Abstract
Vehicular Ad-hoc NETworks (VANETs) promise a wide scope of multimedia services ranging from security and traffic announcements to entertainment and advertising videos. However, VANETs have a dynamic network topology with short contact time, decreasing the Quality of Experience (QoE) of transmitted videos due to frequent disconnections in the communication between neighbours vehicle. Those disconnections cause communication flaws and delays, increasing the packet loss during video transmissions. To cope with this, neighbor vehicles moving on the same direction and wishing to cooperate could form a platoon to disseminate live videos. In this paper, we introduce a platoon protocol based on game theory for video dissemination with QoE support, called P2V. The proposed protocol provides cooperation between neighbor vehicles to establish a platoon by taking into account vehicles direction, speed, and distance, where P2V provides a reward (money or coupon) for vehicles participating in the platoon. Simulation results confirm the efficiency of the P2V protocol to ensure video transmission with high QoE support compared to BLR and XLinGO protocols.
