Recently, the topic of cognitive radio has spurred a lot of interest within both academic and regulatory circles. Cognitive radios are envisioned to be capable of improving spectrum utilization as well as coexistence among wireless networks. However, a relatively low-cost research platform for implementation and demonstration of cognitive radio concepts in a typical wireless network scenario is still lacking. To address this issue, we have developed the CORAL platform which modifies the operation of low-cost wireless devices to collectively perform the essential tasks of a cognitive radio network such as radio environment awareness, white space selection, and co-channel interference avoidance. This demonstration will showcase the CORAL platform and its main cognitive radio features.
