摘    要:LEACH是针对无线传感器网络设计的低功耗自适应分簇聚类路由算法,与一般的平面多跳路由算法相比,LEACH算法可以将网络生命周期延长15%。但是,靠近汇聚节点的簇头节点由于转发大量数据而导致自身能量消耗过快且节点易失效,从而造成网络分割,形成"热区"的问题,提出了一种新颖的基于分区能耗均衡的多跳非均匀分簇算法(CEUC)。改进后的算法采用固定分簇的方式;形成的簇是不均匀簇,即靠近Sink节点的簇的半径较大,而远离Sink节点的簇的半径较小;簇首选择的依据是节点的剩余能量。仿真实验结果表明,该路由协议有效地平衡了无线传感器网络的节点能耗,延长了网络的存活时间。

关 键 词:无线传感网络  路由算法  非均匀分簇  LEACH

Abstract:LEACH is a low energy adaptive clustering hierarchy algorithm for wireless sensor networks,it can prolong the lifetime of the networks by fifteen percent.But,Employing clustering techniques in routing protocols can improve the scalability of wireless sensor networks.To solve thehotspotproblem that is caused by the cluster heads close to the sink,which are burdened with heavy relay traffic via multi-hop communication and tend to die earlier and that leads to the network being partitioned,a novel cell energy ...
Keywords:wireless sensor networks  routing algorithm  unequal clustering  LEACH
