A New Routing Strategy to Improve Traffic Congestion for Scale-Free Network

In order to increase the critical value of phase transition, which can be used to measure the traffic condition, in this paper, a new routing strategy to improve traffic congestion on scale-free network is proposed. Instead of using the routing strategy of shortest path, a new routing strategy is given to find a routing path with the shortest time delay. Simulations results indicate that the new routing strategy can better improve the traffic congestion compared to the shortest path routing strategy.
