| 英文摘要 | In a heterogeneous peer-to-peer network, different peers may provide different qualities of service, so it is very important and helpful to identify those peers that can provide better services than others. A trust model is thus needed to provide a way for building trust through social control without trusted third parties. In this paper, we propose a new community-based trust model for P2P networks. There are three main features of this model. First, referral trust information is given to communities for each requestor, and in this sense, the prior knowledge of requestors about the environment is used to promote the collaboration. Second, the method to update referral trust value of each community is given, and thus, peers can learn from experiences about the environment. Third, the time aging factors of the both direct experience and indirect experience are taken into account. In order to justify the proposed model, we compare it with the existing models. The experiment results show that the use of community structure indeed improves the performance of the P2P networks. |
