摘要：

the potential power to enhance the application experience associated with traffic safety, management and infotainment. The experience of user is seriously affected by the quality of the video display. Therefore, Quality of Experience (QoE) enhancement for video delivery in VANETs is an important issue. However, the high mobility and dynamic nature of VANETs cause the dynamic topology which poses a significant challenge for video delivery. In this paper, we propose a useroriented cluster-based solution called CDOV (Cluster and Dynamic Overlay based video delivery over VANETs), which combines the novel clustering algorithm and the dynamic overlay structure into a novel structure. Simulation results show that CDOV scheme for video delivery over VANETs significantly reduces the startup delay and increases the delivery rate compared with the gossiping-based scheme.
