无线传感器网络LEACH路由协议的改进

摘要

从簇的形成以及簇首的选取2个方面对LEACH协议进行了改进,使簇首尽可能的按照节点的稠密程度进行分布,并能将剩余能量较高的节点优选为簇首.仿真实验表明:改进后的LEACH协议能够延长节点存活时间,减小网络能耗.%This paper aims to improve the form of the clusters and the choice of the headcluster. Not only the headculster is assigned in accordance with its density as far as possible, but also the node that has remained more powerful will be the headcluster when it chooses the headcluster. The simulation experiment results using NS-2 show that the improved LEACH protocol can extend the time the nodes are active and reduce network energy consumption.
