一种基于能量均衡的WSN分簇路由算法

Energy balance-based cluster routing algorithm for Wireless Sensor Network

针对无线传感器网络节点能量有限的特征,在研究现有算法的基础上提出了一种基于能量均衡的分簇路由算法CRAE。新算法在簇首选择时引入了节点剩余能量与邻节点平均能量参数,同时在通信中综合考虑了最小跳数与中转节点的能量问题。实验结果表明,该算法有效均衡了网络能耗,延长了网络生命周期。

In connection with the energy limited features of node in Wireless Sensor Network, this paper pres- ents a cluster routing algorithm CRAE based on energy balance according to the research of existing algo- rithms. The new algorithm introduces the residual energy of node and the average energy parameters of neigh- bor nodes, while considering the minimum hop and the energy issues of transit node in communication. The experiments show that the algorithm can effectively balance the energy consumption and prolong the network li- fetime.
