Research on the Pollution Prevention Mechanism of P2P

The file pollution is the universal existence question in P2P file sharing system nowadays,and user's behavior is the important factor which causes the pollution.In this paper,based on studying user's behavior,we established a pollution file propagation model,which described user behavior's impact on pollution propagation such as awareness of pollution,trend of sharing,and then we proposed the corresponding anti-pollution mechanisms.Simulation results showed that this mechanism can thwart diffusion of pollution in the network effectively.6figs.,12refs.
