【摘要】 为了改善非结构化对等网络(peer-to-peer,P2P)资源搜索的网络负载大、搜索时间长的缺点。对现有P2P网络资源搜索算法进行了研究,在此基础上,提出一种基于索引表的跳跃式算法,该算法中每一个节点存有一定数量邻居节点的资源索引,节点利用资源索引表以跳跃方式查询节点,网络中的某些节点需要查询资源索引表,而某些节点无需查询资源索引表,直接转发查询消息即可。通过OPNET进行仿真实验表明,该算法能有效的减少网络负载和搜索延时,提高了搜索成功率。更多还原

【Abstract】 To improve the resource searching’s large network loading and long searching time in the unstructured peer-to-peer(P2P) network,a jumping algorithm based on the index tables is presented after researched many algorithms about resource searching in P2P network.In this algorithm each node saved a certain number of nodes’ resource index,the resource index tables is used to search resources by jumping.Some nodes need inquire resource index,but some just put forward the news.The simulation results show that this algorithm can reduce the network loading and searching time effectively,and improve the success rate of resource searching.更多还原
