Impact of traffic demands on load distribution in congested scale-free networks

Traffic demand is one of the most important factors to affect the traffic flow pattern or load distribution in congested networks. In this paper, we investigate the load distributions and relations between the load and degree of the node for different traffic demands in scale-free networks. Different kinds of load distributions are obtained under different traffic demands. Furthermore, the impact of link capacity on load distribution in congested scale-free networks is also discussed.
