While trying to maximize its own utility subjected to individual <br />rationality, every peer allocates bandwidth resources efficiently according to its debt relationships with <br />competing peers. The more contribution to the system, the better services the creditor will receive from <br />his debtors. In contrast with most of the existing incentives, the whole distributed structure of the <br />system and the practical locating algorithm avoid most of the complexities. Simulations show that the <br />proposed mechanism increase the social utility of the whole P2P system significantly while isolating <br />malicious peers from the network effectively.}, number={2}, publisher={İstanbul Üniversitesi-Cerrahpaşa}
