| 摘 要： | 随着Napster,Gnutella等文件共享应用的成功,对等网络(P2P)得到了快速发展,高效的资源搜索成为P2P应用中的首要问题,现已提出了许多搜索方法。主要研究无结构化P2P网络中的资源搜索机制。在分析现有搜索方法特点的基础上,对它们进行分类,然后深入分析各类搜索方法中的关键技术,并从搜索成功率、产生消息量、对网络动态变化的适应性和网络维护的复杂程度等方面进行比较,最后进行总结。

| Abstract: | The success of file-sharing applications such as Napster and Gnutella makes Peer-to-Peer networks developing rapidly.Efficient resource discovery is the first step towards distributed resource sharing.Recently many search methods have been proposed.We gave an overview of search mechanisms for unstructured Peer-to-Peer networks in this paper.Firstly we approximately classified existing search methods based on the features of them.Then we discussed critical techniques used in these approaches in detail and co... |
