MP-DASH: Adaptive Video Streaming Over Preference-Aware Multipath

摘要: Compared with using only a single wireless path such as WiFi, leveraging multipath (e.g., WiFi and cellular) can dramatically improve users' quality of experience (QoE) for mobile video streaming. However, Multipath TCP (MPTCP), the de-facto solution, lacks support to prioritize one over another. When applied streaming, it may cause undesired network usage substantial over-utilization metered cellular link. In this paper, we propose MP-DASH, framework streaming awareness interface preferences from users. The basic idea behind MP-DASH is strategically schedule chunks' delivery thus satisfy user preferences. work wide range off-the-shelf rate adaptation algorithms very small changes. Our extensive field studies at 33 locations in three U.S. states suggest that effective: reduce by up 99% radio energy consumption 85% negligible degradation QoE, compared MPTCP.
