An efficient link closing strategy for improving traffic capacity on scale-free networks

Network structure and its traffic capacity are closely related. A reasonable layout of the network structure can bring a larger traffic capacity. In this paper, a high-contraction -centrality-first (HCCF) strategy is proposed to optimize the network structure reasonably. The traffic performance with the HCCF strategy under the shortest path routing is investigated on the scale-free networks. The obtained simulation results show that the HCCF strategy not only has certain advantages in improving the traffic capacity but also has a lower average path length.
