      Adaptive agent negotiation via argumentation 

      Kakas, Antonis C.; Moraïtis, Pavlos (2006)
      In this paper, we study how argumentation can be used as a basis for negotiation between autonomous agents, where negotiation strategies of the different parties are represented as argumentation theories within their ...

      Facets of the fully mixed nash equilibrium conjecture 

      Feldmann, R.; Mavronicolas, Marios; Pieris, Andreas (2008)
      In this work, we continue the study of the many facets of the Fully Mixed Nash Equilibrium Conjecture, henceforth abbreviated as the FMNE Conjecture, in selfish routing for the special case of n identical users over two ...

      Fast backward predictive congestion notification for ATM networks with significant propagation delays 

      Hu, Xiying; Lambert, James F.; Pitsillides, Andreas (1995)
      A fast Backward Predictive Congestion Notification (BPCN) scheme for ATM networks is proposed, whose objective is to avoid cell loss and achieve high resource utilisation during high traffic demand. A dynamic adaptive model ...

      Feedback control utilizing packet dropping network links 

      Hadjicostis, Christoforos N.; Touri, R. (2002)
      The increasing availability of network connectivity has prompted the study of computer-based control methodologies that are implemented centrally or distributively using existing network infrastructure as the communications ...

      Fuzzy backward congestion notification (FBCN) congestion control in asynchronous transfer mode (ATM) networks 

      Pitsillides, Andreas; Sekercioglu, Y. Ahmet; Ramamurthy, Gopalakrishnan (IEEE, 1995)
      In this paper, we study the performance of a fuzzy control scheme as a first step to develop better control strategies for avoiding congestion and attaining high link utilisation in ATM based networks. Due to the complexity ...

      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 ...

      The price of anarchy for polynomial social cost 

      Gairing, M.; Lücking, T.; Mavronicolas, Marios; Monien, Burkhard (2006)
      In this work, we consider an interesting variant of the well studied KP model for selfish routing on parallel links, which reflects some influence from the much older Wardrop model [J.G. Wardrop, Some theoretical aspects ...

      The Price of Anarchy for restricted parallel links 

      Gairing, M.; Lücking, T.; Mavronicolas, Marios; Monien, Burkhard (2006)
      In the model of restricted parallel links, n users must be routed on m parallel links under the restriction that the link for each user be chosen from a certain set of allowed links for the user. In a (pure) Nash equilibrium, ...

      The price of selfish routing 

      Mavronicolas, Marios; Spirakis, Paul G. (2007)
      We study the problem of routing traffic through a congested network. We focus on the simplest case of a network consisting of m parallel links. We assume a collection of n network users

      The price of selfish routing 

      Mavronicolas, Marios; Spirakis, Paul G. (2001)
      The problem of routing in congested communication networks was studied. A noncooperative network consisting of a set of m parallel links within a game theoretic framework was considered for analysis. A collection of n ...

      Resources in process algebra 

      Lee, I.; Philippou, Anna; Sokolsky, O. (2007)
      The Algebra of Communicating Shared Resources (ACSR) is a timed process algebra which extends classical process algebras with the notion of a resource. It takes the view that the timing behavior of a real-time system depends ...

      RISE - Co-S: High performance sensor storage and co-processing architecture 

      Banerjee, A.; Mitra, A.; Najjar, W.; Zeinalipour-Yazdi, Constantinos D.; Kalogerakil, V.; Gunopulos, Dimitrios (2005)
      Low power, high performance sensor designs are of particular importance nowadays considering the plethora of emerging applications in a wide range of fields. Applications such as audio capture, FFT (Fast Fourier Transform), ...

      SenseSwarm: A perimeter-based data acquisition framework for mobile sensor networks 

      Zeinalipour-Yazdi, Constantinos D.; Andreou, Panayiotis G.; Chrysanthis, Panos K.; Samaras, George S. (2007)
      This paper assumes a set of n mobile sensors that move in the Euclidean plane as a swarm. Our objectives are to explore a given geographic region by detecting and aggregating spatio-temporal events of interest and to store ...

      Stochastic power control for wireless networks via SDEs: Probabilistic QoS measures 

      Charalambous, Charalambos D.; Djouadi, S. M.; Denic, S. Z. (2005)
      The power control of wireless networks is formulated using a stochastic optimal control framework, in which the evolution of the channel is described by stochastic differential equations (SDEs). The latter rapture the ...
