摘要 为了提高P2P网络资源搜索效率,研究并分析了一种新的P2P系统资源发现机制——基于历史记录的智能搜索机制(The Intelligent Search Based on History,ISBH).该机制的特点是在转发请求信息时对邻居节点进行选择,而不是盲目或者随机转发.通过实验室模拟环境对ISBH与另外几种搜索算法做了性能比较,仿真结果表明IS-BH能够在使用较少消息数量的情况下,获得比较高的搜索成功率,显著提高了P2P系统的资源搜索效率. Improving efficiency of resources search in P2P systems, a new P2P system resources discovery mechanism-the Intelligent Search Based on History（ISBH）, is studied and analysed. This method selects the number of neighbors, rather than randomly or blindly forward transmitting open-eared information. Through laboratory simulation environment, the performance is compared between ISBH and several other search algorithms. The results show that ISBH which achieves in higher search success rate by using less information significantly enhances the P2P system resources search efficiency. The study for improving the efficiency of P2P information retrieval has some useful lessons.
