摘要
针对低功耗自适应集簇分层型协议(Low Energy Adaptive Clustering Hierarchy,LEACH)能量消耗不均和节点过早死亡的问题,提出了LEACH协议的改进方案.该方案考虑了聚簇内节点的能耗、定位和网络服务质量,从簇头的选举算法和数据融合着手,在生存时间、能量消耗、基站数据接收三方面对簇头选举算法进行了分析改进.对改进后的LEACH协议和原LEACH协议进行仿真,仿真结果表明改进后的协议在生存时间上提高了33%,并减少了节点能量消耗和降低了基站接收数据的量.
In order to solve the problems of LEACH（Low Energy Adaptive Clustering Hierarchy）——the energy consumption inequality and node＇s premature death,the paper puts forward an improved algorithm of the LEACH.It is improved in the election of cluster and data fusion algorithm.This study is based on the proposed algorithms for energy efficient wireless sensor networks.The energy efficient schemes for clustering,localization and QoS（Quality of Service） based on congestion estimation are studied.A comparison is made of LEACH protocol with NEW-LEACH protocol in the aspects of energy consumption,life time and nodes data reception.Simulation results show that the improved protocol increases by 33% in survival time and reduces node＇s energy consumption and the data received by the base.
