Adaptive nonlinear congestion controller for a differentiated-services framework
Pitsillides, Andreas; Ioannou, Petros A.; Lestas, Marios; Rossides, Loukas (2005)The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In ...

Adaptive notch filter using real-time parameter estimation
Levin, J.; Pérez-Arancibia, N. O.; Ioannou, Petros A. (2011)The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation ...

Adaptive optimization for active queue management supporting TCP flows
Baldi, S.; Kosmatopoulos, E. B.; Pitsillides, Andreas; Lestas, Marios; Ioannou, Petros A.; Wan, Y. (Institute of Electrical and Electronics Engineers Inc., 2016)An adaptive decentralized strategy for active queue management of TCP flows over communication networks is presented. The proposed strategy solves locally, at each link, an optimal control problem, minimizing a cost composed ...
