一种应用于含权无标度网络的全局路由算法

A global routing method for weighted scale-free networks

针对含权无标度网络提出了一种全局路由算法.该算法利用网络路径上的节点强度信息构建了一种全局路由代价函数,选择使该代价函数最小的路径来传输信息包,有效避开了网络中易发生拥塞的核心节点.实验结果表明,与最短路径算法相比,该算法以较小的平均路径长度的增加为代价,将网络容量提高了十多倍.

In this article,a global routing method is proposed for weighted scale-free networks. To bypass the central nodes and alleviate the congestion,it chooses the best route according to the minimum value of the cost function which is based on the node strength. Simulation results show that the network capacity is improved more than 10 times by our method than by the shortest path strategy at the cost of a slightly growth in the average path-length.
