考虑连边保护的自适应网络病毒传播模型

Network-Adaptive Virus Propagation Model with Link Protection

考虑健康个体以保证自身安全为前提寻找新的邻居时采取保护措施,在确保邻居处于健康状态之后撤销连边保护措施,文中使用平均场方程建立了一种新的自适应网络病毒传播模型。模型能够预测系统的稳态感染水平,并用蒙特卡洛方法分析验证。研究表明,病毒门限只受到部分参数的影响,连边保护机制和边重连机制分别在两个参数区域内承担主要的抗病毒作用。此外,连边保护机制能够极大地增加社团强度。

Individuals can perform protection during looking for new neighbors in terms of self security. They discard protections except that they are assured that their neighbors are healthy. A new network-adaptive virus propagation model is established using the mean field equation. The model can predict the steady infection verified by Monte Carlo simulation. Simulation results demonstrate that the virus threshold partly depends on the parameters, and the link protection and rewiring edges play important roles in resisting disease with different parameter regimes, respectively. In addition, the link protection mechanism can enhance the community function.
