MDA-Based Simulation Development of HLA

Currently, as the middleware in the distributed simulation, HLA has interoperability problems related to other similar middleware environments. To solve these reusability and interoperability problems, this paper introduces the MDA approach to the design of simulation, attempts to improve the reusability and interoperability of HLA in the whole software lifecycle by using modeling idea of MDA. Using the approach, a federate can be separated into Behavior Logic and Integration Code, and using different models to describe and map them. This approach reduces the complexity and the difficulty of integration. When we describe and map models by analyzing the differences and relations between object models of HLA and OOAD, we establish the PIM and PSM of the federate using modeling idea of MDA.
