Traffic Dynamic in Modularity Structure of Complex Networks

Modularity structure is often found in many different types of complex networks. Especially, this topological property is believed to provide a certain degree of robustness to networks. This belief leads them naturally to investigate the impact of modularity structure on the behavior of networks. In this paper, the authors carry out two simulation studies to monitor traffic dynamic in modularized and non-modularized scale free networks. In the first simulation, coarse-grained traffic is flooded through networks. This paper demonstrates that a modularized structure localizes damages and stops the malicious effect to the whole system.
