An Efficient P2P-based Mobile Social Media Delivery for Real-time MobileCast

With traditional video live streaming technologies, the quality of the video degrades as more viewers tune in. Big viewers need a lot of bandwidth to support them. In this paper, we propose a new algorithm with which mobile user is both capable of broadcasting and watching live video at the same time. It is called MobileCast. MobileCast allows users broadcast their own video in real-time to neighbor mobiles based on peer-to-peer network using BitTorrent protocol technology. With MobileCast, the quality and reliability of the broadcast actually improves every time a new viewer joins, since every new viewer becomes a miniature broadcaster and amplifies the stream. The idea is to use some of the idle sending capacity at the end mobile users. When mobile user captures and sends video in real-time, the mobile device becomes a broadcaster then it can send this video for other mobile devices which again would forward the stream to other mobile, and so on.
