Abstract:A VANET-CELLULAR integrated network architecture is proposed to ensure efficient data exchanging for various applications in Vehicular Ad-hoc NETwork(VANETs). In this architecture, vehicles are dynamically clustered by related metrics, and those vehicles conformed to the context-aware requirement are selected as mobile gateway to link the 3GPP networks. A distributed game theoretic approach is adopted to stimulate vehicles to cooperate with their neighbors, and the overall performance of communication is improved by evolutionarily maximizing each vehicle’s own utility. The simulation results show that this approach works efficiently in selection of the minimal mobile gateways in VANETs.
