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. We 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, we investigate the effects of HRL strategy under the
coordinated attack, and the simulation shows that HRL strategy can achieve the better performance than never. More
interestingly, the relationship between threshold of crash and the number of redundancy links appears to achieve
nonlinear by the HRL strategy. Therefore, a small fraction of redundancy links is highly contributed to improve the
tolerance attack dramatically. This paper provides an insight on improving network robustness to tolerant the coordinated
attack by allocating redundancy links.
