Distributed Event-Triggered Nash Equilibrium Seeking Under Hybrid Attacks and Dead-Zone Inputs: A Topology Reconstruction Approach

A distributed Nash equilibrium (NE) seeking algorithm is proposed for multi-agent systems under non-cooperative game settings, where players are subject to hybrid attacks composed of Denial-of-service (DoS) and false data injection (FDI) attacks. The unknown dead-zone inputs are also taken into account for each agent. An event-triggered strategy is employed to enhance communication efficiency. With a topology reconstruction scheme, the impacts of hybrid attacks are mitigated. With the proposed event-triggered NE-seeking algorithm, the convergence of the distributed NE-seeking algorithm is analyzed, and an upper bound for the DoS attack time ratio is provided. Finally, the effectiveness of the algorithm is validated through numerical simulations.
