Abstract

Simulation systems have been used in many fields of society. Training effects, budget reductions, and situation prediction can be achieved by experiencing activities in the real world through simulation. Because of these advantages, simulation systems have been used in national defense fieldsin particular. National defense simulations can be divided into three parts, live simulations, virtual simulations, and constructive simulations, and each simulation has respective features and advantages. L-V-C integrated simulation in the national defense field is becoming increasingly important because itallows a variety of operations/training scenarios to be conducted by joint training. It also improves the accuracy of training and can reduce both time and budget. However, in the case where L-V-C have heterogeneous middleware, interoperation of each middleware is necessary for integration of L-V-C. In this research, we propose ontology based interoperation between DDS (a live middleware) and HLA (a virtual middleware). For this, we constructed an ontology that has relation information of APIs and parameters between HLA and DDS, and stored the ontology in a triple store. Furthermore, we developed an ontology processing module for management of the ontology. The proposed ontology-based system allows interoperation between HLA and DDS.
