Abstract: In order to meet the ever-growing need for wireless data and services, 5G cellular systems are advocating fundamental advances in both utilizing the radio access spectrum efficiently and providing efficient data and service delivery through new system architectures. New research pillars are set for 5G cellular systems spanning over the next 15 years. In particular, the objectives for 5G cellular systems are achieving the ultra high capacity (1000x capacity/km2), ultra high data rates (100x), always connected to best networks, high mobile cyber security, energy savings (90%) and enormous cost reduction, reduced latency (RAN latency less than 1ms), flexible network architectures (software defined networking) and connection of Billions of Things and People (7 billion people and 7 trillion things). In this talk these research pillars are explained in detail and open research challenges are presented.

Bio: I. F. AKYILDIZ received his BS, MS, and PhD degrees in Computer Engineering from the University of Erlangen-Nuernberg, Germany, in 1978, 1981 and 1984, respectively. Currently, he is the Ken Byers Chair Professor with the School of Electrical and Computer Engineering, Georgia Institute of Technology, Director of the Broadband Wireless Networking Laboratory and Chair of the Telecommunications Group. He is an Honorary Professor with School of Electrical Engineering at the Universitat Politecnica de Catalunya, and Director of N3Cat (NaNoNetworking Center in Catalunya) in Barcelona, Spain, since June 2008. Dr. Akyildiz is also the Finnish Distinguished Professor with Tampere University of Technology, Tampere, Finland since January 2013.

He is the Editor-in-Chief of Computer Networks (Elsevier) Journal since 2000, the founding Editor-in-Chiefs of the Ad Hoc Networks Journal (2003), Physical Communication (PHYCOM) Journal (2008), and Nano Communication Networks (NANOCOMNET) Journal (2010) all published by Elsevier.

Dr. Akyildiz is an IEEE FELLOW (1996) and an ACM FELLOW (1997). He received the 1997 IEEE Leonard G. Abraham Prize award and the 2003 Best Tutorial Paper Award and the Best Paper Awards at IEEE ICC, June 2009 and IEEE Globecom 2010 conferences (all IEEE Communications Society).

He received the “Don Federico Santa Maria Medal” for his services to the Universidad of Federico Santa Maria in Chile in 1986. He served as a National Lecturer for ACM from 1989 until 1998 and received the ACM Outstanding Distinguished Lecturer Award for 1994. Dr. Akyildiz received the 2002 IEEE Harry M. Goode Memorial award (IEEE Computer Society) and the 2003 ACM SIGMOBILE Outstanding Contribution Award for his “pioneering contributions in the area of mobility and resource management for wireless communication networks”.

Dr. Akyildiz received the 2004 Georgia Tech Faculty Research Author Award for his “outstanding record of publications of papers between 1999-2003″. He also received the 2005 Distinguished Faculty Achievement Award from School of ECE, Georgia Tech, and the Georgia Tech Outstanding Doctoral Thesis Advisor Award for his 20+ years service and dedication to Georgia Tech and producing outstanding PhD students. He also received the 2009 ECE Distinguished Mentor Award by the Georgia Tech School of Electrical and Computer Engineering Faculty Honors Committee.

Dr. Akyildiz received the 2010 IEEE Communications Society Ad Hoc and Sensor Networks Technical Committee (AHSN TC) Technical Recognition Award with the citation: “For pioneering contributions to wireless sensor networks and wireless mesh networks”, in December 2010. He received the 2011 IEEE Computer Society W. Wallace McDowell Award for pioneering contributions to wireless sensor network architectures and communication protocols and the 2011 TUBITAK (Turkish National Science Foundation) Exclusive Award for outstanding contributions to the advancement of scholarship/research at international level.

He is the author of two textbooks on “Wireless Sensor Networks” and on “Wireless Mesh Networks” published by John Wiley & Sons in 2010 and 2007, respectively. Due to Google scholar, his papers received over 70+K citations and his h-index is 90 as of April 2015.

His current research interests are in 5G Cellular Systems, Nanonetworks, Cognitive Radio Networks and Wireless Sensor Networks.
