Abstract

LOG-a-TEC is a sensor network testbed for spectrum sensing and cognitive radio applications on embedded devices. It consists of 50 remotely-controlled VESNA nodes mounted on light poles. Nodes are equipped with ARM Cortex-M3 processors, local storage and reconfigurable radio transceivers for 868 MHz, 2.4 GHz and UHF TV bands. The course will begin with a description of the testbed infrastructure, capabilities of the radio hardware and the means of remote access. A Python interface to the testbed will be introduced that allows experiments to be written in a high-level programming language and controlled from the experimenter’s computer over the Internet. In the hands-on part of the course, participants will have the opportunity to write and run a simple experiment on the testbed from their own laptops over the web.
