Optimal power allocation for multiple DoS attackers in wireless networked control systems
2019
Abstract In this paper, an optimal power allocation strategy for multiple denial-of-service attackers is investigated in a wireless networked control system with stochastic disturbances. In the presence of denial-of-service attackers, effective signals sent by a transmitter are interfered with causing degradation of signal-to-interference-plus-noise ratio and even packet loss. The effect of multiple attacks on the wireless networked control system is maximized by cooperative game. An H ∞ minimax controller is also designed to guarantee an optimal performance for the wireless networked control system in the worst case. A numerical example is conducted to verify the validity of the proposed methodology.
