Cluster based V2V communications for enhanced QoS of SVC video streaming over vehicular networks

Cooperative vehicle-to-vehicle (V2V) communications for real-time video streaming of scalable video coded (SVC) videos is investigated, and a novel clustering method is proposed. In the proposed method, moving vehicles are grouped into cooperative clusters to enhance the distribution of the video to the cluster members. Within each cluster, vehicles communicate over IEEE 802.11p, whereas the long term evolution (LTE) system is used to send the data over long range cellular links. The simulation results show that the collaborative V2V video streaming method significantly outperforms the non collaborative case.
