ABSTRACT:
Abstract: The last decade saw the rise of cyber-physical systems to prominence. We started witnessing the application of networked systems in many areas, e.g., smart grids, unmanned vehicles formation control, and wireless control in process industry. Such a widespread use of these systems while addressed many problems, caused many concerns in terms of reliability and security. This can be explained by the following example. By distributing the computation across a network we reduce the computational load on a single node and ensure reliability and availability by removing single points of failure in the system. However, the same distribution, for example, provides a malicious agent with many points of entry into the system. These points of entries may be used by such an agent to eavesdrop on the data or corrupt the communicated or measured information between subsystems in the network, or even sabotage the sub-systems in the network. In addition, by introducing more components to the system we increase the possibility of hardware failure and having faulty measurements caused by such hardware failures. In this talk we consider the following problem: What are the possible strategies to ameliorate the effect of such faults in a network of interconnected systems?
BIO:
Iman Shames is a Postdoctoral Researcher at the ACCESS Linnaeus Centre, KTH - Royal Institute of Technology, Stockholm, Sweden. Before joining KTH, he worked as a researcher in NICTA Canberra lab in 2010. He received his B.S. degree in Electrical Engineering from Shiraz University, Iran in 2006, and the Ph.D. degree in engineering and computer science at the Australian National University, Canberra, Australia in 2010. He has been a visiting researcher at the Delft Technical University (2011), Technical University of Munich (2011), the University of Sydney (2011), the Royal Institute of Technology (KTH) (2010 and 2009), the University of Tokyo (2008), and at the University of Newcastle (2010 and 2005). His current research interests include networked (bio)cyber-physical systems, multi-agent systems, sensor networks, distributed fault detection and isolation, distributed optimisation, and compressive sensing and signal reconstruction.
