| 摘 要： | 将基于内容的图像检索应用到P2P网络中，提出了一种基于“类簇”的P2P网络信息搜索机制。结合聚类方法和Small world原理，将相似的图像文件聚集到同一个“类簇”中，不同簇之间建立远距离连接；查询时先定位到所属的簇，在簇内广播查询，并根据查询记录更新节点路由表。仿真实验表明该搜索机制具有良好的搜索性能。

| Abstract: | The content-based image retrieval system was introduced into P2P network and a novel search model based on "cluster clustering" was presented. Firstly, according to clustering algorithm and the small-world theory, image files with similar feature were collected together while dissimilar clusters were connected by shortcuts. Furthermore, a query reached its target cluster, and was broadcasted in the cluster. Founded on the previous query result, routing tables were updated. Simulation results show that the model is efficient. |
