A Web-based 3D War-Gaming Simulation Built on HLA Distributed Architecture

Abstract

This paper describes the design of High Level Architecture (HLA) distributed architecture to support an interactive, interoperable, and collaborative war-gaming simulation using Java technology and IEEE standard 1516 – HLA. Based on the Run-Time Infrastructure (RTI) services which are specified in HLA and Java applica1ion programming interface (API) of the RTI, the proposed distributed virtual environment (DVE) provides a practical foundation to enhance interactivity, portability, and interoperability for Web-based distributed simulation. In addition, a dynamic load-sharing strategy is adopted to deal with load imbalance problem occurred in the HLA federation. Moreover, we build up a 3D synthetic virtual world for aircraft simulator by means of Java 3D API in which Java 3D technology could support a simple, portable, and flexible programming model for 3D scene construction on the Web. From the system implementation and experimental results, we show that the proposed HLA distributed architecture is a practical and scalable design that is applicable for a wide variety of moderate DVEs.
