Physical Optics Corporation — Department of Defense SBIR Phase I: N142-112

Description

To address the Navy need to provide existing and emerging single-transceiver radios with the capability to autonomously and dynamically access and manage spectrum, Physical Optics Corporation (POC) proposes to develop a new Single Transceiver Radio Efficient Dynamic Spectrum Access for Mobile Ad-Hoc Networks (STREAM) system. This system will allow single-transceiver radios in a platoon-sized mobile ad-hoc network (MANET) of 20 or more nodes to autonomously and dynamically access and manage the spectrum to increase spectral efficiency and network throughput. The proposed system will leverage in-house self-interference reduction and spectrum sensing techniques, together with state-of-the-art methods for spectrum management and mobility, optimized to maximize network throughput, while minimizing latency and transceiver power usage. As a result, the STREAM system will deliver frequency selection and transitions in under 500 milliseconds while maintaining high network throughput on a MANET of 20 or more single-transceiver nodes, which supports the envisioned network scenario of a platoon-size dismounted patrol in an urban environment. POC plans to develop in Phase I a technical description of the STREAM system and demonstrate the feasibility via simulation and measurements with an in-house software-defined radio testbed. In Phase II, POC will develop prototype nodes to assess the STREAM system.
