Abstract |
|
|
| Tree-like hierarchical structure is one of the key features in many real complex systems. To investigate its properties, a
deterministic tree-like hierarchical network model is proposed. Next, the static properties of the tree-like hierarchical networks are
discussed. The simulation and theoretical results prove that the artificial tree-like networks conformably possess small-world and scalefree
properties well. Furthermore, the dynamic cascading failures in the tree-like hierarchical networks are investigated. A weighted
tree-like cascading failure model is proposed, and the impacts of topological structure on the network robustness are investigated by a
set of illustrative simulations. |
