      Locating objects in mobile computing 

      Pitoura, Evaggelia 1967-; Samaras, George S. (2001)
      In current distributed systems, the notion of mobility is emerging in many forms and applications. Mobility arises naturally in wireless computing since the location of users changes as they move. Besides mobility in ...

      MPI-FT: Portable fault tolerance scheme for MPI 

      Louca, Soulla P.; Neophytou, Neophytos; Lachanas, Adrianos; Evripidou, Paraskevas (2000)
      In this paper, we propose the design and development of a fault tolerant and recovery scheme for the Message Passing Interface (MPI). The proposed scheme consists of a detection mechanism for detecting process failures, ...

      Optimal control approach to dynamic bandwidth allocation in B-ISDN 

      Pitsillides, Andreas; Lambert, J. (Publ by IE Aust, 1992)
      Asynchronous Transfer Mode (ATM) will be the transfer mode for implementing Broadband-ISDN (B-ISDN). This is prompted by the need to handle a variety of types of services, with diverse demands on the network in terms of ...

      Performance evaluation of mobile IPv6 handover extensions in an IEEE 802.11b wireless network environment 

      Lai, J.; Sekercioglu, Y. Ahmet; Jordan, N.; Pitsillides, Andreas (2006)
      In order to support mobile users, the basic Internet protocols have been extended with protocols (e.g., Mobile IPv6) for intercepting and forwarding packets to a mobile and possibly roaming node. Seamless roaming requires ...

      Personalized portals for the wireless and mobile user 

      Panayiotou, Christoforos; Samaras, George S. (2003)
      The Wireless environment requires new type of services and new ways for structuring the needed content. Personalization comes into aid via the creation of personalized portals that directly tones down factors that break ...

      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 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 ...

      RC-BB switch a high performance switching network for B-ISDN 

      Chen, Hongxu; Lambert, Jim; Pitsillides, Andreas (1995)
      Multistage networks are strong candidates for implementation of ATM switching fabrics in B-ISDN networks. Among a number of proposed multistage networks, the Banyan network with its self-routing property, modular structure ...

      A simple roadway control system for freeway traffic 

      Zhang, J.; Chang, H.; Ioannou, Petros A. (2006)
      In this paper, a roadway control system that regulates variable speed limits along the freeway in addition to ramp metering is proposed to counteract traffic congestion and improve freeway efficiency. It treats the speed ...

      Structuring topologically aware overlay networks using domain names 

      Zeinalipour-Yazdi, Constantinos D.; Kalogeraki, Vana (2006)
      Overlay networks are application layer systems which facilitate users in performing distributed functions such as searches over the contents of other users. An important problem in such networks is that the connections ...

      A Study on Workload Characterization for a Web Proxy Server 

      Pallis, George C.; Vakali, Athena I.; Angelis, Lefteris; Saïd Hacid, M. (2003)
      The popularity of the World-Wide-Web has increased dramatically in the past few years. Web proxy servers have an important role in reducing server loads, network traffic, and client request latencies. This paper presents ...

      Two-phase commit optimizations in a commercial distributed environment 

      Samaras, George S.; Britton, K.; Citron, A.; Mohan, C. (1995)
      An atomic commit protocol can ensure that all participants in a distributed transaction reach consistent states, whether or not system or network failures occur. The atomic commit protocol used in industry and academia is ...

      VITP: An information transfer protocol for vehicular computing 

      Dikaiakos, Marios D.; Iqbal, S.; Nadeem, T.; Iftode, L. (2006)
      Recent advances in wireless inter-vehicle communication systems enable the development of Vehicular Ad-Hoc Networks (VANET) and create significant opportunities for the deployment of a wide variety of vehicular applications ...
