چکیده
We present and evaluate a procedure that utilizes mobility and throughput prediction to prefetch video streaming traffic in integrated cellular and WiFi networks. Our evaluation is based on trace-driven simulation considering empirical measurements and shows how various parameters influence the performance, in terms of the number of paused video frames and the energy efficiency; these parameters include the number of video streams, the mobile, WiFi, and ADSL backhaul throughput, and the number of WiFi hotspots. Also, we assess the procedure’s robustness to time and throughput variability. Finally, we present our initial prototype that implements the proposed approach.

متن کاملAdaptive Mobile Video Streaming and Efficient Social Video Sharing in the Clouds
While demands on video traffic over mobile networks have been souring, the wireless link capacity cannot keep up with the traffic demand. The gap between the traffic demand and the link capacity, along with time-varying link conditions, results in poor service quality of video streaming over mobile networks such as long buffering time and intermittent disruptions. Leveraging the cloud computing...
