Abstract: In the Internet of vehicles, vehicles can download file data from the Road Side Units(RSUs) through wireless communication. However, the volume of data that vehicles can download is significantly influenced by the high mobility of the vehicles, the large distance between deployed RSUs and the limited transmission range. In this regard, a collaborative data distribution scheme is proposed. This scheme makes full use of the resource availability of the two-way vehicles and RSUs to assist the target vehicle in downloading data, so that the target vehicles can still obtain the required file data in the Dark Areas(DAs) beyond the coverage of RSUs. Moreover, considering the impact of the competitive access and transmission of resource nodes, and forwarding completion time on data transmission, a theoretical analysis framework is established to illustrate the data transmission process. Simulation results show that compared with the same direction assisted download and reverse assisted download mechanism, this scheme can increase the volume of data that target vehicles can download, reduce the impact of data transmission interruption in DAs, and improve the utilization rate of DAs.
