    • Self-adapting context definition 

      CAHILL, VINNY (2007)
      Many approaches to context-aware computing have focused on providing means for developers to define application contexts. In these approaches, correct application behavior depends on the developer defining the right contexts. ...

    • Security considerations in a network management environment 

      O'MAHONY, DONAL EDWARD (IEEE, 1994)
      Considers the security aspects of communication between two management processes operating in different management domains; identifies two major risks: the security of information exchanged during the management association, ...

    • Introducing security aspects with model transformation 

      FOX, JORGE; Jurjens, Jan (IEEE Computer Society, 2005)
      Aspect Oriented Programming and subsequently Aspect Oriented Software Development have received great attention recently and constitutes an interesting field of research in computer science. The goal of this paper is ...

    • Overlay networks : a scalable alternative for P2P 

      O'MAHONY, DONAL EDWARD; Doval, D. (IEEE, 2003)
      Overlay networks create a structured virtual topology above the basic transport protocol level that facilitates deterministic search and guarantees convergence. Overlay networks are evolving into a critical component for ...

    • Performance analysis of cryptographic protocols on handheld devices 

      O'Mahony, Donal; Tewari, Hitesh (IEEE, 2004)

    • Instant messaging and presence management in mobile ad-hoc networks 

      O'MAHONY, DONAL EDWARD; Greene, D. (IEEE, 2004)
      The combination of real-time message delivery and presence awareness has to lead the rapid rise in popularity of Instant Messaging (IM) in recent years. The extension of IM to mobile ad-hoc networks certainly offers ...

    • Secure routing for mobile ad-hoc networks 

      ARGYROUDIS, PATROKLOS; O'MAHONY, DONAL EDWARD (IEEE, 2005)
      In this article we present a survey of secure ad hoc routing protocols for mobile wireless networks. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing ...

    • A cost analysis of optical IP switching in new generation optical networks 

      DOYLE, LINDA; O'MAHONY, DONAL EDWARD; Ruffini, M. (IEEE, 2006)
      In this paper we propose a simple model that analyzes the cost saving achieved by optical IP switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects ...

    • Cognitive radio: value creation and value migration 

      DOYLE, LINDA; NOLAN, KEITH EDWARD; O'MAHONY, DONAL EDWARD; Ambrose, E. (2006)
      This paper develops the concept of a telecommunications value-chain and explores the many ways in which the valuechain can be altered by reconfigurable software-defined radios, cognitive radios and cognitive networks. ...

    • Feasibility of flow-based optical provisioning in GEANT 

      DOYLE, LINDA; O'MAHONY, DONAL EDWARD; Ruffini, M. (Optical Society of America, 2007)
      We present a novel network architecture that establishes dynamic optical paths by analyzing local network traffic. We demonstrate its feasibility and effectiveness through a network analysis using real traces collected ...

    • A policy-driven trading framework for market-based spectrum assignment 

      ARGYROUDIS, PATROKLOS; DOYLE, LINDA; FORDE, TIM; O'MAHONY, DONAL EDWARD (IEEE, 2007)
