A joint project between the California and New Mexico branches of Sandia National Laboratories has demonstrated the formation of joint real-time federations of both distributed simulations and distributed simulation users under a common scenario. Two software integration frameworks were used to achieve the real-time federations. The IDSim framework, developed by Georgia Tech University and Sandia National Laboratories, was used to create the real-time federation of distributed simulations, in this case the BioDAC WMD simulation and the N-ABLE™ agent-based microeconomic simulation (more properly, because of the impact of hurricanes Katrina and Rita, an N-ABLE™ emulator). The GroupMeld™ multimedia synchronous collaboration framework, developed by Sandia, was used to create the real-time federation of simulation users and simulation analysis communities. The common scenario was the release of smallpox over San Diego, California, and the operating hypothesis was that the economy itself dampens the spread of a pathogen. In addition, a small pilot experiment using the joint federations allowed a greater range of crisis management options to be performed and evaluated than would have been possible without the use of the integration frameworks. © 2007 IEEE.

The one-year Software Architecture LDRD (No.79819) was a cross-site effort between Sandia California and Sandia New Mexico. The purpose of this research was to further develop and demonstrate integrating software architecture frameworks for distributed simulation and distributed collaboration in the homeland security domain. The integrated frameworks were initially developed through the Weapons of Mass Destruction Decision Analysis Center (WMD-DAC), sited at SNL/CA, and the National Infrastructure Simulation & Analysis Center (NISAC), sited at SNL/NM. The primary deliverable was a demonstration of both a federation of distributed simulations and a federation of distributed collaborative simulation analysis communities in the context of the same integrated scenario, which was the release of smallpox in San Diego, California. To our knowledge this was the first time such a combination of federations under a single scenario has ever been demonstrated. A secondary deliverable was the creation of the standalone GroupMeld{trademark} collaboration client, which uses the GroupMeld{trademark} synchronous collaboration framework. In addition, a small pilot experiment that used both integrating frameworks allowed a greater range of crisis management options to be performed and evaluated than would have been possible without the use of the frameworks.
