Comparison of PI controllers designed for the delay model of TCP/AQM networks
Ünal, Hakkı Ulaş; Melchor-Aguilar, Daniel; Ustebay, Deniz; Niculescu, Silviu-Iulian; Özbay Hitay (Elsevier Science BV, 2013)One of the major problems of communication networks is congestion. In order to address this problem in TCP/IP networks, Active Queue Management (AQM) scheme is recommended. AQM aims to minimize the congestion by regulating ... -
Decentralised robust flow controller design for networks with multiple bottlenecks
Munyas, İnci; Yelbasi, özen; Biberovic, Enis; İftar, Altuğ; Özbay Hitay (Taylor & Francis LTD, 2009)Decentralised rate-based flow controller design in multi-bottleneck data-communication networks is considered. An H problem is formulated to find decentralised controllers which can be implemented locally at the bottleneck ... -
Rate-based flow controllers for communication networks in the presence of uncertain time-varying multiple time-delays
Quet, PF; Ataşlar, B; İftar, Altuğ; Özbay Hitay; Kalyanaraman, S; Kang, T (Pergamon-Elsevier Science LTD, 2002)An H-infinity based robust controller is designed for a rate-feedback flow-control problem in single-bottleneck communication networks. The controller guarantees stability robustness to uncertain time-varying multiple ... -
Robust flow control in data-communication networks with multiple time-delays
Ünal, Hakkı Ulaş; Ataşlar-AyyIldız, Banu; İftar, Altuğ; Özbay Hitay (Wiley, 2010)Robust controller design for a flow control problem where uncertain multiple time-varying time-delays exist is considered. Although primarily data-communication networks are considered, the presented approach can also be ...
