Dynamics and Control of Worm Epidemic Based on Mobile Networks by SEIQR-Type Model with Saturated Incidence Rate

摘要: The mobile networks have increasingly facilitated our daily life but are also breeding grounds for malicious worms, which considered as the main threat to cyber security. purpose of this paper is analyze dynamics worm propagation and control epidemic based on mobile-phone networks. Accordingly, we establish an SEIQR-type model explore with saturated incidence rate. This shows that if basic reproduction number less than 1, worm-free equilibrium asymptotically stable, will eventually disappear remain under control; in addition, greater asymptotical stability worm-existence derived imply persistent uncontrollable. Our results give new insights network security, namely, predicting spreading tendency, identifying strategies, estimating popularity level. Numerical experiments conducted show rationality obtained effectiveness strategies.
