Wideband Networking Waveform (WNW) Enhancement

The Wideband Networking Waveform (WNW) utilized by the Joint Tactical Radio System (JTRS) uses an adaptive networking architecture that optimizes network routing performance and overall network stability for various tactical applications. However, maintaining the desired performance to meet the demands of heterogeneous applications operating over a wide variety of deployment scenarios, with dynamically varying density and mobility patterns continues to be a challenge. The overall objective of the SBIR proposal, over the next three phases, is to deliver a set of cross-layer based enhancements to the Wideband Networking Waveform (WNW) to overcome the performance issues under dense and unstable network conditions and improve its performance in diverse set of on-the-move operational scenarios. The proposed enhancements focus on integrated adaptive transmit power control, adaptive routing update frequency control and adaptive control of degree of node connectivity via routing layer filters. In Phase 1, we will conduct design trade studies of the preceding WNW enhancements and perform a proof-of-concept demonstration for the most promising approach using Scalable JMEE, a real-time WNW emulation environment. The study will isolate the set of adaptive & scalable enhancements needed to the baseline WNW that can be smoothly transitioned to the JTRS program.
