ARCIM: An Absolute and Relative Contribution based Incentive Mechanism for P2P Live Streaming System

摘要：

P2P live streaming system suffers immensely from free-riding, and researchers develop many approaches to overcome it. However, most studies neglect the role of peers relative contribution which is the ratio of peers actually contribution to its physical capacity, and lead to unfairly resource sharing for low capacity peers and sparing bandwidth not service to others for high capacity peers. To address such problems, we propose a novel incentive mechanism called ARCIM which specify resource-rich peer to subsidize resource-poor peers. We first develop a new method to compute peers contribution score by considering peers absolute and relative contribution. Then we design a service policy based on contribution score to provide incentive-based neighbor selection and chunk request servicing. To maintain good streaming quality, we also propose an online quality feedback mechanism which encourages peers to adaptively reconfigure their upload rate. Simulation results show our mechanism has the superiority in terms of fairness, efficiency and incentive, and outperforms state-of-the-art approaches.
