Abstract
The effect of link and node capacity on traffic dynamics are investigated in weighted scale-free networks by adopting a traffic routing model with local node strength information: . The link bandwidth is controlled by: = max ( ,1), and the capacity of nodes is controlled by: max ( , 1). The phase transition from free flow to congestion is reproduced. The optimal routing strategy is sought out. When increases from zero, the optimal strategy changes from preferring low-strength nodes to high-strength nodes. When ≈ 1.0, there will be two optimal routing strategies. When is low, the system’s behavior is controlled by link bandwidth, while it is controlled by node capacity when is high. Our work may be useful for the design of modern traffic systems and communication networks.
