Structural Controllability of Optimized Networks with Onion-Like Topologies
Recently, an optimization method has been proposed to increase the ability of complex networks to resist intentional attacks on hub nodes. The finally optimized networks exhibit a novel type of “onion-like” structure. At the same time, structural controllability of complex networks also has been a hot research topic in recent years. Thus, structural controllability of “onion-like” networks deserves sufficient discussion. In this study, we explored the relationship between the attack robustness and structural controllability of scale-free networks before and after optimization. After implementing large quantity of numerical simulations, it has been found that the optimized scale-free networks have both increased robustness and enhanced structural controllability. Current research results can shed some light on the deep understanding of structural complexity and dynamical properties of real-world networked systems.
