A Proposal of P2P Content Retrieval System Using Access-Based Grouping Technique

摘要

In recent years, the diversification and ubiquitousness of information is rapidly advancing due to the development of the information and communication technology. As for the usage of the information, the attention of sharing of information using P2P network rises, and it is becoming to be used in many fields. The distributed hash table (DHT) is one of the typical overlay networks on P2P. However, there is a problem of lacking of flexibility in the retrieval on DHT. In this paper, to improve the convenience of the content access, we propose an efficient content access method based on the grouping technique of the contents using the content access history and frequency and the evaluation of grouping efficiency (precision, recall) is performed by the simple simulation.
