   Abstract: Although 71% of the Earth surface is covered by water, our knowledge about the oceans, rivers, and lakes is very limited. This talk gives an overall introduction to Ocean Big Data (OBD), Underwater Internet of Things (IoT), and underwater wireless communication technologies. In particular, the impacts of ocean big data and underwater IoT are discussed, and the challenges of underwater wireless communications are introduced. Several viable solutions to short- and medium-range underwater wireless communication systems include acoustic, magneto-inductive, and optical communications.  This talk will focus on recent progress in medium-range acoustic communications, providing tutorial understanding of physical-layer technologies (OFDM vs SCM and MIMO vs SISO) and network-layer approaches (Polling, CSMA, CDMA).  Current work at Missouri S&T on acoustic and MI communication means are also presented with results from practical field trials and ocean experiments.  


   Biography: Yahong Rosa Zheng received the B.S. degree from the University of Electronic Science and Technology of China, Chengdu, Sichuan Province, China, in 1987 and the M.S. degree from Tsinghua University, Beijing, China, in 1989. She received the Ph.D. degree from the Department of Systems and Computer Engineering, Carleton University, Ottawa, ONT, Canada, in 2002. From 1989 to 1996, she worked as engineer and technical staff at several companies, including Beijing Peony Electronics Group, Beijing China, Sagem Australasia, Sydney, Australia, and Polytronics, Markham, Canada.  From 2003 to 2005, she was an NSERC Postdoctoral Fellow with the University of Missouri-Columbia. Since fall 2005, he has been a faculty member with the Department of Electrical and Computer Engineering, Missouri University of Science and Technology, Rolla, MO, where she is now the Wilken’s Missouri Telecommunications Chair Professor. Her research interests include array signal processing, wireless communications, and wireless sensor networks. She has published more than 60 journal papers and more than 100 conference papers in these areas. She serves as Associate Editor for the IEEE Transactions on Vehicular Technology. Previously, she was an Associate Editor for the IEEE Transactions on Wireless Communications during 2006 --2008. She is the recipient of an NSF CAREER award in 2009. She has been an IEEE fellow and a Distinguished Lecturer of IEEE Vehicular Technology Society since 2015.
