在本文中，我们提出了一种价格驱动的纳什讨价还价博弈解决方案，以最大化无线多媒体通信中缓存内容优化的体验质量。通过通过设备到设备(D2D)通信利用缓存的多媒体内容和智能媒体定价(SMP)概念，在服务提供商(SP)和终端设备(ED)之间建立了经济-质量平衡。本文的主要贡献如下。首先，根据多媒体包的重要性，提出了一种价格驱动的多媒体资源分配方法，将缓存的多媒体资源分配给卖方EDS。然后，在考虑多媒体包重要性和内容热度的情况下，建立了买卖双方的纳什讨价还价博弈模型。借鉴两人纳什讨价还价博弈模型，通过推导纳什讨价还价解(NBS)，提出了一种多媒体内容的购买-缓存-转售策略。仿真结果表明，在质量驱动的无线多媒体通信中，所提出的SMP缓存分配方法具有较高的效率和公平性，具有较好的帕累托最优性能。
In this paper, we propose a price-driven Nash Bargaining game solution to maximize Quality of Experience (QoE) with cache content optimization in wireless multimedia communications. By leveraging the cached multimedia content and the Smart Media Pricing (SMP) concept through device-to-device (D2D) communications, the economic-quality equilibrium is established between Service Provider (SP) and End Devices (EDs). The contribution of this paper is as follows. First, referring to the importance of multimedia packets, we develop a price-driven method to allocate cached multimedia resource on the seller EDs. Then a Nash Bargaining game is formulated between the seller and buyer EDs considering multimedia packet importance and content popularity. Referring to the two-player Nash Bargaining game theoretic model, a buying-caching-reselling strategy for multimedia content is proposed by deriving the Nash Bargaining Solution (NBS). Simulation results demonstrate that the proposed SMP cache allocation method has high efficiency and fairness in quality-driven wireless multimedia communications, leading to desirable utilities towards Pareto optimality.
