Complex network model of user-share behaviors in P2P applications

This paper investigated the architecture of some popular P2P applications in the Internet,and presented a complex network model(SNET) to characterize the user-share behaviors in P2P applications.This model was driven by the increasing amount of sharing files in each user,and evolved into a complicated topology just like the real P2P applications.Also analyzed the simulation results of SNET and the measurement of P2P applications in TUNET.The probability distributions of the number of user connections in both SNET and P2P applications follow a power law.
