Study of VOD streaming on BitTorrent

Nowadays, the Peer-to-Peer (P2P) Video-on-Demand (VOD) systems knows a huge success for several reasons: a) each peer is both server and client leading to scalable system, b) it is not necessary to build and maintain infrastructures. BitTorrent is the most popular P2P file sharing protocols due to its effectiveness in the delivery of content. Thus, many VoD protocols have been proposed based on it. They investigate new ways for pieces and neighbor peers selections to assure the tight displaying time deadlines of video frames. In this paper, we present an up-to-date literature review of the main P2P VoD works based on the BitTorrent protocol. Furthermore, we propose a taxonomy of these works considering the pieces and the peers selection algorithms criterions.
