Evaluating the Quality of Sensor Data

The Faculty of Informatics is pleased to announce a seminar given by Jörg Kaiser

DATE: Tuesday, September 16, 2014
PLACE: USI Lugano campus, room SI-003, Informatics building (Via G. Buffi 13)
TIME: 15:00

ABSTRACT:
One of the common characteristics of cooperative vehicles is the interaction with the physical world. Prerequisite for this interaction is the reliable perception of the environment by sensors. The work was motivated by the advantages of exploiting remote sensors that will extend the range and modalities of sensing and, in principle, will contribute to a better environment perception. Such a distributed sensor system puts new substantial challenges on the dynamic assessment of sensor data which is difficult to solve with traditional engineering approaches. This talk focuses on the assessment of continuous-valued sensor data and presents a failure abstraction and handling concept that encapsulates individual sensor failures and generates a quality measure for sensor data. It will address how individual characteristics of sensors and detection mechanisms can be modeled and how the assessment can be evaluated to a validity value as a measure for the confidence in sensor data. The approach allows assessing sensor data quality in a uniform way and provides the basis for a distributed mobile application in which new sensor sources can be discovered and exploited spontaneously.
Also a brief survey will be presented on how the scheme is exploited in scenarios of cooperating vehicles that are subject of the European KARYON (Kernel-Based ARchitecture for safetY-critical cONtrol) project.

BIO:
Jörg Kaiser is a Full Professor at the Faculty of Computer Science at the Otto-von-Guericke University of Magdeburg where he leads the Department for Embedded Systems and Operating Systems (EOS). Before he joined the University of Magdeburg in 2004, he was Professor of Computer Science at the Department of Computer Structures in Ulm since 1995 and worked with the German National Research Centre for Information Technology (GMD), St. Augustin since 1980. He received his "Diplom in Informatik" and his Ph.D. in Natural Sciences from Bonn University. His research work ranged in computer architecture, operating systems, distributed systems and middleware with emphasis on object-orientation, fault-tolerance, and real-time. His research areas now have a strong emphasis on large scale distributed systems supervising and controlling real-world applications like industrial plants, automotive and avionics systems, smart spaces or teams of robots.
