    There has been a growing interest in the HLA proposal as a common framework for real-time, distributed and interactive simulations. Although most of HLA compliant federates are for the moment developed with general purpose languages, the development of HLA federates with an existing simulation language would enable the rapid porting of a large number of existing simulations into the HLA framework....

    This paper describes a variant of the actor model suited to the development of multimedia systems. The actor model centers on non-overkilling concurrency and customizable constraint-directed scheduling. A distributed multimedia system consists of a collection of actors interacting with one another to fulfil a common goal, e.g., interactive videoconference, video recording on-demand, etc. Timing sy...

    Serialization, the traditional method of resolving concurrent interactions, is often inappropriate; when interactions are dependent on each other, other policies for resolving them may be more suitable. We use semantic information to help categorize common interactions encountered in the modeling and simulation domain. This categorization enables us to suggest reasonable policies for resolving the... View full abstract»

    This paper addresses the need for reliable multicast (RM) network support for the class of distributed virtual simulations (DVS) that operate with human participants who experience a virtual representation in real time, for example DIS and real-time HLA federations. The need for RM in DVS is explained. The state of reliable multicast networking is explained and typical mechanisms for providing it ... View full abstract»

    Simulation of particle systems is time consuming. However, many particle system applications require fast interactive animations. For example, simulation of physically realistic complex dust behaviors is very useful in training, education, art, advertising, and entertainment. There are no published models for real-time simulation of dust behavior generated by a traveling vehicle. In this paper we ... View full abstract»

    With the advent of standardization efforts such as the High Level Architecture (HLA) and Distributed Interactive Simulation (DIS), inter-operability of military simulation models has emerged as the chief design requirement. By enforcing strict conformance to the DIS and/or HLA, the Defense Modeling and Simulation Office (DMSO) has so far been able to “mix-and-match” different simulatio... View full abstract»

    This paper introduces a collaborative virtual environment (CVE) system over the Internet. A Virtual Reality Modeling Language (VRML) 97-based user interface is developed to permit users to navigate around the virtual world. Voice-enabled interactive agents provide a more natural interface to help users interact with each other and with the virtual world. Real-time interactions between entities in ...

  • An approach for stream transmission over HLA-RTI in Distributed Virtual Environments

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (364 KB)

    The HLA-RTI provides a general-purpose network communications mechanism for Distributed Virtual Environments (DVE) but does not provide a stream transmission mechanism directly. This paper introduces a solution for stream transmission over RTI. This solution uses RTI-APIs sendInteraction() and receiveInteraction() to transfer stream data and uses the operating system interval timer to control sche... View full abstract»

    We have developed a distributed air traffic controller simulator to study High Level Architecture (HLA) and services that are provided by the Runtime Infrastructure (RTI), especially Object Management and Ownership Management. In our simulation model, each airport is represented by a federate and controls a set of aircraft. The control of the aircraft is transferred among airports as the aircraft ... View full abstract»

    The paper describes the design and implementation of a security architecture for a HLA/RTI prototype developed at ONERA/CERT. The major security objective is to protect the intellectual property of firms participating in a distributed interactive simulation. We describe the techniques used to implement the security services: controlled subscription lists and secure associations. We report the impa... View full abstract»

    With the increasing complexity and scale of the simulation, meeting the communication and bandwidth requirements has become a major challenge in the design and implementation of Distributed Interactive Simulations (DIS). In this paper, we will study some packet bundling mechanisms as an important technique in reducing the packet transmission rate and bandwidth requirement at the gateway in a DIS e...

    Virtual spaces based on the metaphor of “shared network places” are becoming a well accepted implementation approach for multiuser, multimedia, distributed cooperative work environments to support the work activities and interactions of goal oriented business teams. Similar to real-life physical team rooms, which provide a permanent shared space used by a work group, TEAMWORKPLACE, the... View full abstract»

    Collaborative Virtual Environments are virtual reality spaces that enable participants to collaborate and share objects as if physically present in the same place. These collaboration spaces require strict performance characteristics. Today there are many systems developed specifically for collaboration, including DIVE, CALVIN, and COVEN. At the same time, some relatively new standards that addres... View full abstract»
