Math 164 Final Report: Virus-Spreading in Scale-Free Networks
نویسنده
چکیده
Computer viruses are increasing in number and severity, and current tactics for preventing their spread frequently fail. To understand the computer virus phenomenon, I used a model of the internet called scale-free networks. I collected data from three different types of epidemic simulation. The results suggest that a concentrated effort to use anti-virus techniques at the busiest e-mail servers with frequent updates would significantly reduce the spread of e-mail viruses.

The Internet, as well as many other networks, has a very complex connectivity recently modeled by the class of scale-free networks. This feature, which appears to be very efficient for a communications network, favors at the same time the spreading of computer viruses. We analyze real data from computer virus infections and find the average lifetime and prevalence of viral strains on the Intern...

متن کاملTheory of Rumour Spreading in Complex Social Networks
We introduce a general stochastic model for the spread of rumours, and derive mean-field equations that describe the dynamics of the model on complex social networks (in particular, those mediated by the Internet). We use analytical and numerical solutions of these equations to examine the threshold behaviour and dynamics of the model on several models of such networks: random graphs, uncorrela...
متن کاملEpidemic dynamics and endemic states in complex networks.
We study by analytical methods and large scale simulations a dynamical model for the spreading of epidemics in complex networks. In networks with exponentially bounded connectivity we recover the usual epidemic behavior with a threshold defining a critical point below that the infection prevalence is null. On the contrary, on a wide range of scale-free networks we observe the absence of an epid...
متن کاملHalting viruses in scale-free networks.
The vanishing epidemic threshold for viruses spreading on scale-free networks indicate that traditional methods, aiming to decrease a virus' spreading rate cannot succeed in eradicating an epidemic. We demonstrate that policies that discriminate between the nodes, curing mostly the highly connected nodes, can restore a finite epidemic threshold and potentially eradicate a virus. We find that th...
