Integration of Composable Simulations with Real-time Applications and Databases

Federated simulations address the need for interoperability, as well as the improvement of reuse and composability. The focal goal in a federated simulation is to facilitate composable simulations by standardizing interfaces to assure technical interoperability among disparate simulations. Yet, existing federated simulation infrastructures neither facilitate substantive interoperability nor are dynamically extensible. Emergent semantic Grid service technologies hold out the potential to significantly improve the development of interoperable, extensible, and dynamically composable federations. As such, recent initiatives such as Extensible Modeling and Simulation Framework are urging the use of open standards that can be applied within an extensible framework for next generation modeling and simulation applications. We propose to research, design, partially prototype a run-time extensible simulation modeling infrastructure that builds on our earlier work on agent-mediated model marketplaces and dynamic composability. Contextualized introspective simulation models along with agent-based mediation, brokering, and matchmaking strategies are proposed to enable dynamic model and simulation updating at run-time. The premise of the strategy entails semantic web services in conjunction with agent technology to provide facilities for run-time model discovery, location, retrieval, composition, and interoperation.
