摘要 分析了无线传感器网络中地理位置路由协议GEAR的特性,针对该协议在数据传输过程中的能耗问题本文提出了一种改进方案,通过改变节点的状态以及对节点采集的数据进行数据融合,避免了无谓的能量损失。通过NS2仿真工具进行验证,改进后的GEAR算法的平均能量消耗降低了百分之十左右。 The characteristic of the geographical routing protocol GEAR in wireless sensor network is analyzed.In this paper,an improved method in energy consumption of GEAR protocol is proposed,by changing the states of nodes and aggregating the collection data,to avoid unnecessary energy loss.The simulation result indicates that the improved GEAR algorithm consumes energy about ten percent less than before.
