Exponential growth of mobile data traffic due to extensive uses of smartphones and tablets in various applications has created tremendous traffic burden on existing telecommunications infrastructure. Although significant efforts have already been made on spectrum efficiency by developing various innovative transmission technologies, we cannot jump over the hurdle imposed by the physical transmission limit (Shannon said so). Besides, efficient one-hop physical transmission technologies will not work well without effective network support for end-to-end user services. Cognitive radio technology was envisioned to unleash under-utilized licensed spectra and opportunistically utilize them to support communications services without affecting the incumbent spectrum users. Unfortunately, most research focuses on either cognitive radio design or spectrum sensing mostly for one-hop communications, which cannot handle end-to-end services effectively. LTE standardization has also looked into potential use of unlicensed bands (e.g., mmWave) to relieve the traffic burden. In this talk, the speaker will discuss design challenges in spectrum harvesting networks and then present a novel network solution to effective spectrum harvesting and optimization. This design not only enables network operators to tap unused (licensed/unlicensed) bands opportunistically and effectively, but also offers other optional strategies for significant network performance gain.


Yuguang "Michael" Fang (F'08) received an MS degree from Qufu Normal University, Shandong, China in 1987, a Ph.D degree from Case Western Reserve University in 1994 and a Ph.D. degree from Boston University in 1997. He was an assistant professor in Department of Electrical and Computer Engineering at New Jersey Institute of Technology from 1998 to 2000. He then joined the Department of Electrical and Computer Engineering at University of Florida in 2000 and has been a full professor since 2005. He held a University of Florida Research Foundation (UFRF) Professorship from 2006 to 2009, a Changjiang Scholar Chair Professorship with Xidian University, China, from 2008 to 2011, and a Guest Chair Professorship with Tsinghua University, China, from 2009 to 2012.


Dr. Fang received the US National Science Foundation Career Award in 2001 and the Office of Naval Research Young Investigator Award in 2002, 2015 IEEE Communications Society CISTC Technical Recognition Award, 2014 IEEE Communications Society WTC Recognition Award, and the Best Paper Award from IEEE ICNP (2006). He has also received a 2010-2011 UF Doctoral Dissertation Advisor/Mentoring Award, 2011 Florida Blue Key/UF Homecoming Distinguished Faculty Award, and the 2009 UF College of Engineering Faculty Mentoring Award. He is the Editor-in-Chief of IEEE Transactions on Vehicular Technology, was the Editor-in-Chief of IEEE Wireless Communications (2009-2012), and serves/served on several editorial boards of journals including IEEE Transactions on Mobile Computing (2003-2008, 2011-present), IEEE Transactions on Communications (2000-2011), and IEEE Transactions on Wireless Communications (2002-2009). He has been actively participating in conference organizations such as serving as the Technical Program Co-Chair for IEEE INOFOCOM’2014 and the Technical Program Vice-Chair for IEEE INFOCOM'2005. He is a fellow of the IEEE.
