【摘要】 VANET是一种具有高度移动性的无线ad hoc网络,将在公共通信安全和商业运用中扮演重要角色。由于高速变化的拓扑结构和车辆的移动性,传统的MANET(mobile AD hoc network)路由协议无法完全解决车辆网络的这种特殊性问题。该文中,我们提出了基于位置路由的贪婪路由算法,即在传输距离有限范围内,把转发节点到朝着目标方向的边缘节点作为最适合下一跳来转发数据包。仿真结果表明,与现在的VANET路由协议相比,在数据包传输中端到端的传输时延大大减小。更多还原

【Abstract】 VANET is a highly mobile wireless ad hoc networks, and will play an important role in public communication security and commercial use. Due to the high speed change topology and the mobility of vehicles,the traditional MANET(mobile adhoc network) routing protocol can not completely solve the special problem of the vehicle network. In this article, we put forward the greedy routing algorithm based on location routing, namely within the scope of the limited transmission distance,the forwarding nodes toward the direction of the target edge nodes as the most suitable for the next jump to forward packets.The simulation results show that compared with the present VANET routing protocols, that end-to-end delay in Data packets transmission is greatly reduced.更多还原
