Probability routing strategy for scale-free networks

► Probability routing strategy is proposed for improving network traffic capability. ► Its network capability can be 30 times of that of the shortest path. ► Its average routing path length is only 10% longer than that of the shortest path. ► Its network capability can be over 50% higher than that of the efficient path. ► Its average routing path length is over 10% shorter than that of the efficient path.
