Study of Virus Propagation Model Under the Cloud
The impacts of the changes about the number of the nodes with different states by the external factors are not considered in the traditional model. So, they are not suitable for the cloud network which is dynamic. A virus propagation model of computer which applies to the cloud environment, HSIR propagation model, is proposed in this paper. It takes the dynamic changes of the cloud environment, the implementation of the immunization strategy and the time difference between the virus spread and the implementation of the immunization strategy into account. In addition, the balance point of the HSIR model is found and the stability of the balance point is proved by the mathematical theory.
