Abstract: In this paper we propose an alternative way to study robustness and vulnerability of complex networks, applying a modal analysis. The modal weights of the network nodes are considered as a measure of their busyness, which is further used for preferential removal of nodes and attack simulation. Analyses of the attack vulnerability are carried out for several generic graphs, generated according to ER and BA algorithms, as well as for some examples of manmade networks. The results are compared to those obtained by deletion of nodes according to some standard measures and it was found that a modal weight based attack causes significant disintegration of manmade networks by removing a small fraction of the busiest nodes.
