Abstract:

Inspired by the feature that most of the real world networks are made of interwoven overlapping 

communities, a new multi-targets attack strategy is proposed. It helps reveal the influence of community 

structure to the robustness of complex networks. By attacking the nodes with higher community member-ship, the new strategy can drastically alter the internal structures and the overlapping relations of several

communities, that will result in performance deterioration of the whole network. Simulations based on Kl-

emmEguíluz(KE) network and Internet AS network demonstrate the prominent performance of the new 

strategy and reveal the unique behavior that the number of communities decreased rapidly under the new 

attack strategy. Moreover, the comparison with the random attack strategy and the degree based attack 

strategy indicate the highdestructive ability of the new technique to the structure and the performance of

 the complex networks.

Key words: complex networks, robustness, overlapping community, multitarget attack strategy
