Strategic Defense and Attack of Complex Networks
This article shows how policy choices about defense and attack investments at the component level can be made for arbitrarily complex networks and systems. Components can be in series, parallel, interdependent, interlinked, independent, or combinations of these. Investments and utilities are determined for the defender and attacker dependent on their unit costs of investment and contest intensi...
متن کاملCascade-based attacks on complex networks.
We live in a modern world supported by large, complex networks. Examples range from financial markets to communication and transportation systems. In many realistic situations the flow of physical quantities in the network, as characterized by the loads on nodes, is important. We show that for such networks where loads can redistribute among the nodes, intentional attacks can lead to a cascade ...
متن کاملSequential Defense Against Random and Intentional Attacks in Complex Networks
Network robustness against attacks is one of the most fundamental researches in network science as it is closely associated with the reliability and functionality of various networking paradigms. However, despite the study on intrinsic topological vulnerabilities to node removals, little is known on the network robustness when network defense mechanisms are implemented, especially for networked...
متن کاملDegree-based attacks and defense strategies in complex networks.
We study the stability of random scale-free networks to degree-dependent attacks. We present analytical and numerical results to compute the critical fraction p_{c} of nodes that need to be removed for destroying the network under this attack for different attack parameters. We study the effect of different defense strategies, based on the addition of a constant number of links on network robus...
متن کاملA microRNA cascade in plant defense.
MicroRNAs (miRNAs) and other small interfering RNAs (siRNAs) play an important regulatory role in the growth and development of eukaryotes. miRNAs in plants are known to regulate the expressionof a number of key developmental and stress-related genes. New insight into miRNA function was gained recently with the discovery that several miRNA families target genes encoding nucleotide binding site–...
