摘　　要：在无线传感器网络中的LEACH协议是一种自适应聚类路由算法.由于LEACH协议存在着无法控制簇首在网络中的分布位置、簇首选择方式限制条件不够等缺点导致能量消耗太大.基于簇头能量限制和双簇头路由方式,对LEACH协议进行了改进,设计了一种降低能耗的双簇头非均匀分簇路由协议.双簇头非均匀分簇路由协议采用NS2进行网络仿真实验,通过仿真结果的分析以及与LEACH协议的对比,证明双簇头非均匀分簇路由协议有效提高了网络能耗的均衡性.The LEACH protocol for wireless sensor networks is a adaptive clustering routing algorithm. Because LEACH protocol has no control on distribution of the of cluster head in the network, cluster head selection method is restrictions, led to too much energy consumptiorL Based Cluster head energy restrictions and dual--cluster head routing, improvements and design a dual cluster heads non--uniform clustering routing protocol reduce energy consumption. Improved routing protocol using NS2 network simulation experiments carried out and compared and the LEACH protocol, through the analysis of simulation results to verify that the improved protocol improved network energy balance.
