Abstract:

wireless sensor networks (WSN) have a wide range of applications and are vulnerable to malicious attacks. Focused protection of some nodes from network viruses can improve the overall network destruction resistance and fault tolerance. With the help of Holling-II class predation model, this paper quantitatively studied the dynamic behavior of a class of WSN worm propagation models with focused protection objects and designed targeted virus suppression strategies. Firstly, the local and global asymptotic stability conditions of the model were given. Secondly, the sufficient conditions for the model to generate Hopf bifurcation were investigated, and the direction of the bifurcation as well as the stability of the periodic solution were discussed. Finally, the parameter thresholds for the transformation of the model equilibrium point are derived, and the virus control scheme was designed accordingly. Theoretical analysis and numerical experiments show that the model can provide reference for the prevention and control of network worms.
