Abstract: It has long been a significant but difficult problem to identify propagation sources based on limited knowledge of network structures and the varying states of network nodes. Real cases of identifying propagation sources include finding the spreader of malware in computer networks, locating the sources of rumors in online social networks and finding origins of a rolling blackout in smart grids. This talk reviews the state-of-the art in source identification techniques, and discusses the pros and cons of current methods in this field. Furthermore, in order to gain a quantitative understanding of current methods, we provide a series of experiments and comparisons based on various environment settings. Especially, our observation reveals considerable differences in performance by employing different network topologies, various propagation schemes and diverse propagation probabilities. We therefore reach a number of points for future work and list some open issues of current methods. Solutions to these open issues are of great academic and practical significance. This talk will mainly be based on the following recently accepted survey paper: "Jiaojiao Jiang, Sheng Wen, Shui Yu, Yang Xiang, Wanlei Zhou, and Ekram Hossain, "Identifying Propagation Sources in Networks: State-of-the-Art and Comparative Studies", Accepted by IEEE Communications Surveys and Tutorials, accepted: 17/9/2014".
Bio: Professor Wanlei Zhou received the B.Eng and M.Eng degrees from Harbin Institute of Technology, Harbin, China in 1982 and 1984, respectively, and the PhD degree from The Australian National University, Canberra, Australia, in 1991, all in Computer Science and Engineering. He also received a DSc degree (a higher Doctorate degree) from Deakin University in 2002. He is currently the Alfred Deakin Professor (the highest honour the University can bestow on a member of academic staff) and Chair Professor in Information Technology, School of Information Technology, Deakin University. Professor Zhou has been the Head of School of Information Technology twice (Jan 2002-Apr 2006 and Jan 2009-Jan 2015) and Associate Dean of Faculty of Science and Technology in Deakin University (May 2006-Dec 2008). Before joining Deakin University, Professor Zhou served as a lecturer in University of Electronic Science and Technology of China, a system programmer in HP at Massachusetts, USA; a lecturer in Monash University, Melbourne, Australia; and a lecturer in National University of Singapore, Singapore. His research interests include distributed systems, network security, bioinformatics, and e-learning. Professor Zhou has published more than 300 papers in refereed international journals and refereed international conferences proceedings, including more than 30 articles in IEEE journal in the last 5 years. He has also chaired many international conferences. Prof Zhou is a Senior Member of the IEEE.
