| 摘 要： | 作为移动Ad Hoc网络具体应用之一的车载Ad Hoc网络具有许多自身特征,如车辆节点处于十字路口时存在许多等待绿灯的静止节点以及通行速度相对缓慢的通行节点。在考虑了上述特征之后,提出了一种适用于车载Ad Hoc网络的新的位置服务设计方案,该设计方案将位置服务与基于位置的路由协议如无状态路由协议GPSR进行融合。在城市场景下的仿真结果表明:通过与GLS和HLS相比,ILSV获得相当高的查询成功率并具有较优的可缩放性。

| Abstract: | The urban vehicular Ad Hoc network has many features such as driven-slowly vehicular and many stopped vehicular when vehicular travels to the intersections.Taking the aforementioned features into account when designing the location service,we proposed a general design of location services for urban vehicular Ad Hoc networks,which was integrated into geographic routing protocols such as stateless routing GPSR.We implemented the location service under network simulation platform NS2 and provided an extensive simulation in a wide of urban scenarios.Simulation results show that ILSV(Intersection Location Service for VANET) achieves good results in terms of query success ratios and remarkable scalability compared with GLS and HLS. |
