　　LEACH是一种经典的WSN分层路由协议，它采取自适应分群算法，一定程度上延长了网络生存期。该文介绍了LEACH协议的工作流程，其中关键的步骤是：分群建立阶段和数据稳定传输阶段；最后通过LEACH的优缺点分析，总结分析了当前不少国内外研究学者基于LEACH思想提出的各种改进策略。仿真实验结果表明，这些改进策略，相比于传统的LEACH在延长网络生存时间、节省能量和平衡节点能量消耗等方面有更优的性能。

LEACH(Low Energy Adaptive Clustering Hierarchy)is a classical routing protocol for WSN which takes the adaptive clustering algorithm.All nodes will bear the energy consumption averagely,which can extend network lifetime in a manner.This paper introduces the traditional LEACH Protocol,the key steps are:the cluster head selection and cluster formation,data transmission;Finally,this paper analysis the advantages and disadvantages of LEACH,summarizes improved strategy based on LEACH protocol,what scholars at home and abroad put forward.Simulation results show that,compared to the traditional LEACH,these improvement strategies has better performance in prolonging network life time,saving energy and balancing the node energy consumption etc.
