| 摘 要： | 如何高效地搜索资源是P2P网络中最为关键的问题。非结构化的对等网络，一般以广播方式作为其搜索的基本策略，引发较大的网络流量，因此，提出改进的搜索策略，包括把节点划分为拥有丰富资源的核心节点和稀疏资源的边缘节点，并为每个节点引入朋友节点，模拟测试表明改进算法稳定有效，降低了网络开销。

| Abstract: | How to search the resources efficiently is the key problem in peer-to-peer networks.Unstructured peer-to-peer networks usually use broadcasting as its basic search strategy and cause a larger network flows.This paper introduces some improved search approaches,including dividing nodes into two types:kernel-nodes with more resources and edge-nodes with less resources,and introducing friend-nodes to each peer.Simulation results show that improved methods enhance the search efficiency and reduce the network costs. |
