An “S-string” scheme for business-oriented peer-to-peer networks

In this paper we introduce and analyze S-string, a Peer-to-Peer (P2P) payment-based mechanism. S-string enhances the functionality of P2P networks by promoting cooperation among peers, rewarding them to participate in sharing objects, and encouraging them to reduce their downtimes. It also imposes tougher punishment procedures on peers when they do not fulfill their obligations to others. S-string supports the role of media entities by taking into consideration their concerns about the distribution of digital media contents or objects in a lawful and profitable manner. We demonstrate the performance results of our proposed mechanism via simulation.
