基于异质移动网络的破坏性病毒传播模型

针对现有研究没有考虑移动网络节点异质性与没有构建破坏性病毒传播模型的问题，提出一个基于异质移动网络的破坏性病毒传播模型。通过考虑移动网络节点的异质性，进一步将易感染状态划分为新系统状态和旧系统状态，并结合破坏性病毒的潜伏与爆发特性将感染状态划分为潜伏状态和爆发状态。计算了模型的平衡点与传播阈值，并指出当传播阈值大于1时，模型在正平衡点处不稳定；当传播阈值小于1时，模型在正平衡点处局部渐近稳定。在NW小世界网络和BA无标度网络上进行仿真对比实验，仿真结果表明，两个网络的病毒传播速度不同，NW网络存在病毒完全消除的情况，而BA网络中的病毒不会被完全清除。

Destructive virus propagation model based on heterogeneous mobile networks

Aiming at the problem that the existing research does not consider the heterogeneity of mobile network nodes and the failure to construct a destructive virus propagation model, this paper proposed a destructive virus propagation model based on heterogeneous mobile networks. By considering the heterogeneity of mobile network nodes, it further divided the uninfected state into a new system state and an old system state, and combining with the latent and explosive characteristics of the destructive virus, it divided the infection state into a latent state and an explosive state. It calculated the equilibrium point and propagation threshold of the model, and pointed out that when the propagation threshold was greater than 1, the model was unstable at the positive equilibrium point; when the propagation threshold was less than 1, the model was locally asymptotically stable at the positive equilibrium point. It carried out the simulation experiments on the NW small world network and the BA scale-free network. The simulation results show that the virus propagation speeds of the two networks are different, and the NW network has a complete elimination of the virus, but BA does not have this situation.
