摘　　要：提高P2P网络资源快速定位效率是Chord协议的应用之一.提出了一种基于DHT的轻量级Chord资源快速定位算法.该算法根据节点自身资源被访问次数建立资源管理表并利用哈希函数对资源号有序序列实现相同资源搜索时减少遍历次数,也就加快了热度资源查询与定位速度.仿真实验表明,该算法在小型P2P网络中用来提高资源定位效率是可行的.One of the applications of Chord protocol is to improve the fast locating efficiency of P2 P network resources.In this paper,a fast localization algorithm based on DHT for lightweight Chord resources is proposed.A resource management table according to the number of times the node’s resources have been accessed and the hash function to search for the same resource number in order sequence is used.Simulation results show that the proposed algorithm is feasible to improve the efficiency of resource location in small P2 P networks.
