移动P2P网络中的病毒传播建模

摘要

The mathematical model of virus propagation in the mobile peer-to-peer(MP2P) networks is proposed by applying Epidemiology. Based on the proposed model and using the special digital-analysis software Matlab, large-scale experiments are done so as to examine the effect of the MP2P-related parameters on virus propagation. The results of these experiments illustrate that different parameters have different effects on virus propagation, among which the average downloading rate and the average recovery rate of fixed peers have the strongest effects on virus propagation.%对移动P2P网络的体系结构和关键协议进行了深入研究分析；在此基础上,根据病毒传播特点并利用流行病学理论,提出了移动P2P网络中病毒的传播数学模型.基于提出的病毒传播模型,使用专门的数字分析软件进行了大量仿真实验,实验主要考查了各P2P参数对病毒传播的影响.实验分析表明,通过控制固定节点的下载率和恢复率这两个影响病毒传播最关键的参数能有效遏制移动P2P病毒传播.
