Abstract:
Abstract—In unstructured P2P networks, replicating most popular files is one of mechanisms, which improve file lookup performances, such as lookup delay and success rate. However, measuring global file popularity is a challenging task because this estimation must consider requests of all peers for this file whereas in unstructured P2P networks like Gnutella, the peer has no global view of the network. Some researches have been done to measure this parameter. Nevertheless, this estimation is still away from reality because the peer, which calculates file popularity, doesn’t consider file popularity estimations of the other peers. In this paper, we try to define a way to calculate a global file popularity based on local estimation of the peer and estimations done by the other peers participating in the network. Our first simulation results reinforce our theoretical formulas and show that our measurement is closer to the real one. More details will be provided and simulation tests will be added in our future contributions.
