The communication quality of a vehicular network is confronted with great challenges due to a surge in vehicle numbers, as well as the high mobility of vehicles on the road. Network coding technologies can improve network performance in terms of higher throughput, reliability, and robustness. In this paper, we generally consider the characteristics of vehicular communication, network coding, and cooperative communication and study the methods of outage probability analysis in a vehicular cooperative network. Based on this, we propose a novel mobile dynamic relay selection strategy with network coding and also derive the expressions of diversity gain and channel capacity. Finally, we conduct simulation experiments with different scenarios to verify the proposed strategy. The theoretical analysis and simulation results show that the proposed relay selection strategy can effectively reduce the outage probability, improve the system diversity gain, and expand the system capacity.
