Abstract
P2P (Peer-to-Peer) file sharing, which is one of the most popular applications, has recently gained significant attention in both academic and industrial areas. However, in most P2P systems, the overlay network is built independent of the physical network. The topology mismatch problem greatly limits the system performance.
In this paper, we proposed a hierarchical proximity join(HPJ) mechanism based on Gnutella P2P system and aiming at alleviating the mismatch problem. The mechanism is adopted when peers joining and makes the overlay network be more close to the physical topology. A new peer gets proximity information from some active peers in the network. Our studies tells that HPJ alleviates the mismatch problem and shortens search response time.
