摘要
LEACH协议是无线传感器网络协议中的经典协议,该协议对簇首的阈值设置采取随机方式。改进了LEACH算法簇首阈值的设置方式,除考虑随机性以外,增加了剩余能量因素的考虑,并且剩余能量对阈值的影响根据均方值的大小自适应变化。利用通用的计算机仿真平台NS2对经典LEACH算法和新算法进行仿真比较,结果表明,改进后的协议至少能够延长网络生存周期的27.5%,。
LEACH protocol is a classical protocol in wireless sensor network protocols.In this paper,the selection of clusterhead in LEACH algorithm was improved.Random threshold,remain energy and mean square value of remain energywere synthetically considered for cluster head selection.LEACH and new algorithm were simulated by a general simulationplatform NS2.Results showed that the improved protocol could prolong the surviving period of network at least by 27.5%,.
