Abstract:

Vehicular Ad Hoc network is a self-organized inter-vehicle communication network with an open structure. As the relationship between wireless communications technology and transportation industry becomes ever closer,VANET is developed actively. On the basis of presenting the concept and developing process of VANET,this paper makes a survey on the key techniques of VANET. Firstly,this paper introduces the network model,main features and system architecture of VANET,and then discusses the research contents and current situations of physical layer,MAC layer,routing protocols and application layer in detail. Finally,the research directions and applications in the future are prospected.

Key words: vehicular ad hoc network, vehicle safety, inter-vehicle communication, wireless access, routing protocol
