Recent proliferation of wireless technologies and choices available to user applications have triggered a tremendous wireless demand, and the wireless nodes are expected to dominate the Internet soon. Accommodating this exploding wireless demand with cellular capacity does not seem possible in the long run. As the RF spectrum is getting scarcer and saturated by recent innovations in attaining high spectral efficiency gains, we urgently need innovations that will enable leveraging of new wireless spectrums and substrates in order to respond to the exploding mobile wireless traffic demand. Further, the capacity gap between radio frequency (RF) wireless and optical fiber backbone speeds will remain huge because of the limited availability of RF spectrum. This gap in the “last mile” of the Internet is getting more troublesome as Internet-of-Things (IoT) is becoming a reality and more things around us need wireless connectivity. Enabling optical spectrum in wireless communications is the needed revolution for high-speed mobile networks of the future.

In this talk, I will present our work on exploring the potential for free-space-optics (FSO), a.k.a. optical wireless, in the context of high-speed mobile ad-hoc and opportunistic networking. We introduce basic multi-element building blocks and prototypes for multi-hop FSO-based mobile networking. 3-D spherical structures covered with inexpensive FSO transceivers (e.g., LED and photo-detector pairs) solve issues relevant to mobility and line-of-sight (LOS) management via availability of several transceivers per node. Such structures facilitate electronic LOS tracking (i.e., “electronic steering”) methods instead of traditional mechanical steering techniques used in FSO communications. By abstracting FSO directionality and LOS characteristics, our work also explores issues relating to routing and indoor localization, and develops layer 3 protocols. FSO has been used at high-altitude communications, and this research enables FSO communications at lower-altitudes and in ad-hoc settings with redundancy of cheap optoelectronic components. I will also present our recent efforts on using these multi-element modules for lighting and their potential role in integration of illumination and communication functions.


Murat Yuksel is an Associate Professor at the ECE Department of the University of Central Florida (UCF). Prior to UCF, he was an associate professor at the CSE Department of University of Nevada - Reno (UNR). He was with the ECSE Department of Rensselaer Polytechnic Institute (RPI), Troy, NY as a Postdoctoral Associate and a member of Adjunct Faculty until 2006. He received M.S. and Ph.D. degrees in computer science from RPI in 1999 and 2002 respectively, and a B.S. degree in computer engineering from Ege University, Izmir, Turkey in 1996. He worked as a software engineer at Pepperdata, Sunnyvale, CA and a visiting researcher at AT&T Labs and Los Alamos National Lab. His research interests are in the area of networked, wireless, and computer systems with a recent focus on optical wireless, spectrum sharing, device-to-device systems, cloud networking, network architectures and economics, and network management and simulation. He has been on the editorial board of Computer Networks, and published more than 100 papers at peer-reviewed journals and conferences and is a recipient of the IEEE LANMAN 2008 Best Paper Award. He is a senior member of IEEE, senior and life member of ACM, and was a member of Sigma Xi and ASEE.
