Multi-source mobile video streaming with proactive caching and D2D communication

Abstract

We present testbed experiments of multi-source mobile video streaming that jointly exploits mobility and throughput prediction to prefetch video data in caches located at hotspots that the mobile will encounter and device-to-device (D2D) communication to opportunistically obtain parts of a video from neighboring mobile devices. A contribution of this paper includes a procedure to efficiently utilize multirate Wi-Fi links, which can be legacy Wi-Fi hotspot links and device-to-device links using Wi-Fi direct.
