摘要
通过分析传统的基于地理位置的路由协议在比较困难的环境下很难取得理想的高可靠性、低负载的问题,提出了一种自适应的贪婪地理路由协议。该协议总结了对网络移动性能造成影响的两个因素,即节点移动速度和停留时间,自动调整节点发送信标的周期和选择下一跳的方案,从而达到减少负载和增加转发成功率的目的。仿真结果显示,该协议在两方面都取得了较好的效果。
The paper analyzed the performance deficiency of traditional routing protocal basing on the actual geographical setting,and proposed a novel adaptive greedy geographical routing protocol. Through analyzing two factors affecting networks mobility——the moving speed and the pause time of nodes,the protocal adjusted the beacons sending cycle and selected the better next hop to achieve the goals of reducing overload and increasing delivery success ratio. Simulation results show that the protocol can acquire better effect compared to GPSR ( greedy perimeter stateless routing) .
