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。
With the help of simulation experiments, the rules of P2P file distribution and document pollution are revealed, and corresponding countermeasures are put forward according to common pollution means. Experiments show that the proposed “remind-delete” cooperation mechanism can effectively increase the difficulty of pollution and reduce the success rate of pollution, thus alleviating the severe file pollution problem in P2P network to a certain extent.
