Susceptible-Infected-Susceptible Virus Spreading Model in Two Dimension Sparse Lattice under Local Area Control

摘要

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