| Abstract(in English) | In peer-to-peer services it is very important to consider robustness against frequent peer failures (e.g., leaving their logical network), since comings and goings of peers are directly affect the stability of their logical network. Replication of a content is one of useful techniques to improve such robustness. However, the effectiveness of replication is heavily dependent on the topology of the logical network. In this paper, we first investigate the effect of the logical network topology (especially the power-law nature) on replication methods. We then consider new query forwarding methods taking the logical network's power-lawproperty into account to improve the performance of P2P service. Our simulation results show that there is a possibility to improve the query performance greatly by considering the nature of power-law in P2P networks. |
