In addition,the distribution of clusters and energy consumption in the network are well balanced.The normal lifetime of the sensor network is effectively extended. Simulations improve the effectiveness of the algorithm.
