Constructing LVC Simulation Environments Based on Legacy Simulations

As Modeling and Simulation (M&S) developing rapidly and used widely, more complicated simulations are needed, especially in military. That distinct architectures co-exist affect the interoperability between legacy simulations. It is considered the most promising approach to construct large-scale simulation environment through inter-connecting heterogeneous systems, called multi-architectures simulation environment or LVC simulation environments. When two or more architectures exist in a simulation environment, interoperability problems raise due to the dissimilarities, covering middle ware incompatibilities, dissimilar metamodels for data exchange, and differences in the nature of the services that are provided by the architectures. The article achieves the interoperability in the level of Object Model by creating the broker for each participating system, and establishes the mapping between data in brokers and Architecture-Neutral Object Model (ANOM).
