      Adaptive packet scheduling over a wireless channel under constrained jamming 

      Fernández Anta, Antonio; Georgiou, Chryssis; Kowalski, D. R.; Zavou, Elli (2017)
      In this work we consider the communication over a wireless link, between a sender and a receiver, being disrupted by a jammer. The objective of the sender is to transmit as much data as possible to the receiver in the most ...

      Adaptive scheduling over a wireless channel under constrained jamming 

      Fernández Anta, Antonio; Georgiou, Chryssis; Zavou, Elli (2015)
      We consider a wireless channel between a single pair of stations (sender and receiver) that is being “watched” and disrupted by a malicious, adversarial jammer. The sender’s objective is to transmit as much useful data as ...

      Adaptive sliding mode control of a hypersonic flight vehicle 

      Xu, H.; Leung, P.; Mirmirani, M.; Boussalis, Helen R.; Ioannou, Petros A. (2001)
      A Multi Input Multi Output (MIMO) adaptive sliding controller is designed and analyzed for the longitudinal dynamics of a generic hypersonic air vehicle. This vehicle model is highly nonlinear, multivariable, unstable and ...

      ADIVIS: A novel adaptive algorithm for video streaming over the internet 

      Antoniou, Pavlos Ch.; Vassiliou, Vasos; Pitsillides, Andreas (2007)
      The transfer of information over the wireless networks is emerging as a promising business model. In addition, new applications require the transfer of video content in real time. However, the unpredictable nature of ...

      Dynamical neural networks that ensure exponential identification error convergence 

      Kosmatopoulos, E. B.; Christodoulou, Manolis A.; Ioannou, Petros A. (1997)
      Classical adaptive and robust adaptive schemes, are unable to ensure convergence of the identification error to zero, in the case of modeling errors. Therefore, the usage of such schemes to 'black-box' identification of ...

      An indirect adaptive control design with anti-windup compensation: Stability analysis 

      Kahveci, N. E.; Ioannou, Petros A. (2007)
      We combine an adaptive law with a control design including a Linear Quadratic (LQ) controller and a Linear Matrix Inequality (LMI) based anti-windup compensator using the certainty equivalence principle for asymptotically ...

      Mobile station position and velocity computerbased Estimation using adaptive algorithms and Smart antennas 

      Papadimitriou, D.; Vardiambasis, I. O.; Melesanaki, T.; Vardiambasis, K. (University of Cyprus, 2007)
      The increasing demand for mobile communication services without a corresponding increase in radio frequency spectrum allocation motivates the need for new techniques to improve spectrum utilization. An approach that shows ...

      On the complexity of asynchronous gossip 

      Georgiou, Chryssis; Gilbert, S.; Guerraoui, R.; Kowalski, D. R. (2008)
      In this paper, we study the complexity of gossip in an asynchronous, message-passing fault-prone distributed system. In short, we show that an adaptive adversary can significantly hamper the spreading of a rumor, while an ...
