The network architecture for real-time distributed simulation was established during the Simulator Network (SIMNET) program in the 1980s and 1990s and evolved into the Distributed Interactive Simulation (DIS) and High Level Architecture (HLA) network protocols. Research was conducted to scale these networks up to large numbers of participants on local and wide area networks and this eventually became accepted practice in the training domain. As we extend the training network protocols to include tactical aircraft over a wireless network segment, the network architecture for this segment needs to be examined and compared with commercial best practices and emerging network research. We need to determine whether all of the network components are available, or alternatively need to be developed, to provide the scalability and service from the wireless network that we have leveraged from the proliferation of the terrestrial Internet Protocol (IP) networks. This paper examines alternative approaches to the wireless network routing and forwarding architecture for both tethered (using range support) and untethered (without range support) configurations, presents network modeling and simulation comparisons, examines security architecture implications, and makes recommendations for a viable wireless network architecture for Live, Virtual, and Constructive (LVC) training in the tactical airborne environment.
