Title: Composition Challenges in Large-scale Cyber-physical Systems
Cyber-physical computing envisions a next generation of large distributed systems that are open, highly interconnected, and deeply embedded in the physical world. Such systems have become a research priority in networking and information technology, as recommended by PCAST, the nation's Presidential Council of Advisors on Science and Technology. Research challenges in cyber-physical computing arise from the multiple modalities of system interactions with the physical world, including temporal, functional, and data interactions, as well as from increased system scale. New composition challenges arise as systems grow in size and complexity, making it particularly hard to reason about their overall behavior. This talk discusses the top emerging challenges in cyber-physical systems, with emphasis on those that arise by virtue of scale. Recent research directions and initial solutions are presented to address problems of increasing interest in this realm.
Tarek Abdelzaher received his B.Sc. and M.Sc. degrees in Electrical and Computer Engineering from Ain Shams University, Cairo, Egypt, in 1990 and 1994 respectively. He received his Ph.D. from the University of Michigan in 1999 on Quality of Service Adaptation in Real-Time Systems. He has been an Assistant Professor at the University of Virginia, where he founded the Software Predictability Group until 2005. He is currently an Associate Professor at the Department of Computer Science, the University of Illinois at Urbana Champaign. He has authored/coauthored more than 150 refereed publications in real-time computing, distributed systems, sensor networks, and control. He is Editor-in-Chief of the Journal of Real-Time Systems, an Associate Editor of the IEEE Transactions on Mobile Computing, IEEE Transactions on Parallel and Distributed Systems, the ACM Transaction on Sensor Networks, and the Ad Hoc Networks Journal. He was Program Chair of RTAS 2004, RTSS 2006, IPSN 2010 and ICDCS 2010, as well as General Chair of RTAS 2005, IPSN 2007, RTSS 2007, DCoSS 2008, and Sensys 2008. Abdelzaher's research interests lie broadly in understanding and controlling performance and temporal properties of networked embedded and software systems in the face of increasing complexity, distribution, and degree of embedding in an external physical environment. Tarek Abdelzaher is a member of IEEE and ACM.
