Maximum-Bandwidth Node-Disjoint Paths

Mostafa H. Dahshan

摘要:

本文提出了一种求通信网络中具有最大组合带宽的节点不相交路径的新方法。该问题是一个NP完全问题,可以使用整数线性规划(ILP)在指数时间内最优求解。该方法采用Dijkstra算法的最大代价变体和虚拟节点表示来获得最大带宽的节点不相交路径,通过几个仿真,我们比较了我们的方法的性能,现代启发式技术和ILP解决方案。我们表明,在一个多项式的执行时间,我们提出的方法产生的结果是几乎相同的ILP在一个显着降低执行时间。

英文摘要:

This paper presents a new method for finding the node-disjoint paths with maximum combined bandwidth in communication networks. This problem is an NP-complete problem which can be optimally solved in exponential time using integer linear programming (ILP). The presented method uses a maximum-cost variant of Dijkstra algorithm and a virtual-node representation to obtain the maximum-bandwidth node-disjoint path. Through several simulations, we compare the performance of our method to a modern heuristic technique and to the ILP solution. We show that, in a polynomial execution time, our proposed method produces results that are almost identical to ILP in a significantly lower execution time.
