Dynamic Cooperation Enforcement Through Trust-Based Allocation Policies in P2P Systems

In this paper, the authors propose distributed trust-based resource allocation policies to provide fairness in p2p-like systems. According to these policies, the portion of the available resource received by each competing peer depends on his trust/reputation, his resource demands and his request generation rate. The reputation of a peer is quantified and an approach for continuously updating the reputation is proposed such that it reflects the contributions of the peer in the transactions he engages.
