能量自适应的无线传感器网络分簇路由协议

为有效解决无线传感器网络中的"热区"问题,提出了一种能量自适应的非均匀分簇路由协议.协议采取非均匀的分簇结构,使靠近基站的簇范围减小到合理的范围,即在靠近基站的区域内,每个簇由较少的无线传感器节点构成,这些节点的主要工作是负责转发其它簇的信息,从而有效减少其能量消耗速率.同时,协议在通信路由的过程中还综合考虑了簇头与中转节点的距离以及中转节点的能量消耗率.实验结果表明,该协议有效解决了"热区"问题,并且延长了无线传感器网络的生命周期.

Energy adaptive cluster-based routing protocol for wireless sensor networks

Aiming at the hot spot problem in wireless sensor networks,an energy adaptive and uneven cluster-based routing protocol is proposed.In the protocol,a kind of uneven cluster structure is adopted,which decreased the cluster range near the base station into a proper scope.Clusters in the area near to the base station are made up of nodes with a less amount of wireless sensors.The nodes are mainly in charge of forwarding messages from other clusters,so that the energy consumption is reduced significantly.At the...
