【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。更多还原

【Abstract】 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.更多还原
