Abstract
High Level Architecture is a common framework for reuse and interoperation of simulation. Run-time Infrastructure which is the fundamental component of HLA provides several services for simulators’ interaction. In High Level Architecture, the purpose of Data Distribution Management is to reduce transmission and irrelevant data among simulators by comparing their interesting regions. In this paper, we propose a matching method for Data Distribution Management to deal with simulations which can cover a large range of size of regions. In our approach, these regions are mapped onto an adaptive grid and the size of grid cells can be changed dynamically based on our matching cost model. Experimental evaluations show that our approach is more efficient than approaches with static grid cell size.
