      Algorithmic mechanisms for internet-based master-worker computing with untrusted and selfish workers 

      Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A. (2010)
      We consider Internet-based master-worker computations, where a master processor assigns, across the Internet, a computational task to a set of untrusted worker processors, and collects their responses

      CDNs content outsourcing via generalized communities 

      Katsaros, Dimitrios S.; Pallis, George C.; Stamos, Kostas; Vakali, Athena I.; Sidiropoulos, Antonis; Manolopoulos, Yannis (2009)
      Content distribution networks (CDNs) balance costs and quality in services related to content delivery. Devising an efficient content outsourcing policy is crucial since, based on such policies, CDN providers can provide ...

      CDNsim: A simulation tool for content distribution networks 

      Stamos, Kostas; Pallis, George C.; Vakali, Athena I.; Katsaros, Dimitrios S.; Sidiropoulos, Antonis; Manolopoulos, Yannis (2010)
      Content distribution networks (CDNs) have gained considerable attention in the past few years. Hence there is need for developing frameworks for carrying out CDN simulations. In this article we present a modeling and ...

      Coordination and control of distributed energy resources for provision of ancillary services 

      Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2010)
      This paper discusses the utilization of distributed energy resources on the distribution side of the power grid to provide a number of ancillary services. While the individual capability of these resources to provide grid ...

      Distributed Finite-Time Computation of Digraph Parameters: Left-Eigenvector, Out-Degree and Spectrum 

      Charalambous, T.; Rabbat, M. G.; Johansson, M.; Hadjicostis, Christoforos N. (2016)
      Many of the algorithms that have been proposed in the field of distributed computation rely on assumptions that require nodes to be aware of some global parameters. In this paper, we propose algorithms to compute some ...

      HelperCoreDB: Exploiting multicore technology to improve database performance 

      Papadopoulos, Kostas; Stavrou, Kyriakos; Trancoso, Pedro (2008)
      Due to limitations in the traditional microprocessor design, such as high complexity and power, all current commercial high-end processors contain multiple cores on the same chip (multicore). This trend is expected to ...

      Mobile commerce: Vision and challenges (location and its management) 

      Samaras, George S. (Institute of Electrical and Electronics Engineers Inc., 2002)
      Mobile computing is distributed computing that involves elements whose location changes in the course of computation. Elements may be software components such as mobile agents or moving objects-data or hardware such as ...

      On the practicality of atomic MWMR register implementations 

      Nicolaou, Nicolas C.; Georgiou, Chryssis (2012)
      In this work we conduct an experimental performance evaluation of four MWMR atomic register implementations: SFW from [8], APRX-SFW and CWFR from [11], and SIMPLE (the generalization of [5] in the MWMR environment). We ...

      Real-time coordination in distributed multimedia systems 

      Limniotes, Theophilos A.; Papadopoulos, George Angelos (2000)
      The coordination paradigm has been used extensively as a mechanism for software composition and integration. However, little work has been done for the cases where the software components involved have real-time requirements. ...

      Supervisory control strategies for enhancing system security and privacy 

      Hadjicostis, Christoforos N. (2010)
      Enhancing the security and reliability of automated systems that control vital national infrastructures, such as energy and water distribution systems, has recently emerged as a critical aspect of maintaining, protecting, ...
