Unfairness in the e-Mule File Sharing System

Measurement studies have shown that the probabilities of file possession and the arrival rates of file requests have an important impact on the file downloading times in p2p file sharing systems resulting in unfair performances. A model has been proposed to capture this phenomenon. This model is used to derive the qualitative impact of system parameters on performances. However to obtain results for realistic p2p networks one is confronted with the large number of files in these systems. To show the influence of the number of files shared in the system we present results obtained by simulations in the case of small to medium size systems.
