| 摘 要： | 本文从节点根据资源的相关性自组织构造网络的角度出发,提出一种基于信息聚类的P2P网络自组织构造方法。节点基于自身了解的知识,自主地建立并维护与其它节点的拓扑连接。通过节点间的信息聚类,资源相似节点聚集在同一主题域,实现节点资源的有序组织。对于给定的查询,它的答案集就在对应的主题域,查询处理范围小,查询处理效率高。实验分析表明,本文提出的基于信息聚类的P2P网络自组织构造方法起到了优化网络性能的效果。

| Abstract: | A method of self-organizing the P2P network based on information clustering is proposed.For the sake of effective resources organization,an overlay network topology named TONET is proposed by combining the strengths of the traditional centralized networks and the distributed networks.The novel overlay network can be generated by dynamically clustering the peers that include the relevant topic document set and by linking them together.And then with the efficient organization of the resources,TONET can restri... |
