A model to study the scaling of traffic fluctuations on complex networks

In a recent article, we studied the dynamics of traffic in complex networks [1]. In particular, we computed how the fluctuations scale with the mean, sigma similar to < f >(alpha). Using a general model which includes nodes with finite capacity we found a continuous range of a values between 1/2 and 1. Here we resume the results, adding a brief analysis about the self-similarity of the traffic dynamics in our model.
