Title: Distributed Average Consensus in the Presence of Network Uncertainty and Adversarial Conditions
Abstract: Rapid developments in digital system and networking technologies have led to the emergence of complex systems that need to be managed/controlled in a distributed manner over cyber infrastructures, such as wireless and wired broadband networks. The emergence of this type of network control systems, which range from smart grids and traffic networks of various sorts, to embedded electronic devices and robotic networks, has sparked huge interest in distributed control problems. In this tutorial, we present some recent progress in this area by focusing on distributed computation of the average (more generally, a weighted linear combination) of various parameters held at different components of a multi-component system, an operation that is key for several emerging control and coordination tasks. We discuss challenges pertaining to uncertainty about the network topology, adversarial network conditions (e.g., communication delays, packet drops, faulty/malicious nodes or links), convergence (in finite time or asymptotically), and privacy preservation. Several examples and applications are also presented.
Biography: Christoforos Hadjicostis is Professor of Electrical and Computer Engineering at the University of Cyprus. He received S.B. degrees in Electrical Engineering, Computer Science and Engineering, and Mathematics, the M.Eng. degree in Electrical Engineering and Computer Science, and the Ph.D. degree in Electrical Engineering and Computer Science, all from the Massachusetts Institute of Technology, Cambridge, MA. From 1999 to 2007, he was Assistant and then Associate Professor with the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. Since 2007, he has been with the University of Cyprus where he served as Chair of the Department of ECE and Dean of School of Engineering. His research focuses on fault diagnosis and tolerance in distributed dynamic systems; error control coding; monitoring, diagnosis and control of large-scale discrete event systems; and related applications. His work has received funding from the National Science Foundation (including an NSF Career Award), the Air Force Office of Scientific Research, the European Commission (including a Marie Curie International Reintegration Grant), Qatar Foundation, the Cyprus Research Promotion Foundation, and others.
