摘要：

基于网络级联失效研究，考察相依异构网络ER-BA级联失效动态过程，提出基于节点实时处理能力的负载重分配策略。仿真测试显示，相依异构网络整体鲁棒性受异质化程度较高的网络影响，发生级联失效时应降低网络间的连接强度；以介数为基础的负载重分配策略易引发中心节点失效而降低网络整体鲁棒性，基于实时处理能力的负载重分配策略能有效提高相依网络的整体鲁棒性。

关键词: 级联失效, 相依异构网络, 负载重分配策略

Abstract:

Based on cascading failures of the network, we investigate the same process of interdependent heterogeneous networks such as ER-BA, and propose a load redistribution strategy based on real-time processing ability of nodes. Simulation tests show that the overall robustness of the network is mainly affected by the BA network. The connection strength should be reduced when the cascading process is initiated. The load redistribution strategy based on the betweenness of nodes can easily lead to the failure of the central nodes and reduce the overall robustness of the network. The proposed strategy can optimize the overall robustness of interdependent heterogeneous networks.

Key words:

cascading failure, interdependent heterogeneous networks, load redistribution strategy
