摘要
基于无线传感器网络中路由协议高效合理利用能量的要求,提出一种基于剩余能量预测的地理位置路由(EPGR,energy prediction and geographical routing)算法。算法通过建立传感器网络节点运作模型,及相邻节点剩余能量预测机制,优化路由选择。仿真和分析表明,EPGR算法能够有效地优化数据传输路径,均衡传感器网络节点的能量消耗,延长网络寿命。
On the basis of using the energy more effectively in the wireless sensor networks protocol, an energy-prediction-based geographical routing algorithm was designed. Constructing the running model of sensor nodes, predicting the remaining energy of its neighbor nodes, the routing selection was optimized. The result of simulation output and analysis shows that the EPGR could optimize the routing of data transferring, balance the energy consuming of sensor nodes, prolong the network survival.
