一种响应型无线传感器网络路由算法

Reaction Wireless Sensor Network Routing Algorithm

提出一种节能型无线传感器网络路由算法——TEENNEW。该算法利用能量模型确定了最优簇头数,在簇头选取阶段考虑了节点剩余能量;在数据传输阶段,该算法根据距离和能量建立簇头与基站之间的多跳通信路径。与传统的TEEN协议相比,TEENNEW算法延长了网络的生命周期,有效均衡了节点能耗。

In this paper,an energy-efficient wireless sensor network routing algorithm called TEENNEW is proposed.This algorithm uses the energy model to determine the optimal number of cluster head and considers the nodes＇ residual energy in cluster heads selection stage.In data transmission phase,the algorithm according to the distance and the energy establishes a multi-hop communication path between the cluster head and base station.Compared with the TEEN protocol,the algorithm can effectively prolong the lifetime of the networks and reduce energy consumption.
