Abstract

As M&S (Modeling and Simulation) systems are developed in National Defense field, demand of sharing and managing simulation data in real-time during simulation is increasing. Simulation data is interchanged as FOM (Federation Object Model) type through the standard interoperation system, HLA/RTI (High Level Architecture / Real-Time Infrastructure). Guaranteeing real-time performance during M&S training is the most important. However, FOM type of interchanging simulation data in HLA/RTI does not ensure real-time management since FOM data is disposable that can be used only once. We suggest adding distributed DBMS to the existing HLA/RTI system to achieve the real-time interoperation of simulation data, and also design RTI-DB (Real-Time Infrastructure - DataBase) Coordinator for effective data interchange between HLA/RTI system and distributed DBMS to support real-time management of simulation data during simulation. This paper will discuss the proposed system as well as the evaluation of its potential performance.
