随着移动的用户数量的增加，利用通信中的经济性已经被设想为提高网络性能的新范例。然而，诸如激励卸载设备和提高最终用户体验质量（QoE）等问题仍然是开放的挑战。所提出的算法协议的理念在于鼓励终端用户从邻居（卸载用户）接收多媒体数据，并且通过这样做，通过利用较短的通信距离来最大化他们的QoE。该协议还通过在卸载用户和终端用户之间建立缓存委托通信，以降低网络流量拥塞，提高利润。通过将服务提供商、卸载用户和最终用户之间的交互制定为一个博弈，实现了所提出的博弈论算法协议的稳定性。一个算法已经开发出来，以确定纳什均衡解的游戏，最大限度地提高所有各方的效用。使用H.265编码的多媒体数据进行的仿真研究表明，终端用户的QoE和减少网络拥塞的显着提高。
With increasing number of mobile users, leveraging economics in communications has been envisioned as a new paradigm to boost the network performance. However, the issues such as incentivizing offloading devices and improving end-user Quality of Experience (QoE) are still open challenges. The philosophy of the proposed algorithmic protocol lies in encouraging end-users to scavenge multimedia data from the neighbors (offloading users), and by doing so, maximize their QoE by taking advantage of shorter communication distance. The protocol also facilitates the wireless carriers to lower the network traffic congestion and to improve profits by setting up cache delegation communication among the offloading users and end-user for a nominal commission fee. Steadiness of the proposed game theoretic algorithmic protocol has been achieved by formulating the interaction between the service provider, offloading user and the end-user as a game. An algorithm has been developed to determine the Nash Equilibrium solution of the game which maximizes the utilities of all the parties. Simulation studies conducted using H.265 encoded multimedia data indicate a significance raise in end-user QoE and decrease in network congestion.
