    The recent emergence of dramatically large computational power, spanning desktops with multi-core processors and multiple graphics cards to supercomputers with 105 processor cores, has suddenly resulted in simulation-based solutions trailing behind in the ability to fully tap the new computational capacity. Here, we motivate the need for switching the parallel simulation research to a h... View full abstract»

    To support the evacuation process of crowds from emergency situations, we have developed a wearable device, LifeBelt, for vibro tactile guidance of individuals in panic towards exits. Since visual and auditory perception is overwhelmed in situations of panic, exit sign and loudspeaker based evacuation often appears ineffective. LifeBelt as a coordinated navigation device builds on a subtle directi... View full abstract»

    Computer simulation is an important factor in today's disaster prevention procedures. Simulation codes assess the evolution and impact of various physical phenomena in domains such as nuclear and environmental sciences, and ultimately help saving lives. However, new and more computationally demanding models, and new regulations for personnel training have increased the demand for computational pow... View full abstract»

    In parallel discrete event simulation techniques, the simulation model is partitioned into objects, concurrently executing events on different CPUs and/or multiple CPU-Cores.In such a context, run-time supports for logical time synchronization across the different simulation objects play a central role in determining the effectiveness of the specific parallel simulation environment. In this paper ... View full abstract»

    In this paper, we present and evaluate a system for performing logical-time synchronised Range Queries over data in the context of parallel and distributed simulations of Multi-Agent Systems (MAS). MAS are often extremely complex and simulation is commonly used to understand their behaviour or investigate the implications of alternative agent architectures. Range Queries are widely used in various... View full abstract»

    Interactive multi-user Internet games require frequent state updates between players to accommodate the great demand for reality and interactivity. The large latency and limited bandwidth on the Internet greatly affects the game's scalability. The High Level Architecture (HLA) is the IEEE standard for distributed simulation with its Data Distribution Management (DDM) service group assuming the fun... View full abstract»

  • An Approach for Parallel Interest Matching in Distributed Virtual Environments

    Interest management is essential for real-time large-scale distributed virtual environments (DVEs) which seeks to filter irrelevant messages on the network. Many existing interest management schemes such as HLA DDM focus on providing precise message filtering mechanisms. However, this leads to a second problem: the computational overhead of the interest matching process. If the CPU cost of interes... View full abstract»

    System rendering latency has been recognized by senior researchers, such as Professor Fredrick Brooks of UNC (Turing Award 1999), as a major factor limiting the realism and utility of head-referenced display systems. Latency has been shown to reduce the user's sense of immersion within a virtual environment, to disturb user interaction with virtual objects, and to contribute to motion sickness dur...

    Effective processing of source data matched to appropriate visualisation can greatly enhance the user's ability to explore and comprehend complex information. While this is a fundamental problem for many domains, in medical applications it is particularly important. None-invasive scanning technologies, such as MRI, have greatly enhanced our ability to `image' the internal body, however the resulta... View full abstract»

    Latency in a communication system can result in confusing a conversation through loss of causality as people exchange verbal and non-verbal nuances. This paper compares true end-to-end latencies across an immersive virtual environment and a video conference link using the same approach to measure both. Our approach is to measure end-to-end latency through filming the movements of a participant and... View full abstract»

    The construction of stable and adaptive clusters providing good performance and faster convergence rate with minimal overhead is a challenging task in Mobile Ad hoc Networks (MANETs). This paper proposes a clustering technique for MANETs, which is distributed, dominating set based, weighted and adaptive to changes in the topology called Distributed Scenario-based Clustering Algorithm for Mobile ad...

    Predicting latency between nodes on the Internet can have a significant impact on the performance of many services that use latency distances among nodes as a decision making input. Coordinate-based approaches are among the family of latency prediction techniques where latency between each pair of nodes is modeled as the virtual distance among those nodes over a virtual system.
