Journal ArticleDOI
Resilience of the internet to random breakdowns
TL;DR: This work shows analytically and numerically that for alpha=3 the transition never takes place, unless the network is finite, and finds that the physical structure of the Internet is impressively robust, with p(c)>0.99.
Journal ArticleDOI
Breakdown of the internet under intentional attack.
TL;DR: It is argued that, near criticality, the average distance between sites in the spanning (largest) cluster scales with its mass, M, as square root of [M], rather than as log (k)M, as expected for random networks away from criticality.
Journal ArticleDOI
Efficient immunization strategies for computer networks and populations.
TL;DR: It is shown that the immunization threshold is dramatically reduced with the suggested strategy, for all studied cases, and analytically the critical threshold for complete immunization is studied.

Complex Networks: Structure, Robustness and Function
Reuven Cohen,Shlomo Havlin +1 more
TL;DR: This chapter discusses random network models, which are based on the Erdos-Renyi models, and their application in the context of complex networks, where distances in scale-free networks are small and distances in complex networks are large.
Journal ArticleDOI
Scale-free networks are ultrasmall.
Reuven Cohen,Shlomo Havlin +1 more
TL;DR: It is shown, using analytical arguments, that scale-free networks with 2
