摘要：In this paper, through analyzing the process of publishing resource files in DHT network and from the viewpoint of making full use of the information stored in values nodes, we propose two methods to improve the lookup efficiency of source nodes: values-node-based lookup algorithm and source nodes exchange algorithm. The former firstly sends find_node message to those found values nodes, then sends get_peers message to nodes in the returned nodes-list so that increase the number of source nodes in fewer iterations. The latter organizes source nodes into a connected graph taking advantage of the information stored in values nodes, and based on this, with additional interactive messages we can improve the performance of looking up source nodes.
