Epidemic Processes over Time-Varying Networks

The spread of viruses in biological networks, computer networks, and human contact networks can have devastating effects; developing and analyzing mathematical models of these systems can be insightful and lead to societal benefits. Prior research has focused mainly on network models with static graph structures, however the systems being modeled typically have dynamic graph structures. Therefore to better understand and analyze virus spread, further study is required. In this paper, we consider virus spread models over networks with dynamic graph structures, and investigate the behavior of diseases in these systems. A stability analysis of epidemic processes over time-varying networks is performed, examining conditions for the disease free equilibrium, in both the deterministic and stochastic cases. We present simulation results, propose a number of corollaries based on these simulations, and discuss quarantine control via simulation.
