Instability of scale-free networks under node-breaking avalanches

Abstract: The instability introduced in a large scale-free network by the triggering of node-breaking avalanches is analyzed using the fiber-bundle model as conceptual framework. We found, by measuring the size of the giant component, the avalanche size distribution and other quantities, the existence of an abrupt transition. This test of strength for complex networks like Internet is more stringent than others recently considered like the random removal of nodes, analyzed within the framework of percolation theory.

“…We didn't discuss the distribution of the number of the shortest paths passing through a vertex, which has a power-law form in scale-free networks [235,236], and many other interesting problems (see, e.g., Refs. [237][238][239][240][241][242][243][244][245][246][247][248][249][250][251]). After this review had been submitted, we learned about the review of Albert and Barabási on the statistical mechanics of networks under preparation [252].…”

“…The procedure enables us to study overload breakdown triggered by the redistribution (and increase) of load in a growing network. This is in contrast to earlier models of cascading breakdown phenomena, all dealing with vertex breakdown, that has taken a fixed network as their starting point [12,13]. * Electronic address: holme@tp.umu.se…”

“…An important question for many real-world situations is how attacks affect the functions of a network when the flow of information or other physical quantity in the network are taken into consideration. In particular, the removal of nodes changes the balance of flows and may trigger a cascading failure [31][32][33][34], as the one that happened on August 10, 1996 in the western U.S. power grid [35,36]. A simple model has been recently introduced [14] for cascades of overload failures in complex networks.…”
