摘　　要：文件污染是当前P2P文件共享系统普遍存在的问题,其中用户行为是导致污染的重要因素.在考察用户行为的基础上,建立了一个污染文件传播模型,描述了用户的污染意识、共享倾向等因素对污染传播的影响,并据此提出了相应的反污染机制.仿真实验表明,该机制能够有效地控制P2P文件共享系统中污染文件的传播.图6,表12.The file pollution is the universal existence question in P2P file sharing system nowadays, and user 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.
