Study of the Feasibility of VANET and its Routing Protocols

VANET is a special case of MANET, and will play an important role in city road traffic control. The application of VANET to city road traffic control was studied. The feasibility of VANET was justified, the city section mobility model was appended in NS2, the network model of VANET was established, the simulation scene was compiled, the performances of DSDV, DSR, two classical routing protocols of MANET, and a novel routing algorithm MUDOR, were simulated in VANET and analyzed, and conclusions that reactive routing protocols are more suitable for VANET than proactive routing protocols and MUDOR outperforms DSR with respect to stability of routes were derived. The results have some value in the research and application of VANET to traffic control.
