战场环境VANET的AODV和GPSR比较分析

Research of AODV and GPSR Based on VANET Battlefield Environment

VANET的战场环境不同于城市环境,没有交通道路的束缚,结点在运动中表现出更多的随机特征。针对战场环境的随机特性,提出了一种车载自组织网络模型。通过战场区域的车流密度调整车辆行驶的速度,在不同的区域对节点的密度进行比较,通过节点密度的变化调整车辆运行的速度,对不同的运动场景进行了仿真,并比较了AODV和GPSR两种典型的路由协议的参数。仿真结果表明,AODV协议在稀疏区域和快速拓扑变化的情况下性能相对较好,GPSR在结点密度较大的区域表现出良好性能。

Unlike urban scene, the battlefield environment has the features with no traffic bondage. It displays more random feature in VANET. In this paper, a VANET model for battlefield environment has been proposed. According to the traffic density in battlefield area, the speed of the vehicle has been adjusted. Then it compared the parameters of AODV and GPSR routing protocol.Through an analysis of the result, the AODV has better performance in a sparse area or a fast changing topology, and GPSR shows better performance in a larger density area.
