Susceptible-Infected-Susceptible Virus Spread Model in 2-Dimension Regular Network under Local Area Control

A local area control SIS model based on 2 dimension regular network is proposed. The process of virus spreading is studied in 2 dimension regular network under local area control. The research suggests that with the span of local area control increases, the stable infected proportion to reduce. The theoretical analysis and analog simulation shows that there is a critical value in the model. Only when the product of spreading efficiency beyond the critical value, can the virus spread in the network continuously and stably.
