A Statistical Approach to Smooth Video Quality Adaptation in IEEE 802.11 Wireless LANs

Recently, MIT Adaptive Streaming is a de facto video delivery mechanism which adapts video quality to user specific circumstance for better QoE. In this paper, we apply a statistical method to bandwidth estimation procedures to stabilize video quality adaptation in highly dynamic networks, e.g., Will. Simulation results reveal that our proposal can achieve a smaller variation of video quality and less quality switch events by smoothing estimated bandwidth while keeping high utilization of wireless capacity, i.e, the same average bit rate as other schemes.
