SIRS virus spreading model and computer simulation in regular network under local area control
规则网络中的SIRS病毒局域控制建模与仿真*

This paper proposed a local area control SIRS virus spreading model based on 2-dimension regular network. Theoretical analysis and computer simulation show that the local area control strategy is efficient to control virus spreading. The study finds that system state will reach a steady state with time; the stable infected proportion is related with spreading efficiency, controlled individual proportion and the probability of individuals lose its immunity. Only when spreading efficiency beyond a critical value, can the virus spread in the network continuously and stably.
