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

Figure 3

The process of cascading failure. (a) The left and right sides represent a computational-resource network and a physical-resource network, and the nodes are connected randomly. The shadow nodes indicate the deliberately damaged nodes of network . (b) The damaged nodes are disconnected from network and network . Those belonging to the largest connected cluster in will be preserved. Consequently, the node will be deleted. (c) Because of the node’s failure in the network , the node in the network has no interlinks. also fails. (d) It demonstrates that the node does not belong to the giant network and fails. (e) The nodes’ failure occurs in the network , and the interlink is disconnected from . Thus, fails. (f) The nodes of both networks do not fail anymore and reach a stable state.
