Abstract

This letter proposes a novel rate adaptation framework for dynamic adaptive streaming where three factors-available bandwidth, buffer state, and residual battery status, jointly determine the bit rate selected. We model the rate adaptation problem as a Markov Decision Process (MDP) with a goal to optimize video streaming experience as measured by video playback quality and buffer occupancy. Using simulation study, we show that our approach, termed as 3B-ARA, reduces rebuffering rate by over 20% while delivering a comparable average video rate and maintaining an average of 93% buffer occupancy as compared to other existing rate adaptation approaches.
