Mobility-aware DASH for cost-optimal mobile multimedia streaming services

For multimedia streaming in mobile environments, video bitrate should be carefully determined and different channel quality and pricing in heterogeneous wireless networks (e.g., cellular and WiFi networks) need to be considered. In this work, we propose a new bitrate adaptation (BA) technique called mobility-aware dynamic adaptive streaming over HTTP (MDASH), in which a cellular data usage is minimized through a Markov Decision Process (MDP) framework. Preliminary simulation results are shown that MDASH can reduce 23% of the cellular data usage without any playback interruptions while minimizing the temporal variations in the video quality.
