Comparative analysis of transport communication networks and q-type   statistics
  We have obtained the Tsallis distribution from the maximum entropy approach using constraints on the first and the second moment, together with the normalization condition. We have constructed railway and highway communication networks for the Moscow region and the airline network for the Russian Federation. The fitting shows that the degree distributions for these networks are described with the q-exponential function. In case of the railway and highway networks, the nodes degrees distributions are well fitted with the skewed normal distribution, while in case of the airline networks we have used the power law distribution for fitting. The studies of the epidemics spreading processes in these networks show that the epidemics threshold decreases with a decrease of the constraint on the degree.
