摘要

云游戏系统在云中托管游戏,而游戏播放和视图则以编码视频帧的形式流式传输到玩家的终端。为了解决实时游戏视频传输的高带宽问题,我们提出了一种cloudlet辅助的多人云游戏系统,以鼓励合作视频共享,该系统利用同一人群中多个玩家通过辅助自组织网络玩同一游戏时视频帧的相似性。在本文中,我们对所提出的系统进行了详细的建模,包括视频帧之间的相关性、终端设备的移动性以及不同玩家的网络服务质量的多样性。通过必要的数学公式,我们研究了参与者在合作共享模式方面的行为,以从用户体验质量的角度优化系统性能。此外,还提出了启发式算法来降低计算复杂度。实证研究和跟踪驱动的仿真结果说明了移动性对系统性能的影响,并表明与现有平台相比,所提出的解决方案能够提供更好的体验质量。

Quality-of-Experience Optimization for a Cloud Gaming System With Ad Hoc Cloudlet Assistance
Cloud gaming systems host the game in the cloud, while Gameplays and views are streamed to the players' terminals in the form of encoded video frames. To address the high-bandwidth issue of real-time gaming video transmission, we have proposed a cloudlet-assisted multiplayer cloud gaming system to encourage cooperative video sharing, which exploits the similarities of video frames among multiple players in the same crowd playing the same game via a secondary ad hoc network. In this paper, we provide a detailed modeling of the proposed system, including the correlation between video frames, mobility of terminal devices, and diversity of network quality of service for distinct players. With necessary mathematical formulations, we study the players' behaviors regarding the cooperative sharing patterns to optimize the system performance in terms of the quality of users' experience. Also, heuristic algorithms are proposed to reduce the computational complexity. Empirical study and trace-driven simulation results illustrate the impact of mobility on the system performance and show that the proposed solution is able to provide better quality of experience compared with the existing platform.
