s Army tactical networks become more and more complex, the tools used to analyze these networks must also evolve. In many cases the modeling and simulation (M&S) capabilities developed by various


Army organizations and contractors over the past 10-15 years do not have the technical capabilities to meet the Army’s com- plex needs today, such as detailed routing and latency analysis. As the Army moves to a more complex M&S environment, the acquisition and science and technology communities must work toward a defined end state—that is, a common, robust envi- ronment for our M&S capabilities. By doing so, we can avoid stovepiped processes, unneeded and repetitive analyses, and potentially duplicative spending by project managers (PMs).


Te complexity of the Army tactical network is causing inte- gration issues with new technologies. Tat is driving the Army toward a system-of-systems (SoS) engineering and integration approach in which analysis needs to be conducted earlier and at larger scales beyond the component level. Currently, new technologies aren’t tested on an SoS network until they are at technical readiness level (TRL) 5 – 6. Tis often makes it nec- essary to rework these technologies or to rework the network for them to add value. Terefore, we need to take a conscious look as an Army at cost, in terms of reining in current spend- ing and coordinating capabilities across the Army acquisition community. When possible, if technologies can be integrated at

an earlier level of development, TRL 3 or 4, that would enable course corrections to happen earlier in the development process, and at less cost.


Te U.S. Army Research, Development and Engineering Com- mand’s Communications-Electronics Research, Development and Engineering Center (CERDEC) is using the expertise and infrastructure of its Space and Terrestrial Communications Directorate (S&TCD) to build a holistic, tactical M&S envi- ronment that will provide significant long-term cost savings to the Army.


Working with Program Executive Office Command, Control and Communications – Tactical (PEO C3T) and leveraging capabilities developed by the U.S. Army Research Laboratory Mobile Network Modeling Institute (ARL MNMI), CERDEC has begun development of the Modeling, Emulation, Simulation Tool for Analysis (MODESTA). Tis tool provides a large-scale, tactical network analysis environment with a centralized frame- work so engineers and analysts can conduct realistic, operational scenarios with emulated and simulated systems—all while accessing centralized data models and data collection, reduction and analysis tools.


Working under the MODESTA framework will create efficien- cies in licensing, waveform development, and maintenance and
