We study the betweenness centrality of fractal and non-fractal scale-free network models as well as real networks. We … compared to non-fractal models. We also show that nodes of both fractal and non-fractal scale-free networks have power law … betweenness centrality distribution P(C) ~ C^δ. We find that for non-fractal scale-free networks δ = -2, and for fractal scale …
