| 摘 要： | 论述了车用自组织网络(vehicular ad hoc network,VANET),认为车辆节点既是网络的终端也是路由器,可以实现自组织和自管理的通信。与一般无线自组织网络相比,车用自组织网络具有节点运动速度快、节点移动受道路拓扑约束和节点数量巨大等特点。路由选择是车用自组织网络成功运行的基础,对此提出了一种基于交通感知的路由协议。该协议由两个部分完成:先动态选择传送数据包需经过的交叉路口;再在两交叉路口之间的路径中根据一种贪婪的策略来选择传送数据的下一跳节点。模拟结果显示,与传统的地理位置路由协议等相比,所提出的协议在数据的传递率和端到端的延时等方面都有较大的提高。

| Abstract: | VANET is self-organized and each node is the terminal node as well as the router.VANET can realize self-organization and self-management,which has some specific attributes that are different from the conventional MANET(mobile ad hoc networks)such as nodes distribution,constrained but high mobility patterns,etc.One of the fundamental components for the success of VANET applications is routing.In our current work,a traffic-aware routing protocol(TAR)suited for city environments was proposed.It consisted of tw... |
