CONGESTION TRACKING CONTROL FOR WIRELESS TCP/AQM NETWORK BASED ON ADAPTIVE DYNAMIC SURFACE SCHEME

. In order to address the Active Queue Management (AQM) issue in a wireless Transmission Control Protocol (TCP) network, the goal of this study is to develop an adaptive dynamic surface controller. This method enables the proposed control law to be applied to the nonlinear wireless network model's congestion tracking issue. A statefeedback congestion controller is additionally suggested to guarantee that the queue length can follow the target queue length despite unexpected changes and unknown parameters. The MATLAB environment is used to validate the developed control design. Simulated results are used to confirm the effectiveness of the suggested control, and it is contrasted with an adaptive integral backstepping scheme. The simulation results show that the proposed technique can not only give better transient performances, but also address the required congestion tracking control problem in spite of unknown parameters.
