[Retracted] Cascading Failure Dynamics against Intentional Attack for Interdependent Industrial Internet of Things

Figure 5

The fraction of survival nodes in network and . Abscissa represents the proportion of nodes that are not attacked in the targeted-attack process and represents the percentage of the attacked nodes. Ordinate indicates the proportion of remaining nodes when cascading failure stops after the coupled network receives a targeted attack. The red line represents network , the blue line represents network , and the abscissa corresponding to the black line represents the theoretical value of the critical threshold when the networks fail.
