Andreas Springer | Johannes Kepler University Linz (original) (raw)

Andreas Springer received the Dipl.-Ing. degree in Electrical Engineering from the Technical University of Vienna, Austria, in 1991, the Dr. techn. (Ph.D) degree and the Univ.-Doz. (Habilitation) degree both from the Johannes Kepler University Linz (JKU), Austria, in 1996 and 2001, respectively. From 1991 to 1996 he was with the Microelectronics Institute at JKU. In 1997, he joined the Institute for Communications and Information Engineering at the same university, where he became a full professor in 2005. Since July 2002 he is also head of the Institute for Communications Engineering and RF-Systems (formerly Institute for Communications and Information Engineering) at JKU. In the Austrian Center of Competence in Mechatronics (ACCM) he serves as the coordinator for the research area “Wireless Systems”. Since 2017 he is co-leader of the “Christian Doppler Lab for Digitally Assisted RF Transceivers for Future Mobile Communications”.
He is member of the editorial board of the International Journal of Electronics and Communications, and he serves as reviewer for a number of international journals and conferences. He has been engaged in research work on GaAs integrated millimeter-wave TED’s, MMIC’s and millimeter-wave sensor systems. His current research interests are focused on wireless communication systems, architectures and algorithms for multi-band/multi-mode transceivers, wireless sensor networks, millimeter wave communications and recently molecular communications. In these fields, he has published more than 250 papers in journals and at international conferences, one book, and two book chapters. In 2006 he was co-recipient of the science prize of the German Aerospace Center (DLR)
Dr. Springer is a member of the IEEE Microwave Theory and Techniques, the Communications, and the Vehicular Technology societies, OVE, and VDI. From 2002 to 2012 he served as Chair of the IEEE Austrian Joint COM/MTT Chapter.

The cabling of sensors represent a considerable effort and potential source of error, which can be avoided by using wireless sensor nodes. These wireless sensor nodes form a wireless sensor network (WSN) to efficiently transmit data to the destination. For the acceptance of WSNs in industry, it is important to build up networks with high trustworthiness. The trustworthiness of the WSN depends not only on a secure wireless communication but also on the ability to detect modifications at the wireless sensor nodes itself. This paper presents the enhancement of the WSN’s trustworthiness using an optical localization system. It can be used for the preparation phase of the WSN and also during operation to track the positions of the wireless sensor nodes and detect spatial modification. The location information of the sensor nodes can also be used to rate their trustworthiness.

Moreover, we show the equivalence of the four approaches. All methods apply a Gaussian approximation, but at different stages, e.g. Gaussian approximation on the LMMSE filter output. Each approach offers different strategies for reducing the computational complexity, where the factor graph approach is the most promising solution.

The complexity of these devices as well as the number of connected devices to networks increase steadily. The high intricacy of the overall system makes it error-prone and vulnerable to attacks and leads to the need to test individual parts or even the whole system. Therefore, this paper presents the concept of a flexible and distributed testbed to evaluate correct behavior in various operation or attack scenarios. It is based on the Robot Operating System (ROS) as communication framework to ensure modularity and expandability. The testbed integrates RF-jamming and measurement devices to evaluate remote attack scenarios and interference issues. An energy harvesting emulation cell is used to evaluate different real-world energy harvesting scenarios. A climatic test chamber allows to investigate the influence of temperature and humidity conditions on the system-under-test. As a testbed application scenario, the automated evaluation of an energy harvesting wireless sensor network designed to instrument automotive engine test benches is presented.
