Distributed Simulation of Underwater Warfare based on Standard Synthetic Environment

this paper presents a framework for underwater warfare simulation in a distributed system that is based on standard synthetic environment. The proposed framework adopts SEDRIS (Synthetic Environmental Data Representation and Interchange Specification) to represent the underwater environment in HLA (High Level Architecture) based distributed simulation systems. Although SEDRIS provides various merits as an international standard, it has never been easy to utilize SEDRIS in distributed simulation systems because of its broadness and heaviness. To relieve the difficulties, we present a practical method to utilize SEDRIS technology for underwater warfare simulation. The key idea of the paper is to extract the ‘SEDRIS structure’ dedicated to the underwater environment which is represented with 4-diemensional grid data. The extracted ‘SEDRIS structure’ can be easily adapted to HLA based distributed simulation systems requiring underwater environment. Underwater warfare simulation is implemented along with the proposed framework and it is visualized by using Delta3D simulation game engine.
