Abstract:
This demonstration shows how VESNA wireless sensor nodes can be used for cognitive radio experiments involving wireless sensor networks. SNE-ISMTV is a radio frontend that has been developed for this purpose. Spectrum sensing capability in the TV white-spaces and 2.4 GHz ISM band is demonstrated by running receivers in a swept-tuned spectrum analyzer configuration and displaying measured spectrograms on a laptop PC. Analogue signal transmission simulating a wireless microphone is demonstrated by executing a direct digital synthesis algorithm on the sensor node microprocessor, transmitting the modulated signal using a narrow-band sub-1 GHz transceiver and monitoring the transmission using an USRP.
