LQ-Servo Congestion Control for TCP/AQM System in Wireless Network Environment

This paper presents LQ-Servo controller for congestion control in TCP/AQM wireless networks environment using previously developed controller. A wireless networks link has a capacity which is time-varying. For this, it is modeled by three-state mode for considering the dynamics of wireless links in this paper. And the proposed controller structure is made by augmenting a new state variable to the feed-forward loop.
