【摘要】：提出了一种考虑隔离系数和非线性感染率的改进SIRS模型用以描述病毒在网络中的传播过程;通过分析了网络在病毒攻击后的最终状态,并得出了使系统最终稳定的充要条件;当系统满足充要条件时,系统最终稳定于无病平衡点即感染节点消失,当系统不满足充要条件时系统最终稳定于地方病平衡点,最终感染节点数量会稳定在一定比例;除此之外讨论了不同隔离系数对网络安全的影响,最后通过仿真验证分析结论。
[Abstract]:An improved Sirs model considering isolation coefficient and nonlinear infection rate is proposed to describe the transmission process of virus in the network, and the final state of the network after the virus attack is analyzed, and the necessary and sufficient conditions for the system to be stable are obtained. When the system meets the necessary and sufficient conditions, the system will eventually be stable at the disease-free equilibrium point, that is, the infected node will disappear, and when the system does not meet the necessary and sufficient condition, the system will finally be stable at the endemic equilibrium point, and the number of infected nodes will be stabilized in a certain proportion. In addition, the influence of different isolation coefficients on network security is discussed, and the conclusion is verified by simulation.
