Dynamic Adaptive Streaming over HTTP with Buffer Based Opportunistic Control of Energy Communication Mode

摘要: These days, streaming users are using ABR (Adaptive Bitrate) technique services by requesting the most adequate video rate selectively based on their own channel states. Most related adaptation techniques only focused real-time bitrate adaptations state, and misses energy limited characteristics that come from a mobile device's battery dependence. In other words, important accompanying consumption not being considered causes dissatisfaction over services. this paper, we propose efficient prefetching dynamic adaptive techniques, which saves unnecessary consumed while providing rates of same performance. Our scheme continuously turns off modules with enough in buffer case opposite situation to save energy. Through performance evaluation, study's proposed is 60% better than previous work at global average download speed.
