Abstract

The study of community networks has attracted considerable attention recently. In this paper, we propose an evolving community network model based on local events, the addition of new nodes intra-community and new links intra- or inter-community. Employing growth and preferential attachment mechanisms, we generate the network with a generalized power-law distribution of nodes’ degrees. Furthermore, we study epidemic spreading in the resulting network by the simple SIS model to understand the influence of the network structure on the dynamics. We find that the existence of communities in networks causes the critical behavior of the spreading dynamics and keeps epidemics endemic.

Keywords: complex networks community networks SIS model
