摘　　要：在无线传感器网络中,与平面路由协议相比,分簇路由协议具有一定的优势。它具有拓扑管理方便、能量利用高效、数据融合简单等优点,成为当前路由协议研究的重点。本文以低能量自适应聚类(LEACH)为例,对分簇路由协议进行了分析。在此基础上,提出改进了的LEACH ED_LEACH(Base on Energy and Distance factors-Low-Energy Adaptive Clustering Hierarchy),通过使用MATLAB进行了仿真,仿真结果表明ED_LEACH算法能更有效地延长网络寿命。Compared with the plane routing protocol, the cluster-based routing protocols have certain advantages. They are convenient in topology management, energy-efficient and easy for data aggregation, and therefore have become the focus of researches in routing protocols at present. Low-Energy Adaptive Clustering Hierarchy （LEACH） is taken as an example for analyzing the cluster-based routing protocols. On this basis, ED-LEACH （Based on Energy and Distance factors-Low-Energy Adaptive Clustering Hierarchy） is proposed. The simulation results show that ED LEACH is effective in prolonging the network lifetime by MATLAB.
