摘要： 为了提高高动态无线传感器网络的通信性能,提出了一种新的地理路由方案(Efficient Geographic Routing Scheme Based on Location Prediction and Energy Saving,LPESGR)。首先,给出了ESGR节能地理路由算法和GPS与RSSI相结合的节点定位及预测算法；然后,在两个算法的基础上提出了一种基于能源高效性的路由实时搜索算法来搜索能源消耗最小的实际路由；最后,提出了一种新的路由空洞解决方案,该方案避免了传统方案中的不足。除此之外,为提高能量利用率,降低路由中断概率,提出了一种新的基于信号传送距离预测结果的功率实时调整方案。仿真结果表明,所提方案可以有效减小网络能耗并提高数据传输成功率。
