Project Summary

This project focuses on the development of ROAR: A Real-time Opportunistic spectrum Access in cognitive Radio networks testbed. This project will setup a cloud-based cognitive network for real-time opportunistic spectrum access across diverse RF bands (e.g., 10 Hz – 13 GHz) including cellular, IEEE 802.11 a/b/g/n, IEEE 802.15.4, DSRC/WAVE and Bluetooth networks. This project impacts the implementation, evaluation and development of future wireless systems. This project also enables experimental investigations in a number of other research projects, including secure dynamic spectrum access design, cognitive radio enabled opportunistic spectrum access in highly mobile vehicular networks, primary user security emulation, energy management techniques for mobile devices, cross-layer based protocol design, security for cyber-physical system design, interference mitigation techniques and wireless resource management schemes.

The information gained from ROAR will provide a platform to assess maturity of the technology and identify areas that need further research for real-time opportunistic dynamic spectrum access in a heterogeneous cognitive network environment, and will support enhancement of our national wireless infrastructure and capacity. ROAR will have a broad societal impact as wireless networks touch every aspect of our society. Project-based learning will be incorporated in related undergraduate and graduate courses to integrate research and education.
