Abstract

In a large-scale simulation Data Distribution Management (DDM) plays a prominent role in supporting simulation entities as many as possible. In order to provide a flexible solution of region matching to different simulation scenarios, we propose a region matching approach for DDM, MGRID. MGRID can gather run-time information about regions, then evaluate the information by our region matching cost model and make adjustments for present situation accordingly. MGRID has been implemented in our HLA RTI system using C++ language, which follows IEEE Standard 1516. In addition, we have implemented region-based approach, hybrid-based approach and sort-based approach for comparison. In our experimental evaluations MGRID performed well in all test cases.
