Abstract:

In this paper, we study such a scenario: in the network consisting of both V2I and V2V communication, a vehicle is driving on highway, and it is trapped because of various reasons. In order to assist this trapped vehicle to maintain its network communication as possible, we propose an interactive network model and relevant scheme, which expropriates part of communication capabilities of other passing vehicles to assist the trapped vehicle to propagate data in an interactive way. We simulate the MVA model and scheme in NS2 and compare the proposed MVA scheme with DSDV, AODV, DSR routings in the blind area of VANET. The simulation results show that the AODV and DSR routings perform not well in the blind area of VANET. And the proposed MVA scheme achieves higher improvement in the average amount of network flow performance than DSDV routing.
