Abstract

In addition to searching, browsing is yet another requirement of P2P file sharing systems. Nevertheless, none of the recent P2P DHTs can closely connect peers with the same interests together so that it is not practical to provide browsing service in such systems. In this paper, we define a new cayley graph to support logical grouping, and based on this cayley graph, a set of P2P DHT protocols which is suitable for providing file browsing service is also designed. Performance evaluation indicates that the new protocols can reach the theoretical lower bound of routing table size and query path length. Furthermore, the robustness of ComNET is also better than most of the P2P DHTs recently proposed.
