摘　　要：Freenet是一种非结构化对等网络中共享Internet计算机资源的应用,具有灵活可靠的特点。但是网络初始路由效率低,路由跳数非常大。通过减少初始路由中使用广播扩散方式进行资源定位,建立兴趣子网。基于兴趣子网,资源查找时,交换兴趣子网内的信息,提高了资源检索效率,改进Freenet网络中数据查询与获取机制,提高Freenet网络资源出师路由定位的效率。对兴趣子网的Freenet网络中资源定位机制进行性能评估,做了仿真实验。初步的仿真实验证明了兴趣子网划分算法的有效性。Freenet is an unstructured peer-to-peer network of computer resources sharing.It is flexible and reliable.But the initial route network efficiency is low,hops are large.Through reducing the use of broadcast routing of the intial route,and the establishment of the interest-subnet.Using interest-subnet,exchanging information in interest-subnet to improve the efficiency of resource retrieval,improve the network resources subnet Freenet positioning system and improve the efficiency of the network resources.Simulation experiments show the effectiveness of the algorithm of interest division subnet.
