一种基于LEACH的高效路由协议

Efficient routing protocol based on LEACH

为解决无线传感器网络路由协议研究中降低单个节点能耗,延长网络生存期等问题,在分析传统的LEACH算法基础上,针对簇头选举、簇形成过程两个问题加以改进,设计了一种基于LEACH的高效路由协议。依据节点的剩余能量、离基站的距离等因素产生簇头;依据普通节点到簇头的距离、簇头到基站的距离等因素成簇。研究结果表明,改进算法在降低节点能耗、延长网络生存期等性能方面有明显的提升。

In order to solve the problems of reducing the network energy consumption and improving the lifetime in the study of the routing of wireless sensor networks,in the analysis of the traditional algorithm based on LEACH,aiming at cluster-head election and cluster forming,an efficient routing protocol was proposed.In cluster-head election,the nodes consider the remaining energy of the nodes and the distance from the base station as the main factors;while forming cluster ordinary nodes consider cluster formation according to communication cost by the distance from cluster-head and the distance from base-station to the cluster-head.The Simulation results indicate that the new algorithm has significantly performance in reducing the energy consumption of nodes and prolonging the lifetime of the network.
