相互依存网络间的拓扑构建方法
Topological coupling method between interdependent networks
摘要
Abstract
To reduce cascading failures of interdependent networks, it introduces a topological coupling strategy that a network connects another network with same position nodes, by drawing on the experience of inter-similarity coupling, after defining normalized degree, inter-assortativity coefficient and inter-clustering coefficient. Adopting breadth first search algorithm and taking hub node as initial search node, the strategy can improve the matching degree of inter-similarity and extend the application scene. Interdependent ER networks and SR networks are taken as examples and simulated, the result of the experiment implies that the coupling algorithm leads to change from a first to second order percolation transition, and can improve robustness of interdependent networks compared to random coupling algorithm under targeted attacks, random attacks and targeted defenses.关键词
