  • Dobson, Simon; Neely, Steve; Nixon, Paddy (Springer, 2006)
    The increasingly dynamic nature of resource discovery and binding in modern large-scale distributed and mobile systems poses significant challenges for existing middleware platforms. Future platforms must provide strong ...
  • Cahill, Vinny; Baker, Sean; Nixon, Paddy (IEEE Computer Society, 1997)
    peer-reviewed applications that cross the boundaries of different computing machines, operating systems, and programming languages are increasingly the norm. As a result, the need for what might be called “bridging ...
  • Razzaque, Mohammed Abhur; Dobson, Simon; Nixon, Paddy (American Scientific Publishers, 2006)
    Pervasive computing environments are dynamic and heterogeneous. They are required to be self-managing and autonomic, demanding minimal user’s guidance. In pervasive computing, contextaware adaptation is a key concept ...
  • Razzaque, Mohammed Abhur; Dobson, Simon; Nixon, Paddy (IEEE Computer Society, 2007)
    Pervasive and autonomic environments make extensive use of contextual information to guide adaptations to changing external demands and circumstances. Context takes many forms, and some form of categorisation of information ...
  • Shannon, Ross; Quigley, Aaron; Nixon, Paddy (Association for Computing Machinery, 2006)
    As visualizations of large systems get more and more complex, larger collaborative spaces are required so that a team of designers may work together while visualising their system. This paper describes the outfitting ...
  • Gaudin, Benoit; Vassev, Emil; Hinchey, Mike; Nixon, Paddy (Association for Computing Machinery, 2011)
    This work presents an approach to self-healing that deals with un-handled exceptions within an executing program. More precisely, we propose an approach based on control theory that automatically disables system functionalities ...
  • Razzaque, Mohammed Abhur; Dobson, Simon; Nixon, Paddy (Springer, 2007)
    Layered architectures are not flexible enough to cope with the dynamics of wireless dominated next generation communications. Cross-layer architectures may provide a more flexible solution: breaks the traditional structure ...
  • Vassev, Emil; Hinchey, Mike; Nixon, Paddy (Association for Computing Machinery, 2010)
    We present a technological convergence approach to developing sensor networks capable of self-management. We use ASSL (Autonomic System Specification Language) to formally develop autonomous intelligent sensor nodes and ...
  • Gaudin, Benoit; Vassev, Emil; Hinchey, Mike; Nixon, Paddy; Coelho, Garcia J.; Maalej, Walid (Szkoła Wyższa Psychologii Społecznej (SWPS), 2012)
    One of the main objectives of self-adaptive systems is to reduce maintenance costs through automatic adaptation. Self-healing is a self-adapting property that helps systems return to a normal state after a fault or ...
  • Vassev, Emil; Hinchey, Mike; Nixon, Paddy (IEEE Computer Society, 2010)
    Intelligent swarms draw their inspiration from biology where many simple entities act independently, but when grouped, they appear to be highly organized. NASA is currently investigating swarm-based technologies for the ...
  • Dobson, Simon; Sterritt, Roy; Nixon, Paddy; Hinchey, Mike (IEEE Computer Society, 2010)
    Efforts since 2001 to design self-managing systems have yielded many impressive achievements, yet the original vision of autonomic computing remains unfulfilled. Researchers must develop a comprehensive systems engineering ...
  • Shannon, Ross; Quigley, Aaron; Nixon, Paddy (Association for Computing Machinery, 2010)
    Network visualisations use clustering approaches to simplify the presentation of complex graph structures. We present a novel application of clustering algorithms, which controls the visual arrangement of the vertices in ...
  • Dobson, Simon; Nixon, Paddy; Coyle, Lorcan (IEEE Computer Software Society, 2007)
    Event-based systems are a popular substrate for distributing information derived from sensors to be used in driving adaptive behaviour. This paper argues that using events directly provides a poor model of context, and ...
  • Dobson, Simon; Nixon, Paddy (Trinity College Dublin, Dept. of Computer Science, 1999)
    We are currently witnessing a convergence of several threads of technology and business imperatives. The idea of a virtual enterprise (VE) – a business built from both organizationally and geographically distributed units ...
  • Dobson, Simon; Stevenson, Graeme; Knox, Stephen; Nixon, Paddy (Association for Computing Machinery, 2009)
    Pervasive systems present the need to interpret large quantities of data from many sources. Context models support developers working with such data by providing a shared representation of the environment on which to base ...
  • Dobson, Simon; Nixon, Paddy (IEEE Computer Society, 2008)
    Treating autonomic systems as solving individual, isolated problems misses the opportunity to consider adaptation as an object of study in its own right. We propose a grand challenge of supporting adaptation in an open ...
  • Vassev, Emil; Hinchey, Mike; Nixon, Paddy (Association for Computing Machinery, 2010)
    We target effective home automation based on wireless sensor networks. ASSL (Autonomic System Specification Language) is used to formally specify and generate prototype models for wireless sensor networks controlling a ...
  • Vassev, Emil; Hinchey, Mike; Gaudin, Benoit; Nixon, Paddy (Association for Computing Machinery, 2011)
    Autonomic Service-Component Ensembles (ASCENS) is a class of multi-agent systems formed as mobile, intelligent and open-ended swarms of special autonomic service components capable of local and distributed reasoning. Such ...
  • Clarke, Siobhán; Fitzgerald, Brian; Nixon, Paddy; Pohl, Klaus; Ryan, Kevin; Sinclair, David; Thiel, Steffen (SAE International, 2008)
    The amount and complexity of software in automotive systems is constantly increasing. Today’s luxury cars include numerous electronic control units. A large part of the functionality of these units is driven by software. In ...
  • Williamson, Graham; Cellai, Davide; Dobson, Simon; Nixon, Paddy (Springer, 2009)
    Many modern network applications, including sensor networks and MANETs, have dynamic topologies that reflect processes occurring in the outside world. These dynamic processes are a challenge to traditional information ...
