Abstract

HLA, a DoD high level architecture, is emerging as a n IEEE standard platform for large-scale distributed inter- active simulation systems. It mainly emphasizes o n the reusability and interoperability of different simulation com- ponents. However, HLA/RTI shows a n apparent weak- nesses when it comes t o distributed real-time simulation applications. I n this paper, we propose a real-time RTI system, based upon a multi-threaded process model, that addresses the weakness of H L A / R T I in terms of real-time applications. W e discuss our real-time mechanism, and highlight the main design issues of our real-time RTI. W e describe its implementations, and present a n extensive set of simulation experiments to evaluate its performance us- ing realistic models.
