摘要
文章针对无线传感器网络中的LEACH协议进行研究和分析,指出其簇头数目不均衡与节点负载不均衡的问题。通过分析LEACH协议和网络特性,给出基于节点能量消耗模型网络中要选举的最佳簇头个数和节点负载均衡改进算法,并利用NS对改进算法进行仿真。
This paper investigates the LEACH protocol and points out its disadvantages.Through analyzing characteristic of network and LEACH protocol,we propose two improved schemes of the LEACH protocol to prolong the lifetime of the network and enhance the efficiency of energy utilization.Finally,we show the efficiency of the proposed schemes by simulations.
