摘要: 由于车载自组织网络(Vehicular ad hoc networks)具有特殊的节点类型和信道特性,采用传统Ad hoc网络路由协议无法取得满意的性能。实现高速可靠的数据传输速率,需要研究新兴的路由算法。基于贪婪算法的地理位置辅助路由是目前VANET路由的主流思路。主要研究基于地理位置的路由协议,对GPSR(Greedy Perimeter Stateless Routing)协议进行改进,引入了向量的概念来改进 GPSR路由协议的贪婪转发模式,即在选择下一跳节点时不仅要考虑到目的节点的距离,还要考虑城市环境中的十字路口节点,并增加了预测模式来预测车辆在十字路口的移动以提高路由协议的效率。

Abstract: As Vehicular ad hoc networks has a special node type and channel characteristics,using the traditional Ad hoc network routing protocol can not achieve satisfactory performance.In order to realize high speed and reliable data transmission rate,it is needed to study the emerging routing algorithms.Geographical location aided routing based on greedy algorithm is the mainstream of VANET routing.This paper mainly studied the routing protocol based on the geo-graphic location, improved GPSR(Greedy Perimeter Stateless Routing) routing protocol.Introduced the concept of vectors to improve the routing protocol GPSR greedy forwarding mode,i.e. the choice of the next hop node considers not only the distance from the destination node but also the urban environment crossroads node.Moreover,added predictive models to predict the movement of vehicles at intersections and improve the efficiency of routing protocols.

Key words: VANET(Vehicular ad hoc networks),Road topological,GPSR(Greedy perimeter stateless routing)
