基于电池电量感知的移动流媒体QoE优化策略

Power-Aware Video QoE Optimization Strategy for Mobile Video Streaming

为了提升移动流媒体应用用户的体验质量(QoE),提出了基于剩余电量的用户QoE模型(PSQM),模型参数包括剩余电量、初始延迟、暂停事件、切换事件.在PSQM基础上,提出了基于移动设备剩余电量和网络环境的码率控制策略(PBCS),避免了客户端不断请求高质量视频片段而不考虑设备剩余电量而影响用户QoE的问题.在移动设备不同电量状态下,PBCS能够实现视频质量和电量的权衡,提高用户QoE.

In order to improve the quality of experience(QoE)of mobile streaming media application users,the power state QoE model(PSQM)based on remained power is proposed.The model parameters include remaining power,initial delay,pause event,and swithing event.Based on PSQM,the Power-aware Bitrate control strategy(PBCS)based on the remained power of the mobile device and the network environment is proposed,which avoids the problem that the client continuously requests high-quality video segments without considering the remained power of the device and affects the user QoE.PBCS can achieve the trade-off between video quality and power,and improve user QoE.
