Abstract

In order to make the best utilization of a link in computer networks, Active Queue Management (AQM) algorithms are generally used in a variety of methods. In this paper, a systematic control strategy based on self-scheduled H_∞, considering the dynamics of the window-based TCP flow, is proposed. Then, the robustness of the designed controller to disturbance and parameter fluctuations of the plant is shown via simulation results.

Keywords - AQM, Congestion Control, ATM, TCP, Robust, LMI, Window-Based.
