移动的设备上的视频流传输需要在用户的体验质量（QoE）和能耗之间进行平衡。由于视频数据量很大，下载、处理和播放每个视频片段都需要大量的电池电量。然而，为了追求能源效率，视频质量可能会受到严重影响。在平衡这两个目标，我们的研究采用了先进的能源模型，处理器时钟频率，缓冲区管理，网络质量感知下载。此外，多用户系统提出了独特的挑战，在优化给定的竞争网络资源。我们的算法考虑了这些波动和跨多个用户和多个小区的并发需求。提供了LTE网络中的当前应用和未来在5G系统中实现的基础。
Video streaming on mobile devices necessitates a balance between a users' Quality of Experience (QoE) and energy consumption. Given large data sizes from video, extensive amounts of battery power are required for downloading, processing, and playing each video segment. However, video quality may suffer drastically in an effort to pursue energy efficiency. In balancing these two objectives, our research incorporates advanced energy models, processor clock rates, buffer management, and network quality aware downloading. Furthermore, multi-user systems present unique challenges in optimization given competition for network resources. Our algorithm accounts for these fluctuations and concurrent demands across both many users and many cells. Present application in LTE networks and foundations for future implementation in 5G systems are provided.
