Dynamical repair strategy of data network controllability processes against DoS attack on complex temporal networks

The controllability of complex temporal networks is one of the most important challenges of the last decade in this type of network. The main goal of controllability methods is to transport a temporal network from an initial state to the final state in a specified time with the minimum number of control nodes. Temporal complex networks have always been under various attacks, especially DoS attacks. Attacks cause the network to lose its full controllability. In this paper, the destructive effects of DoS attacks on controllability robustness have been analyzed and investigated. Then, an optimal method to repair controllability of network processes in the face of DoS attacks is proposed, which returns the network to fully controllable mode by adding the minimum number of new edges. The results demonstrate that the proposed method has increased the controllability of network robustness. Also, the proposed method has worked at a higher speed and with a lower cost (the number of new edges) than other conventional repair the controllability methods.
