Computer networks have increased congestion collapse problems according to growth of wired or wireless network. This paper presents LQ-servo controller for congestion control in (Transmission Control Protocol/Active Queue Management) 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.
