The decentralized structure makes P2P network an effective model for file sharing. However, how to avoid the ??free-rider?? of file sharing in P2P network is a crucial problem. With the combination of fairness thought, an incentive strategy based on peer trust degree has been proposed. Each peer in this model is a credit entity. Each node submits feedback about queried node after transaction, and...
