一种基于网格的无线传感器网络动态分簇路由协议

A Dynamic Clustering Routing Protocol for Grid-Based Wireless Sensor Networks

无线传感器网络是一种资源受限的网络,特别是在供能方面,为提高网络生存时间,提出了一种基于网格的无线传感器网络动态分簇路由协议,虚拟网格可以根据局部的信息动态的调整簇的大小,达到节省能量的目的;采用唯一簇头选举法(unique clusterhead election method)产生簇头,确保每个虚拟网格内只有一个簇头,并在恰当的时候才更换簇头;仿真实验和分析表明,该协议有效地平衡了整个网络的能量消耗,并显著地延长了网络的生存时间。

Wireless sensor networks （WSN） are severely resource constrained, especially in the aspect of power supply. To prolong the lifetime of wireless sensor networks （WSN）, A dynamic clustering routing protocol for grid--based wireless sensor networks was proposed. Virtual grid could dynamic adjust the size of cluster based on local case for the purpose of saving energy. And unique cluster head election method elect cluster head, which ensure each grid have only one cluster head. Simulation results show this routing protocol effectively balances the energy consumption of the network and significantly prolongs the lifetime of network.
