Abstract :
In our demonstration, we show how cognitive radios can be organized to form a cooperative ad-hoc cognitive radio network that utilizes the available spectrum opportunistically and efficiently through channel allocation while at the same time avoiding causing interference to primary users as they become active. Our cognitive radios are Software Defined Radios consisting of a Linux laptop and a Universal Software Radio Peripheral integrated with our extended implementation of the GNU Radio software package and our Localized island Genetic Algorithm implementation for the channel allocation.
