Boris Koldehofe: "Adaptive distributed event processing in a complex world"

Gebäude 350, Raum U014

An increasing number of applications, for instance business applications like logistic chains, integrate data from a large number of data sources such as sensors and RFIDs.  This trend is amplified by the fact that in the future the number of sensor devices is expected to grow to possibly billions or trillions of devices. In this context event-based communication plays an important role to i) integrate and process this information effectively, ii) allow for simple reconfiguration of applications.  This talk highlights principles, challenges as well as solutions in realizing event-processing systems to perform highly scalable and adapt to heterogeneous networks and devices. In particular, we focus on two main classes of event-based systems, publish/subscribe and complex event processing. The first allows asynchronous interactions between senders and the receivers, while the latter also supports the detection of complex situations by performing correlations between events.


Boris Koldehofe graduated in 1999 at the Universität des Saarlandes, Germany, and obtained in 2005 a Ph.D. at Chalmers University of Technology. Thereafter he stayed for one year as PostDoc at the EPFL in Lausanne and joint in 2006 the Institute of Parallel and Distributed Systems (IPVS), Universität Stuttgart.  There he works as senior researcher and lecturer and is responsible for the project division Adaptive Communication Systems. His current research is centered on distributed systems and computer communications. In particular, his research interest includes services and applications for the Next Generation Internet, Peer-to-Peer Systems, Distributed Event-Based System, and Global Sensor Networks.
