Qianguo Chen: the Dynamics Behavior and Immune Control Strategies of Sirs

In reality networks may have random property, small-world property and scale-free property, so in this paper we introduce the heterogeneous network model. We construct the heterogeneous network based on ER random network, WS small-world network and BA scale-free network. Then we use the random rules to interconnect the three sub networks that generate the heterogeneous network. By analyzing the characteristic network data, we can draw the corresponding degree distribution graph. We study the spreading behavior of the infectious SIRS model with immunization based on the heterogeneous network and two different artificial immunization strategies. Then we perform simulation experiments by using the A(H1N1) type influenza virus in the heterogeneous network. The result shows that artificial immunization can greatly reduce the number of infections even though the network has only a single property, and can obtain more pronounced effect, so as to effectively control the disease spreading on heterogeneous networks.
