Abstract: | In this paper, we study the information traffic flow in communication networks with scale-free topology. We consider the situation arising when packets are delivered to non-homogeneously selected destinations. It is found that the network capacity Rc increases with the increase of 〈k〉 (average degree of destination nodes) under local routing strategy. In contrast, Rc is essentially independent of 〈k〉 under shortest path strategy. Based on this finding, an integrated routing strategy that can enhance network capacity is proposed by combining the two strategies. |
