摘要
LEACH是一种将整个网络的能量负载平均分配到每个节点,从而降低能耗、延长网络生命周期的低功耗自适应分簇聚类路由协议。针对组网过程中存在簇头分布不均及其选取方法不足的问题,提出了基于LEACH簇头选择机制的改进算法,该算法利用等角度分区避免簇头分布不均的问题,根据簇内各节点剩余能量决定簇头的选取。仿真结果表明,改进后的算法具有更高的能量使用率和更长的生存时间。
LEACH is a low energy lost self-adapt delaminating route protocol. It allocates the whole network＇s energy load to each node averagely in order to reduce the energy lost and prolong the network life cycle. To solve the problem of cluster-head odds dis- tribution and shortage of selection method, an improvement algorithm was proposed. The algorithm partitions with equal angle to avoid cluster-head odds distribution. It selects cluster-head according to each node＇s remain energy in cluster. Simulation results have shown that the improved algorithm has higher energy use efficiency and longer survival time.
