摘要
P2P社区是具有相似兴趣节点的集合,相似兴趣节点聚簇有助于提高资源共享和发现的效率。针对P2P网络中节点特性的差异,社区不一定都能够提供高资源共享率的问题,提出一种基于信任的自组织社区形成模型,从节点间信任的建立、信任值的存储、信任值的计算三个方面具体研究。随着节点间信息共享的频繁程度变化和节点间信任值的动态更新,P2P网络中能够呈现不同的社区结构。
P2P community is a set of nodes with similar interest, which can help to improve the efficiency of resource sharing and found. According to the characteristics of the different nodes in P2P network, community can not provide high resource sharing rate, a self - organized P2P community model is put forward based on trust. The main contribution of this paper is the trust establishment, trust value storage and trust value calculation. With the trust value changing and upda- ting, P2P network can show different community structures.
