Event-triggered control for active queue management

For the congestion problem in TCP network, active queue management algorithm based on event-triggered control is proposed. Considering the characteristics of TCP network model, the uncertainties in the model are considered. A method to co-design of event-triggered condition and controller for the control system is proposed. And a sufficient condition which guarantees the stability of the control system is given based on the Lyapunov theory and linear matrix inequality (LMI) approach. Finally, the efficiency of the algorithm is demonstrated through a simulation example.
