To improve robustness for the complex network, this paper propose a novel probabilistic approach to allocate redundancy links based on nodal degree, i.e. preferential allocation, inverse preferential allocation, and Hiding Redundancy Links (HRL) strategy. The authors find that allocating redundancy links can efficiently improve robustness of networks to tolerate the coordinated attack. Especially, I-I case, which both source node and destination node are chosen by inverse preferential allocation, performs the best. Furthermore, they investigate the effects of HRL strategy under the coordinated attack, and the simulation shows that HRL strategy can achieve the better performance than never.
