摘　　要：为减少无线传感器网络能耗、延长网络的生存周期,基于经典的低功耗自适应分簇算法(LEACH),提出了一种新的能量有效的分簇算法.算法的主要思想是综合网络能量分布和簇首间位置分布来优化簇首选择,从而在使簇分布更均匀的同时,进一步保证了网络内节点负载均衡.仿真和分析表明,该算法是一种有效的分簇路由算法.In order to reduce the energy consuming and prolong the life span of wireless sensor network, an energy efficient clustering algorithm was proposed based on low energy adaptive clustering algorithm （LEACH）. The distribution of network energy and the distance between cluster heads were taken as the parameter to optimize the process of cluster head selection. It can balance the distribution of clusters and provide the energy load＇s proportionality of sensor node. Both simulation and analysis show that it is an effective cluster-based routing protocols.
