  • Thorburn, James; Li, Xi; Holub, Viliam; O'Sullivan, Patrick; Murphy, Liam; Murphy, John (2012)
    Large enterprises possess massive quantities of computing systems. The costs of running and managing these systems, and capital investments for new hardware, are significant. Optimizing the utilization of those computing ...
  • Al Hasrouty, Christelle; Autefage, Vincent; Olariu, Cristian; Magoni, Damien; Murphy, John (2016)
    Réaliser des audio-conférences de qualité sur Internet est une tâche complexe. En effet, l'hétérogénéité des terminaux mobiles et la dynamique du réseau doivent être prises en compte par les systèmes MVoIP (Multiparty VoIP) ...
  • Portillo-Domínguez, Andrés Omar; Wang, Miao; Murphy, John; Magoni, Damien (IEEE Computer Society, 2014)
    Cloud computing is causing a paradigm shift in the provision and use of software. This has changed the way of obtaining, managing and delivering computing services and solutions. Similarly, it has brought new challenges ...
  • Ghaith, Shadi; Wang, Miao; Perry, Philip; Murphy, John (Association for Computing Machinery, 2013)
    Performance regression testing is an important step in the production process of enterprise applications. Yet, analysing this type of testing data is mainly conducted manually and depends on the load applied during the ...
  • Almaguer-Angeles, Fernando; Murphy, John; Murphy, Liam; Portillo-Domínguez, Andrés Omar (IEEE Computer Society, 2019)
    Internet of Things (IoT) systems produce large amounts of raw data in the form of log files. This raw data must then be processed to extract useful information. Machine Learning (ML) has proved to be an efficient technique ...
  • Buda, Teodora Sandra; Cerqueus, Thomas; Murphy, John; Kristiansen, Morten (Springer, 2013)
    Database sampling has become a popular approach to handle large amounts of data in a wide range of application areas such as data mining or approximate query evaluation. Using database samples is a potential solution ...
  • Ngoc-Nha, Vi Tran; Djahel, Soufiene; Murphy, John (2012)
    Vehicle routing problem (VRP) is a generic name referring to optimization problems in transportation, distribution and logistics industry. They mainly focus on serving a number of customers by a number of vehicles. Route ...
  • Arif, Saima; Wang, Miao; Perry, Philip; Murphy, John (2013)
    Bugs in a project, at any stage of Software life cycle development are costly and difficult to find and fix. Moreover, the later a bug is found, the more expensive it is to fix. There are static analysis tools to ease ...
  • Hava, Adriana; Muntean, Gabriel-Miro; Murphy, John (IEEE Computer Society, 2016)
    The continuous growth in user demand for highquality rich media services puts pressure on Wireless Mesh Network (WMN) resources. Solutions such as those which increase the capacity of the mesh network by equipping mesh ...
  • Li, Xi; Ventresque, Anthony; Murphy, John; Thorburn, James (IEEE Computer Society, 2014)
    Data center optimization, mainly through virtual machine (VM) placement, has received considerable attention in the past years. A lot of heuristics have been proposed to give quick and reasonably good solutions to this ...
  • Djahel, Soufiene; Zhang, Zonghua; Naït-Abdesselam, Farid; Murphy, John (IEEE Computer Society, 2012)
    In this paper, we deal with backoff cheating technique in IEEE802.11 based MANETs and propose a novel scheme, dubbed HsF-MAC (Hash Function based MAC protocol), to cope with it. In contrast to the existing solutions, ...
  • Ngoc-Nha, Vi Tran; McDonagh, Patrick; Murphy, John (2013)
    Acoustic data is a potential source for traffic monitoring due to its low-cost and the ease of deployment. In this paper, a case study of using acoustic monitoring as a source for transportation management purposes is ...
  • Brahmi, Imane Horiya; Djahel, Soufiene; Murphy, John (IEEE Computer Society, 2013)
    The main wireless technology used for events sensing and data collection is wireless sensor devices. These sensors are mounted on vehicles or in the roadside to send data collected periodically or upon incident detection. ...
  • Li, Xi; Ventresque, Anthony; Stokes, Nicola; Thorburn, James; Murphy, John (IEEE Computer Society, 2013)
    Server consolidation is an important problem in any enterprise, where capital allocators (CAs) must approve any cost saving plans involving the acquisition or allocation of new assets and the decommissioning of inefficient ...
  • Portillo-Domínguez, Andrés Omar; Murphy, John; O'Sullivan, Patrick (2012)
    This paper offers an overview of the performance engineering field, including some of its latest challenges. Then, it briefly describes the research area of enhancing the performance of JEE systems through leveraging its ...
  • Portillo-Domínguez, Andrés Omar; Wang, Miao; Magoni, Damien; Perry, Philip; Murphy, John (IEEE Computer Society, 2014)
    Modern computer applications, especially at enterprise-level, are commonly deployed with a big number of clustered instances to achieve a higher system performance, in which case single machine based solutions are less ...
  • Ghaith, Shadi; Wang, Miao; Perry, Philip; Murphy, John (IEEE Computer Society, 2013)
    Performance evaluation through regression testing is an important step in the software production process. It aims to make sure that the performance of new releases do not regress under a field-like load. The main outputs ...
  • Saber, Takfarinas; Ventresque, Anthony; Murphy, John (IEEE Computer Society, 2013)
    More and more drivers use on-board units to help them navigate in the increasing urbanised environment they live and work in. These system (e.g., routing applications on smart phones) are now very often on-line, and use ...
  • Holub, Viliam; Parsons, Trevor; O'Sullivan, Patrick; Murphy, John (Association for Computing Machinery, 2009)
    We present an approach and implementation for run-time correlation of large volumes of log data and symptom matching of know issues in the context of large enterprise applications. Our solution provides for (a) automatic ...
  • Iglesias, Jesus Omana; Thorburn, James; Parsons, Trevor; Murphy, John; O'Sullivan, Patrick (IEEE Computer Society, 2011)
    Understanding system utilization is currently a difficult challenge for industry. Current monitoring tools tend to focus on monitoring critical servers and databases within a narrow technical context, and have not been ...
