Distributed Caching via Rewarding: An Incentive Scheme Design in P2P-VoD Systems

Weijie Wu, Richard T. B. Ma, John C. S. Lui
2014 IEEE Transactions on Parallel and Distributed Systems  
Peer-to-peer (P2P) systems rely on peers' cooperation to provide a more robust and scalable service as compared to the traditional client-server architecture.  ...  Content providers of P2P-VoD services want to incentivize peers to do so and alleviate the workload of the content server.  ...  Users do not always stay in the system, and our model only focuses on those currently online peers. Given any time, some peers have just rejoined the system after disconnecting for some period.  ...
