摘要

针对传统LEACH协议的不足

提出了一种改进方案.通过改变原有LEACH协议中簇头以轮为单位更换的方案

采用多个条件判定其簇头节点是否变更

从而节省簇头更换所带来的能量消耗

增加了数据传输总量

可以增加sink节点接受到的数据总量.仿真结果表明

与传统的LEACH协议相比

改进后的算法LEACH_CHE具有更高的能量使用率

更长的生存时间而且接受的数据量更多.

Abstract

An improved scheme is proposed under the consideration of the defect of LEACH in this paper.This proposal determines whether the cluster head has been changed by means multiple conditions instead of the original LEANCH protocol which takes the unit of round as the cluster head.In that way

the energy could use for data transmission that is can increase the total amount data which sink node receives.Simulation results show that this algorithm possesses higher energy usage and longer survival time than those of LEACH.
