Distributed event-triggered control for multi-agent systems under intermittently random denial-of-service attacks

Abstract

This paper considers the event-triggered consensus problem for multi-agent systems (MASs) under intermittently random denial-of-service (IRDoS) attacks. The IRDoS attack compromises communication networks when the attacker is at active periods. Then, the distributed event-triggered controller is designed to achieve the consensus objective, and each agent’s communications towards neighbors are interrupted by the IRDoS attack with a certain probability when the triggered instants are at active periods of attackers. Furthermore, the sufficient conditions on the attack duration and successful probability, under which the designed control protocol guarantees secure consensus of MASs, are proposed. Finally, the effectiveness of the distributed event-triggered controller under a class of IRDoS attack is illustrated with a numerical example.
