针对在非结构化对等网络(Unstructured Peer to Peer)中查找资源时传统资源搜索方法的检索效率不高、通信开销过大的问题，提出了一种新的基于访问兴趣相似性 P2P网络模型。在对网络结构不作全面改变的情况下，通过发现访问频谱相似节点，建立少量访问频谱相似节点间的远程连接，可以改善传统的非结构化对等网络资源搜索，并在此基础上设计了一种资源搜索算法。仿真试验证明，该模型在一定程度上提高了非结构化 P2P资源搜索的效率，同时减少了网络中的通信冗余信息量。

The low efficiency of resources searching and communication overhead are the main problems of unstructured P2P network. To resolve these problems,a new P2P network model based on interest similarity is given in this paper. The access spectrum similar nodes are found in peer to peer networks. Establishing the few remote connections among these nodes will improve the traditional unstructured P2P network resources searching, and on this basis,a new resources searching algorithm is designed. The simulation shows that the model can improve the resources searching efficiency of unstructured P2P network,while reducing the information redundancy in the net.
