      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 ...

      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 ...

      Congestion control in differentiated services networks using fuzzy logic 

      Chrysostomou, Chrysostomos; Pitsillides, Andreas; Hadjipollas, George; Polycarpou, Marios M.; Sekercioglu, Y. Ahmet (2004)
      The provision of quality of service (QoS) in a differentiated services (Diff-Serv) environment requires an adequate differentiation between high-priority/assured and low-priority/best-effort classes of service in the ...

      Content Delivery Networks: Status and Trends 

      Vakali, Athena I.; Pallis, George C. (2003)
      An insight into the content delivery networks (CDN) architecture and popular CDN service providers is performed. CDNs improve network performance and offer fast and reliable applications and services by distributing content ...

      Coordinating web services using channel based communication 

      Lemniotes, Theophilos; Papadopoulos, George Angelos; Arbab, Farhad (2004)
      In this work we investigate the use of a new concept in component communication during the coordination of Web Services, expressed by the channel based coordinating communication system called Reo. The role of Reo is to ...
