SIS Contagion Avoidance on a Network Growing by Preferential Attachment

Abstract

The economic and convenience benefits of interconnectivity drive the current explosive growth in networked systems. However, as recent catastrophic contagious failures in numerous large-scale networked infrastructures have demonstrated, interconnectivity is also inherently associated with various risks, including the risk of undesirable contagions. This paper reports on a work-in- progress on network formation subject to Susceptible-Infected-Susceptible (SIS) contagion risk mitigation. As opposed to existing research, we concentrate on network growth. Using a generalized form of preferential attachment, we consider evolving networks where each incoming node to the network combines a preference for connecting to high degree nodes with an aversion for contagion risk. Our initial simulation results indicate that contagion risk aversion significantly alters the topology and contagion propagation for an emerging network. We also discuss the computational aspects of our simulation and our future plans to extend this model.
