Recent advancements in software defined radio (SDR) technologies have increased the likelihood that most radio infrastructures will transition away from legacy hardware architectures. SDR technologies offer simple flexibility combined with efficiencies in business models, making them the optimum solution for most radio requirements. As SDR proliferates, it(More)
The cognitive radio is an emerging technology that holds great promise due to its adaptive nature and ability to exploit the advantages inherent to software defined radios (SDR). The cognitive radio's potential to address spectrum access challenges resulting from an exponential increase in the number of network devices will make it a leading technology of(More)
Even though security research in cognitive radio offers specific countermeasures to address known threats, there are a number of unknown conditions or influences that will shape its eventual realization once it reaches capability maturity. To attempt to secure against such unknowns, this chapter describes a risk engine that can incorporate a risk assessment(More)
