| 摘 要： | 未来的无线传感网将由大量密集部署的传感节点组成,这些节点采用电池供电从而能量有限而且补充能量很困难,因此需要研究能量高效的路由协议。利用超宽带(ultrawideband:UWB)精确的定位性能,可以获得传感网中各个节点的位置信息。论文提出了一种新的基于位置的节能超宽带无线传感网路由协议。该协议在从汇聚节点到事件区域的引入节点间不仅使用最小耗能路径而且也经常使用一些次优路径。仿真实验表明论文所提出的协议比GEAR具有更好的节能性。

| Abstract: | Future wireless sensor networks will be composed of a large number of densely deployed sensors.Batteries supply the energy of these nodes,thus energy is very limited and it is difficult to replenish energy.Consequently the energy efficiency muting protocol should be studied.Because of the high precision positioning capability of UWB,the location information of these nodes is obtained accordingly.In this paper,a novel energy efficient routing protocol based on location information for UWB wireless sensor network is proposed.The proposed protocol uses sub-optimal paths occasionally besides the minimum energy path from the sink to the guidance nodes of target region.The simulation results show that the proposed protocol in this paper has better energy efficiency than GEAR. |
