The decentralized structure makes P2P network an effective model for file sharing. However, how to avoid the "freerider" 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 constructs a decentralized trust model. The nodes which provide reliable service have high trust degree. Accordingly, these high degree nodes are much easier to obtain reliable service in the system. The experimental results show that the model can effectively control free-rider and improve efficiency ofthe system.
