Mtv: Mobile Bittorrent Video Sharing Using Harmonized Lte And Wifi Coexistence

With the rapid development of streaming media, communications between Device-to-Device is becoming a magnetic solution to improve the performance of cellular network. Although numerous papers have been published in the past, most of them just focus on novel description but ignore the classical theory to be innovated. In this paper, inspired by BitTorrent protocol, we propose a dynamic d2d system for video sharing using cellular interface and WiFi Direct technology. In our scenario, we consider a cluster of users within proximity of each other viewing the same video, and traffic of cellular will be offloaded onto WiFi Direct. In this paper, we implement a BitTorrent similar system on mobile devices to share video named MTV, which constructs a D2D network and converts the transmission between users from previous cellular interface to wifi interface. Benefiting from video sharing and properties of BitTorrent, our system will not only bring improvements on downloading rate and reduction on traffic consumption, but also support dynamic joining and leaving which were rarely mentioned in previous work. And we provide several experimental scenes to demonstrate the advantages of our proposed system on aspect of speed, traffic and dynamic adaption.
