A distributed simulation backbone for executing HLA-based simulation over the internet

With the increase in complexity of simulations, there is a growing need for accessing large amount of computing resource and data sets which could be geographically distributed. The Grid provides an infrastructure for collaborative resource sharing to execute large-scale applications. In this paper, we propose a framework for distributed simulation using the High Level Architecture (HLA) over the Grid. The backbone makes use of a Federate-Proxy-RTI architecture, in which a remote proxy acts on behalf of the federate in interacting with RTI. This architecture hides the communication over the Grid network, and provides user transparency and simulator reusability. A prototype is implemented using DMSO’s RTI 1.3 and the Grid system runs the Globus Toolkit Version 3 to achieve compatibility and interoperability.
