Immunization of complex networks.
Complex networks such as the sexual partnership web or the Internet often show a high degree of redundancy and heterogeneity in their connectivity properties. This peculiar connectivity provides an ideal environment for the spreading of infective agents. Here we show that the random uniform immunization of individuals does not lead to the eradication of infections in all complex networks. Namel...
متن کاملReactive immunization on complex networks
Epidemic spreading on complex networks depends on the topological structure as well as on the dynamical properties of the infection itself. On general grounds, highly connected individuals and sites exposed to the infection have similar roles in the epidemic propagation. Motivated by this feature, we propose a novel vaccination scheme that exploits information from the details of the infection ...
متن کاملImmunization of Real Complex Communication Networks
Most communication networks are complex. In this paper, we address one of the fundamental problems we are facing nowadays, namely, how we can efficiently protect these networks. To this end, we study an immunization strategy and found that it works almost as good as targeted immunization, but using only local information about the network topology. Our findings are supported with numerical simu...
متن کاملImmunization and epidemic dynamics in complex networks
We study the behavior of epidemic spreading in networks, and, in particular, scale free networks. We use the Susceptible–Infected–Removed (SIR) epidemiological model. We give simulation results for the dynamics of epidemic spreading. By mapping the model into a static bond-percolation model we derive analytical results for the total number of infected individuals. We study this model with vario...
متن کاملGlobal efficiency of local immunization on complex networks
Epidemics occur in all shapes and forms: infections propagating in our sparse sexual networks, rumours and diseases spreading through our much denser social interactions, or viruses circulating on the Internet. With the advent of large databases and efficient analysis algorithms, these processes can be better predicted and controlled. In this study, we use different characteristics of network o...
