  Video services in vehicular networks play a significant role in our daily
traveling. In this paper, we propose a cooperative communication scheme to
facilitate video data transmission, utilizing the mobility of vehicles and the
cooperation among infrastructure and vehicles. To improve the video quality of
experience (QoE), i.e., reduce the interruption ratio, quality variation and
improve the playback quality, we design a Back Compensation (BC) video
transmission strategy with the knowledge of vehicle status information. In
addition, we analyze the throughput with one-hop and target-cluster-based
cooperation schemes and obtain their closed-form expressions, respectively,
which is useful for video encoding design in the central server. Simulation
results demonstrate that the proposed approach can improve the video
performance significantly and verify the accuracy of our analytical results.
