A Software Radio-Empowered Sensor NetworkYafei Li, Zhitao He, Thiemo Voigt Swedish Institute of Computer Science{yafei, zhitao, thiemo}@sics.seSanna Leidelof ¨Saab SystemsAbstract— Low power wireless sensors are limited by current radio technologies to short communication range and lowthroughput. We envision that future radios with advanced software programmable encoding and modulation will bring sensornetworks unprecedented flexibility and performance. We havetaken a step towards realizing this vision by designing a softwarebased, narrow-band transceiver using the GNU Radio softwareand the Universal Software Radio Peripheral hardware. We haveverified the compatibility of our implementation with existingwireless sensor platforms. We demonstrate the flexibility of ourdesign with sensing applications running on a sensor networkcommunicating over hybrid radios.
