摘要
为了延长无线传感器网络生命周期,提出一种基于虚拟网格的分簇路由算法RPLG.该算法将监测区域划分为若干虚拟网格,同一网格内节点自组织成簇.根据节点所在网格位置和剩余能量启动计时器选取本地簇首,且簇内成员可以根据局部的信息调整簇的大小,达到节省能量的目的.仿真实验和分析表明:该协议能均衡网络能量,延长网络的生存时间.
In order to extend the network lifetime in wireless sensor network, A Routing Protocol Based On The Location Of Grid In WSN（RPLG） was presented. Whole network is divided into some virtual grids and sensor nodes in each gird form a cluster respectively. The cluster head was chosen by the node＇s location in gird and residual energy. In order to save network energy, cluster members can adjust cluster size according to local information. Simulation results show the proposed routing protocol effectively balances the energy consumption for sensor nodes in wireless sensor networks and significantly prolongs wireless sensor networks lifetime.
