摘要:
分析P2P网络文件污染的产生和传播机制,建立基于Markov生灭过程的污染传播模型,推导出产生率、污染水平和网络负载公式,得出信誉系统对污染水平与网络负载有抑制作用.仿真实验表明,模型对污染机制具有较强的描述能力; 污染水平与网络负载具有较强的相关性; 用户对污染文件的识别能力在污染传播过程中起决定作用,判别能力越强越能够限制污染传播; 共享率和信誉系统利用水平对控制污染的效果不明显.该研究为有效控制P2P网络污染的研究工作奠定了基础.
Abstract:
By analyzing the pollution origination and propagation in peer-to-peer(P2P)network, a pollution propagation model is established based on the Markov birth-death process. The expressions of birth rate, pollution level and network workload are deduced, and the conclusion is drawn that the reputation system is effective in controlling pollution level and network workload. Simulation shows that the proposed model is an effective approach for modeling pollution. Pollution level is correlative with network workload. Pollution level is strongly determined by the ability of identifying polluted files. Sharable rate and popularization rate of the reputation system are less effective in controlling pollution level. This work paves for the research of pollution-controlling of P2P network.
