State-Feedback Control in TCP Network: Geometric Approach
In this paper, we study the problem of congestion of a router, initially, we propose a model of TCP based on the fluid flux model and, secondly, considering frequency-domain approach, we synthesize a state-feedback control to ensure the stability of our system. This study is essentially based on the analysis of the stability of the characteristic equation associated to closed loop system with consideration of communication delays. Finally, simulation results are provided to validate the proposed methodology.
