| 摘 要： | 能量有限性是无线传感器网络(WSN)的最重要的特性,在网络路由算法中也是优先考虑的一个主要因素。分析了传统LEACH算法的不足,并对一些改进协议的LEACH进行认真研究,在此基础上提出了一种新的LEACH改进协议,仿真结果表明,改进后的协议能均衡节点能耗,提高了负载均衡度,并延长了无线传感器网络的生存时间。

| Abstract: | One important feature of wireless sensor networks is that the energy is limited.This feature is considered to be the main element in routing algorithm of WSN.This paper analyzes the traditional algorithm-LEACH.After researching some related improved protocols of LEACH,we advance a new protocol based on LEACH.The result s of simulation show t hat t he improved routing protocol can balance energy consumption of nodes and prolong t he lifetime of WSN. |
