摘　　要：针对现有无线传感器网络中各节点能量消耗不均的缺陷,提出基于网格的二层分簇方案设计能量感知路由协议,在分簇过程中,利用节点位置信息确定簇的大小,通过簇头节点来实现均匀的网络划分。经过理论分析和仿真实验,对该协议的性能进行验证,并与LEACH协议进行比较。结果表明,该协议能够使网络中各节点较均衡地消耗能量,从而延长整个网络的生命周期。For the disadvantage of some nodes energy consumption nonequilibrium nowadays in the Wireless Sensor Network（WSN）,this paper presents the energy aware routing protocol based on the grid 2D cluster.Through the process of cluster,the cluster’s size can be confirmed by nodes’ position.Network partition is equilibrium with the cluster node.By the theoretic analysis and emulator experiments,performance of the protocol is verified and compared with LEACH,result of which shows that this protocol can equally balance the energy consumption of all the nodes,and the lifecycle of wireless network can be prolonged.
