| 摘 要： | 针对有向带状无线传感器网络中,节点能量受限导致网络存活时间难以保证的问题,提出一种基于时间退避机制与能量效率的地理路由协议(GRBE).以单位能耗传递数据包的有效距离,作为选择下一跳节点的标准,在建立带状网络模型基础上,通过基于时间退避机制选取下游节点,减少了上游节点与下游节点间不必要的通讯和数据传输能量消耗.经模拟对比仿真,新路由协议GRBE网络寿命分别是GEAR的1.96倍、OFEB的1.31倍.

| Abstract: | In order to solve the difficulty in guaranteeing the network lifetime caused by limited node energy in di-rected band-like wireless sensor network,a geographic routing protocol based on time Back-off mechanism and ener-gy efficiency(GRBE)was proposed. The effective distance of transmitting the data packet by the unit energy con-sumption was used as the criterion of selecting the next-hop node.The downstream nodes were selected based on the band-like network model and time Back-off mechanism,thus reducing the unnecessary energy consumption by com-munication and data transmission between the upstream node and the downstream nodes. Simulation comparison demonstrated that the average network lifetime of the new routing protocol GRBE was 1.96 times that of GEAR and 1.31 times that of OFEB. |
