Abstract
Vehicular Ad Hoc Networks (VANETs) allow users, services, and vehicles to share information and will change our life experience with new autonomous driving applications. Multimedia will be one of the core services in VANETs and are becoming a reality in smart environments, ranging from safety and security traffic warnings to live entertainment and advertisement videos. However, VANETs have a dynamic network topology with short contact time, which leads to communication flaws and delays, increasing packet loss, and decreasing the Quality of Experience (QoE) of transmitted videos. To cope with this, neighbor vehicles moving on the same direction and wishing to cooperate should form a platoon, where platoon members act as a relay node to forward video packets in autonomous VANETs. In this article, we introduce a game theory approach for platoon-based driving (GT4P) for video dissemination services in urban and highway VANET scenarios. GT4P encourages the cooperation between neighbor vehicles by offering reward (e.g., money or coupon) for vehicles participating in the platoon. In this sense, GT4P establishes a platoon by taking into account vehicle direction, speed, distance, link quality, and travel path, which reduces the impact of vehicle mobility on the video transmission. Simulation results confirm the efficiency of GT4P for ensuring video transmissions with high QoE support compared to existing platoon-based driving protocols.
Highlights
Vehicular Ad Hoc Networks (VANETs) allow moving vehicles to form self-organized ad hoc networks without the need of permanent infrastructure [1]
Videos delivered by P2V, Bidirectional Stable Communication (BDSC), and Furthest Distance (FD) reduced the structural similarity (SSIM) in 11%, 60% and 48% compared to GT4P, respectively
This article introduced GT4P protocol as a solution to form a platoon based on game theory for video transmission with adequate Quality of Experience (QoE)
Summary
Vehicular Ad Hoc Networks (VANETs) allow moving vehicles to form self-organized ad hoc networks without the need of permanent infrastructure [1]. Platoon-based driving can be encouraged by offering discounts at local markets, free parking lots, free movies, priority for video consumption, and network resources, among other profits [20, 21] In this context, game theory is an effective tool to model and analyze an incentive mechanism and for inactivated nodes (i.e., vehicles) to cooperate [20, 22]. We introduce a game theory approach for platoon-based driving protocol (GT4P) for video transmission over urban and highway VANET scenarios. GT4P considers it a noncooperative game, where cooperative behavior is enforced by means of a rewarding function to give incentive for vehicles participating in the platoon, which is actively collaborating with the video transmission with QoE support.
