摘　　要：低能自适应聚类路由协议(LEACH协议)是为无线传感器网络设计的一种低功耗自适应分层路由协议,具有延长网络生命时间的作用。为了均衡无线传感器网络节点的能耗,延长整个网络的生命周期,通过对LEACH协议的研究,对簇首的选取和簇首与Sink的通信机制进行优化,提出了一种改进的LEACH协议的分簇路由算法。通过Matlab仿真实验证明,改进后的LEACH算法在网络生命周期和网络能量消耗等方面比LEACH算法有较大的提高。The LEACH protocol is a low-energy adaptive clustering hierarchy protocol designed for the wireless sensor networks,which can prolong the network lifetime.Based on the research of the LEACH protocol,improves the cluster head selection and the communication mechanism between cluster head and sink to balance energy consumption of wireless sensor networks and prolong the network lifetime.Results of the simulation experiment using Matlab show that the network life-cycle and network energy consumption of the modified LEACH algorithm have been greatly improved than the LEACH algorithm.
