      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 ...

      A congestion control algorithm for max-min resource allocation and bounded queue sizes 

      Lestas, Marios; Ioannou, Petros A.; Pitsillides, Andreas (2004)
      This paper deals with the congestion control problem in computer networks which is viewed as a resource allocation problem constrained by the additional requirement that the queue sizes need to be bounded. We propose a ...

      Fuzzy explicit marking: A unified congestion controller for Best-Effort and Diff-Serv networks 

      Chrysostomou, Chrysostomos; Pitsillides, Andreas; Sekercioglu, Y. Ahmet (2009)
      This paper, proposes a generic active queue management (AQM) control methodology in TCP/IP networks, based on Fuzzy logic control principles. A simple, effective and efficient non-linear control law is built, using a ...

      Fuzzy logic congestion control in TCP/IP differentiated services networks for quality of service provisioning 

      Chrysostomou, Chrysostomos; Pitsillides, Andreas; Hadjipollas, George; Sekercioglu, Y. Ahmet; Polycarpou, Marios M. (2004)
      A two class Fuzzy Explicit Marking (FEM) controller was designed and used in Differentiated Services Networks for quality of service provisioning. The fuzzy control system is designed to regulate the queues of IP routers ...

      The impact of network structure on the stability of greedy protocols 

      Koukopoulos, D.; Mavronicolas, Marios; Nikoletseas, Sotiris E.; Spirakis, Paul G. (2003)
      A packet-switching network is stable if the number of packets in the network remains bounded at all times. A very natural question that arises in the context of stability and instability properties of such networks is how ...

      The increase of the instability of networks due to Quasi-Static link capacities 

      Koukopoulos, D.; Mavronicolas, Marios; Spirakis, Paul G. (2007)
      In this work, we study the impact of the dynamic changing of the network link capacities on the stability properties of packet-switched networks. Especially, we consider the Adversarial, Quasi-Static Queuing Theory model, ...

      Packet scheduling over a wireless channel: AQT-based constrained jamming 

      Fernández Anta, Antonio; Georgiou, Chryssis; Zavou, Elli (2015)
      In this paper we consider a two-node setting with a sender transmitting packets to a receiver over a wireless channel. Unfortunately, the channel can be jammed, thus corrupting the packet that is being transmitted at the ...

      Performance and stability bounds for dynamic networks 

      Koukopoulos, D.; Mavronicolas, Marios; Spirakis, Paul G. (2004)
      In this work, we study the impact of dynamically changing link capacities on the delay bounds of LIS (Longest-In-System) and SIS (Shortest-In-System) protocols on specific networks (that can be modelled as Directed Acyclic ...
