Abstract
In sports stadia and similar crowded venues, maintaining an acceptable network quality of experience (QoE) becomes a difficult task. Currently, the problem is approached via small cells, distributed antenna systems and high-density WiFi, which are complex and expensive. Hence, we propose a distributed low-cost solution based on user coordination to improve the average QoE without increasing the network capacity. Specifically, fans take turns in disabling their cellular connectivity, such that the connected users utilize the relaxed network to share common match data with the disconnected users via Peer-to-Peer (P2P) connectivity. To eliminate a free-riding behavior, a limited punishment strategy is proposed and shown to yield an approximate subgame-perfect Nash equilibrium. MATLAB simulations demonstrate tangible gains in average QoE when the number of users of the proposed scheme is significant.
