摘要：Conventional TV viewing via cable is evolving to Satellite, IPTV and P2PTV based systems. Commercial peer-to-peer systems like Zattoo, Joost are some reputed systems for P2P live streaming. When most content is live or not, file transfer is better in broadcast based systems. But as the volume of interesting content soars, Internet scale search and delivery beats any local services which are the driving force behind P2P Streaming Services. Previously for performance improvement in such systems receiver-based peer-division multiplexing engine involving repeater nodes to deliver live streaming content on a P2P network was developed. But repeater nodes implementation can only be handled by commercial systems like Zattoo. In a free P2P Streaming Systems perspective, this approach is not cost effective and hence presence of intermediate peers is used for efficient content delivery since huge traffic is the backbone for P2P systems. But the performance of these systems is hampered with the presence of free riders (selfish peers). So we propose to use a new mechanism based on supervision Game, and formulate a mixed Nash equilibrium strategy adopting the supervision game. A balanced supervision cost and peer participation income model is analyzed and implemented along with a limited number of repeater nodes from earlier approaches for an optimized performance in a live free P2P streaming systems.
