中文摘要：
为延长网络生存时间，提出了一种基于网格的无线传感器网络分簇路由协议。整个网络分成若干个虚拟网格，每个虚拟网格形成一个簇，采用唯一簇头选举法产生簇头，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。
英文摘要：
To prolong wireless sensor networks lifetime, a clustering routing protocol for grid-based wireless sensor networks is proposed. Whole network is divided into some virtual grids and sensor nodes in each grid form a cluster respectively, unique cluster head election method is used to elect cluster head. 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.
