摘　　要：基于LEACH路由算法,分析了无线传感器网络分簇路由机制,重点分析了LEACH及其两个改进算法LEACH-EI和LEACH-EA。用Matlab平台对LEACH算法和改进后的算法进行仿真分析,结果表明:改进后的算法在延长网络生命周期和减少能量消耗上比LEACH算法有了很大改善,LEACH-EI算法适用于比较小型的、且运行时间较短的网络,而LEACH-EA算法则适用于比较大型的网络。The cluster-based routing protocol based on LEACH route algorithm for wireless sensor networks was analyzed. LEACH algorithm and its two improved algorithms, LEACH-EI and LEACH-EA, were stressed. The algorithms were simulated by using Matlab platform. The result indicates that LEACH-EI and LEACH-EA were greatly improved upon LEACH algorithm in regard to extending network life-time and reducing energy consumption. Compared with LEACH-EA, LEACH-EI is more suitable on mini-type networks, i. e. , LEACH--EA is more suitable in large-scale wireless sensor networks.
