Minimizing File Downloading Time In Stochastic Peer To Peer Networks

ABSTRACT The peer-to-peer (P2P) file sharing applications are becoming increasingly popular and account for more than 70% of the interneta, cs bandwidth usage. Measurement studies show that a typical download of a file can take from minutes up to several hours depending on the level of network congestion or the service capacity fluctuation. In this paper, we consider two major factors that have significant impact on average download time, namely, the spatial heterogeneity of service capacities in different source peers and the temporal fluctuation in service capacity of a single source peer.
