Cognitive Radio Utilization and Integration of Spectrum Emission

To address the U.S. Navy need for a wireless network spectrum management system for the common unlicensed frequency bands and that can shift to other frequency bands, Physical Optics Corporation (POC) proposes to develop a new Cognitive Radio Utilization and Integration of Spectrum Emission (CRUISE) system based on software defined radio transceivers and novel cognitive radio techniques. In particular POC will extend the present media access control elements of the 802.11 protocols to address issues arising from hidden and exposed nodes, particularly within directional systems. POC will develop a system for flexible frequency and modulation control. This will reduce bandwidth saturation, automatically reroute network traffic around physical obstacles, ensure data packet fidelity, adjust transmission power to eliminate interference with neighboring transceivers, and extend the range of 802.11 wireless networks by using each network node as a repeater to relay messages to remote nodes. In Phase I POC will demonstrate the feasibility of CRUISE network technology by building a technology demonstration unit to validate all key fundamental principles. In Phase II POC will develop several advanced CRUISE prototypes, which will prove all aspects of its advanced, adaptable, and revolutionary network architecture.
