In many real networks, the information or energy flow often communicates through the shortest paths between pairs of nodes, whereby the betweenness centrality may play an important role in the robustness problems against cascading failures. In this paper, a betweenness-based node weighting strategy is proposed to explore the robustness of weighted heterogeneous networks against cascades of overload failures. The optimal weighting parameter obtained by the betweenness-based strategy is almost the same as that of the degree-based strategy. Howeve...
