Bachelor/Master Thesis Student ML based Classification of States in LPWAN Current Consumption Curves

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros. 

The department of »Self-Powered Radio Systems« in Nürnberg, Germany is focused on efficient systems and protocols for wireless data transmission and energy harvesting. One priority is the area of Internet of Things (IoT) and Industrial Internet of Things (IIoT), which led to the development and ongoing improvements of Mioty, a new low-power wide-area network (LPWAN) technology. Mioty, an ETSI standardised system, is analysed, among other features, with respect to energy efficiency, and compared to other LPWAN technologies, e.g. NB-IoT (3GPP).

 

To predict the energy consumption of different LPWAN systems, i.e. Lora, Mioty, NB-IoT and Sigfox, a Python based analysis framework has been developed. In an automated test setup, current consumption of different communication stages, e.g. transmission, reception, sleep, for all LPWAN systems are measured. To classify the different communication stages in the measured time series, machine learning algorithms shall be applied.
