Incentive mechanism for service differentiation in P2P networks
Junghwa Shin, Taehoon Kim, Sungwoo Tak · 2009
P2P (Peer-to-Peer) networks are self-organizing networks and rely on voluntary contribution from individual peers. Peers can easily access information without contributing any information or service to P2P networks. This leads to the well known free-riding problem. In order to encourage the cooperation of peers, there needs to be an incentive mechanism that rewards cooperation and punishes free riding. In this paper, we propose an incentive mechanism, called P2PIM (P2P Incentive Mechanism for Service Differentiation), which computes the contribution by monitoring the peer's behavior and provides the differentiated service according to the peer's contribution. Our simulation results show the efficiency and stability of proposed incentive mechanism.
