A Dynamic Defense Modeling and Simulation Methodology using Semantic Web Services

Abstract

Defense Modeling and Simulations require interoperable and autonomous federates in order to fully simulate complex behavior of war-fighters and to dynamically adapt themselves to various war-game events, commands and controls. In this paper, we propose a semantic web service based methodology to develop war-game simulations. Our methodology encapsulates war-game logic into a set of web services with additional semantic information in WSDL (Web Service Description Language) and OWL (Web Ontology Language). By utilizing dynamic discovery and binding power of semantic web services, we are able to dynamically reconfigure federates according to various simulation events. An ASuW (Anti-Surface Warfare) simulator is constructed to demonstrate the methodology and successfully shows that the level of interoperability and autonomy can be greatly improved.
