PIC: Cognitive radio algorithms and software for intermittent bandwidth limited RF networks

OVERALL OBJECTIVES: 1) Simulate intermittent bandwidth-limited RF broadband networks, data and interferences/noise using NS-3/NetSim and GNU Radio/RedhawkSDR, 2) Explore different algorithms (machine learning and traditional) to establish/maintain/re-establish connectivity in cognitive radio (CR) networks (CRN): a) mitigate effects of delays, loss of connectivity, denial of service and interferences, b) spectrum sensing, frequency management/spectrum scheduling, self-organization and adaptive routing, and 3) Develop a flexible framework (testbed) based on NS-3/NetSim and GNU Radio/RedhawkSDR (and their CR extensions) for simulating CRNs in a scalable manner and for evaluating CR algorithms using a common interface.
