Interdependency and Vulnerability of Multipartite Networks under Target Node Attacks

Figure 3

Network model for depicting the cascading failures of a multilayer network subject to node attacks. Networks , , and are with one-to-one correlations. (a) Node 2 of network is originally attacked. (b) The failure of node 2 leads to the failures of nodes 6 and 10 due to interdependency. (c) The model posits that, for each network, only nodes in the LCC will be considered as functional, and therefore, nodes 1, 5, and 9 are removed. (d) As a consequence, the failure of node 2 eventually leads to the existence of only three nodes (4, 8, and 12 or 3, 7, and 11).
