The Target Recovery Strategy for Preventing Avalanche Breakdown on Interdependent Community Networks

Figure 1

The schematic diagram of interdependent community networks. The ICNs are constructed by coupling two networks with the same community structures and the same average degree. Each node belongs to exactly one community and has two types of connectivity links: intracommunity links (black solid lines) and intercommunity links (yellow solid lines). The dependency links (red-dotted lines) are restricted to only connecting nodes within the same community among networks. For example, a node in the community m₁ of subnetwork A only depends on a node in the same community m₁ of subnetwork B. Furthermore, the dependency relation between networks implies the influence of failure for a pair of interdependent nodes: if one fails, the other fails too.
