基于Bittorrent网络的快速搜索策略

非结构化P2P网络在大规模网络环境下的资源共享方面具有优越性，针对这些网络的快速资源定位是一个关键问题。Bittorrent是一个简单、高效的P2P文件共享系统，但是该系统只解决了如何高效地下载资源，而没有解决如何高效地搜索资源。该文针对目前BitTorrent网络中资源获取方式存在的不足之处，提出了一种基于BitTorrent P2P网络的快速搜索策略——Incentive Hop Search，并建立模拟程序，对检索的性能与效果做了初步的验证。实验结果表明了该方法的有效性。

Fast Search Method Based on Bittorrent Network

Unstructured P2P networks are more scalable and more effective than centralized networks.How to locate resource rapidly and effectively in unstructured P2P networks becomes a key issue.Bittorrent is a simple,effective P2P file sharing system,but it only solves how to download effectively while how to locate resource is still unsolved.This paper presents a P2P distributed search method(IHS) based on bittorrent P2P network in order to improve its search ability.It implements a simulation program and tests the performance of the system.Experimental results show that IHS is an effective method with high recall rate and low resource usage.
