Abstract：Vehicular Ad Hoc Network(VANET) is considered as a special application of Mobile Ad Hoc Networks(MANETs) in road traffic, which can autonomously organize networks without infrastructure. VANETs enable vehicles on the road to communicate with each other and with road infrastructure. However, due to the highly dynamic topology in VANETs, several routing protocols in mobile ad-hoc wireless networks are not very suitable for VANETs networks. Therefore,we propose a routing algorithm which is based on the congestion game. It provide the optimal Internet access path by game theory. The simulation results show that the proposed routing algorithm has better feasibility and effectiveness for communicating VANETs.
