摘要：
Cooperation between participants is essential to P2P applications' viability. Due to obscure possibility to match peers' needs and supplies in pairs, the widely used pair-wise exchange-based incentive schemes perform poorly. The N-way exchange-based incentive scheme enlarges the matching possibility by introducing n person exchanges. But some old problems remain and some new ones emerge with the N-way design. In this paper we present an enhanced n-way exchange-based incentive scheme for P2P file sharing systems. By distributing extra tasks to all the peers involved in an n-way exchange, the proposed scheme eliminates prohibitive computation and communication cost on the cooperators, resulting in greater efficiency, effectiveness, and security.
