Active queue management (AQM) for TCP/IP networks using discrete time sliding mode control (DSMC)

In order to preserve quality of service (QoS) in a computer network, implementation of traffic engineering (TE) techniques is critical to meet congestion control. In this paper a systematic control strategy based on discrete time sliding mode control considering the dynamics of the window based TCP flow is proposed. Robustness of the designed controller against disturbance and delay variations has been shown via formulas and simulation results
