摘要
借助仿真实验揭示了P2P文件分发与文件污染的规律,针对常用的污染手段提出了相应的对策。实验证明,文中提出的"提醒-删除"合作机制可以有效地增加污染的难度,降低污染的成功率,从而在一定程度上缓解了P2P网络中严峻的文件污染问题。
This paper analyses the problem of file pollution on P2P file sharing networks,presents various kinds of pollution techniques,and puts forward possible counter-measures to them.In particular,a novel cooperative ＂warning-delete＂ approach is proposed to alleviate the most serious version pollution.The effectiveness of this approach is proved by simulation experiments.
