The network robustness against cascades is crucial for many networked systems. In the paper, we enhance the network robustness against cascades by rewiring edges of networks. Three edge-rewiring strategies are compared, including random rewiring strategy (RRS), assortative rewiring strategy (ARS), and low-polarization rewiring strategy (LPRS). The results show that ARS is more effective than RRS to...
Models of conflict in networks provide insights into applications ranging from epidemiology to guerilla warfare. Barabási, Albert, and Jeong modeled selective attacks on networks in which an attacker targets high-order nodes to destroy connectivity; Nagaraja and Anderson extended this to iterated attacks where the attacker and defender take turns removing and rebuilding nodes and edges according to...
Due to the steady evolution and increase in sophistication of peer to peer botnets, it is necessary to understand the structural potential in this type of intruder tool. We formally model the P2P botnets with the help of complex systems. We propose metrics to measure the structural potential of different types of P2P botnets. We also propose a simulative framework to investigate the robustness of...
