Abstract

In recent years, mobile video streaming is gaining overwhelming popularity and occupying an increasing proportion in mobile data traffic. Video streaming is sensitive to viewing interruptions and hungry for energy, so it is of great significance to mitigate the effect of viewing interruptions and reduce energy cost while enjoying video streaming services in cellular networks. In this paper, considering both channel quality and user buffer state, we propose a QoE aware and energy efficient online scheduling scheme based on Lyapunov optimization framework. In the scheme, a novel method by dynamically controlling the weighting value of energy consumption is introduced to obtain more energy saving and guarantee QoE performance. Simulation results demonstrate that our proposed scheme can reduce both rebuffering delay and energy consumption compared with the state-of-art method.
