Comparative study of VANET routing protocols

Vehicular Ad-hoc network is a fast mobile broadband wireless network, which can provide a variety security applications and business applications of for vehicles such as traffic safety management, accident alarm, auxiliary driving, Internet information services. Routing is one of the key technologies of vehicle network, so this paper studies the VANET routing protocol by using literature comparative study method. The routing protocol based on topology, the routing protocol based on geographic location, the routing protocol based on the cluster, the routing protocol based on opportunity strategy and the routing protocols based on security are compared respectively.
