Delay Effect on a Malware Propagation Model Incorporating User Awareness

As the communication networks become more and more popular, there is a growing surge in the amount of malware which utilize communication networks as its propagation mechanism. For this reason, a delayed SID (susceptible nodes-infected nodes-nodes with user awareness) malware propagation model incorporating user awareness is proposed to explore propagation law of malware in this paper. Exhibition of Hopf bifurcation is analyzed by taking the time delay as bifurcation parameter. Furthermore, properties of Hopf bifurcation are explored using center manifold method. Finally, numerical simulations are carried out to verify the obtained results.
