To control congestion in information networks, we performed TCP/IP like traffic simulations using the hub avoidance routing which incorporates the number of adjacent nodes as costs. In these simulations three sample networks were adopted: Scale-Free network(SFN) which has the similar structural properties to those of the Internet, Random Network(RN) as a homogeneous structure network, and Random Geometric Networks(RGN) as a structural model for wireless ad-hoc network. In comparison with the case of the shortest path routing, the hub avoidance routing was found to be more effective on a traffic congestion control, and had higher packet reachability for destination nodes. In the case of RGN, however, this method had not any congestion suppression effect at all because the cause of congestion in RGN is not on hub nodes but on bridge nodes that connect small network islands.
