Abstract: In order to prolong the lifetime of the Wireless Sensor Network(WSN),a Changing Energy Clustering Routing based algorithm(CECR) is proposed.The main idea of CECR is to divide the WSN field into concentric rings and change the radius of the clusters gradually when the nodes’ energy is decreasing slowly.The simulation results prove the good performance of CECR in large area WSN scenarios.

Key words: wireless sensor network, ring based model, clustering routing, radius of the clusters, lifetime

摘要: 为了提高无线传感网在大区域情形下的能量效率,提出了一种基于能量的分簇路由算法,该算法通过分环的方式实现簇头间的多跳通信,并随着能量的减少逐渐缩小每个环内簇半径的大小来延长网络的生命周期。仿真结果表明,该算法有效地延长了网络的生命周期。
