Incentive Cooperation in Peer to Peer Video Streaming Using Cooperative Game

Nowadays, looking to expand Video streaming systems on peer to peer networks and benefiting from partnership resources, an inexpensive platform for distributed computing, storing and sharing of data is provided which is scalable, accessible, fault-tolerant and robust. In the meantime, the research on Multimedia social networks is emerging and users behaviors as well as their dynamic impacts on multimedia systems have been analyzed. Since participation in peer to peer systems is voluntary and also resources are highly variable and unpredictable in systems, most of such systems are merely a consumer. Thus, these peers either have very little cooperation or have no cooperation with the systems which are generally named free riders .In this paper a proposed approach has been presented in order to motivate a cooperation in video streaming in peer to peer networks using a cooperative games model in which, free rider operators are granted a privilege based on Shapley value according to Incentive mechanism by just benefit distribution resulting from cooperation between mutual peers to provide a unique opportunity for further participation between the peers. Benefit functions in a cooperative game for resource sharing exchanges are in accordance with principle of aggregation of cooperative games and provide greater fame for players by cooperating in bigger integrations. Thus, greater efficiency in the system can be achieved by a general integration resulting from cooperation among all peers
