Comparing high level architecture data distribution management specifications 1.3 and 1516

The high level architecture (HLA) is a standard for federations of distributed simulations that exchange run-time data. HLA’s data distribution management (DDM) services reduce data delivered to simulations based on their declarations of data produced and required. The HLA specifications, including DDM, were changed substantially from the Department of Defense 1.3 standard to the IEEE 1516 standard. The two DDM specifications’ (DDM 1.3 and DDM 1516) power to define intersimulation data flows are compared. A transformation from DDM 1.3 to DDM 1516 configurations and a mapping from DDM 1516 to DDM 1.3 configurations prove that the DDM specifications are equivalently powerful. 2001 Elsevier Science B.V.
