Traffic predictions for tactical wideband communications

The joint tactical radio system (JTRS) wideband networking waveform (WNW) will be a fundamental new capability for a variety of tactical users. In future U.S. marine corps (USMC) operations, the WNW will be the backbone network for the tactical users with other waveforms used in the lower tiers. Performance of the WNW will need to be stringent to ensure connectivity with adequate quality of service. A study has been conducted to determine the performance of this system in USMC scenarios. This work has included an assessment of traffic loads on the network and modeling and simulation to determine the performance of the WNW in various USMC scenarios. This paper focuses on the methodology for traffic prediction which is a key need for DoD to conduct rigorous networking engineering.
