A distributed mechanism for dynamic resource trading in cooperative mobile video streaming

With the emergence of high speed mobile Internet access in smart devices, providing a specific quality of service (QoS) for video delivery is a challenging task due to the dynamic nature of the wireless channels. In this paper, we propose an auction based mechanism that facilitates cooperation among mobile nodes, in order to increase the level of QoS satisfaction in the network. In the proposed mechanism, users with excess resources that are surplus to their QoS requirement (sellers) are motivated to provide a relaying service to users with low QoS (buyers), in exchange for monetary compensation. Our mechanism is entirely distributed and does not require a coordination by a centralized auctioneer, which helps to minimize the implementation overhead and allows it to be applied regularly with short period times. The efficiency of the auction mechanism is verified using simulation over a range of typical practical scenarios.
