Research on Extended HLA Technique Based on Meta-MDA

HLA has not HLA uniformed modeling frame for constructing federates from general simulation models, and its all of federates are au pair, i.e. it is planar architecture essentially, so related models are difficult to enter the federations with different FOM dynamically. As a result, model reusing in federate level is static reusing. MDA based HLA with two levels frame (FIA/FEI) was proposed. At first, the schema of MDA integrated HLA was discussed, then the resource management federate was specified, which broke through the plane architecture of existing HLA and supports the management of meta-models, dynamic configuration of FOM information, and dynamic creation of simulation application federate based on meta-models. This two level frame realizes meta-model based resource reusing and sharing, improving the reusing ability and sharing ability of the model resources for HLA. The application practice verifies the feasibility of double level frame.
