P2P incentive model for QoS based streaming systems

P2P streaming today is one of the most challenging techniques to deliver real-time streaming on the Internet. Incentive mechanisms make a crucial part of the P2P algorithms in order to avoid uncooperative and eliminate malicious behavior. In this paper we present a monetary incentive mechanism based on the taxation incentive schemes. We use a model of a P2P streaming service to apply the idea and validate the quantitative effect on both the users' and the provider's welfare in the system. A billing model based on QoS levels for the perceived video that offers a remuneration inventive for the cooperative users, contributes to the P2P streaming because of the two main reasons: increases provider's welfare in terms of monetary benefit and saves infrastructure cost; increases users' welfare in terms of increased cooperation and motivation to participate in the streaming.
