Alumni Vortrag: “Efficient Data Stream Processing in the Internet of Things”

Auftakt der SWCA Vortragsreihe – Den Start macht unser Vereinsmitglied Jonas Traub am 7. Dezember 2020 um 20Uhr mit einem Vortrag aus seinem Fachgebiet.

Titel: Efficient Data Stream Processing in the Internet of Things

Abstract: The Internet of Things (IoT) consists of billions of devices which form a cloud of network-connected sensor nodes. These sensor nodes supply a vast number of data streams with massive amounts of sensor data. Real-time sensor data enables diverse applications including traffic-aware navigation, machine monitoring, and home automation. In this talk, we will dive into recent research which optimizes real-time data gathering and data analysis in the IoT. The talk will provide an overview of available techniques which can be deployed on sensor nodes, intermediate network nodes, and central analysis systems. We will look into the state-of-the-art in practice and research and make you aware of important tradeoffs in real-time IoT data analysis.

CV: Jonas Traub is a postdoctoral researcher at the Database Systems and Information Management group at TU Berlin. His main research interests include stream processing, sensor data analysis, and data acquisition techniques. In his PhD, he studied efficient data gathering, processing, and transmission in the IoT. His research shows that one can save up to 87% in sensor reads and data transfers by applying smart data reduction techniques on sensor nodes. He further introduced a demand-based control layer which optimizes the data acquisition from thousands of sensors. With his Scotty-framework, he contributed a general aggregation technique for streaming systems which outperforms alternative solutions by an order of magnitude in throughput. His work received a Best Paper Award at the 22nd International Conference on Extending Database Technology (EDBT). Prior to his work at TU Berlin, he studied at KTH Stockholm and DHBW Stuttgart and worked several years at IBM in Germany and the USA. Jonas is an alumnus of Software Campus where he worked with SAP as industry partner.
