Abstract: 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.
