Single Transceiver Radio Efficient Dynamic Spectrum Access for Mobile Ad-Hoc Networks Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-112 Topic Title: Single Transceiver Radio Efficient Dynamic Spectrum Access for Mobile Ad-Hoc Networks Proposal No.: N142-112-0292 Firm: Physical Optics Corporation Applied Technologies Division 1845 West 205th Street Torrance, California 90501 Contact: John Matthews Phone: (310) 320-3088 Web Site: www.poc.com Abstract: 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. Benefits: The versatile architecture of the STREAM approach is readily adaptable to a wide variety of surveillance and reconnaissance applications, giving it broad commercial potential. In addition to the military communications market, we identified large commercial potential of the STREAM technology in a wide variety of governmental and commercial markets. For civilian applications, STREAM provides enabling technology for future cognitive radio networks. Femto-cells in cellular networks can benefit from the STREAM efficient, high-throughput DSA capability to maintain high-bandwidth data transfer in spectrally-congested urban environments. Local law enforcement, first responders, and rescue units can benefit from integration of the STREAM DSA capability into multi-band radios, in order to ensure reliable communications between team members in emergency situations.
