H-infinity based active queue management design for congestion control in computer networks

الملخص EN

In this paper the design of robust Active Queue Management (AQM) for congestion control in computer networks is presented.

The Ant Colony Optimization (ACO) method is used to tune the parameters of PID controller subject to H-infinity constraints.

The nonlinear dynamic model for multiple TCP flows control is developed based on fluid-flow theory.

The designed controller provides good tracking performance in the presence of wide range of system parameter uncertainty.

NS2 package is used to perform the nonlinear simulation of the system.
