Network Science and Wireless Networks

When: Wednesday, June 19, 2013 at 4:00 pm
Where: DA 5th fl
Speaker: Dr. Kwang-Cheng Chen
Organization: National Taiwan University
Sponsor: CCNR


Although modern digital communication systems and networks are developed based on the theory of random processes and statistics, random graph has been widely introduced to study wireless networks of very random nature until last decade. Around the same time as the birth of network science, cognitive radio to more effectively utilize cherish spectrum was created, as the hottest subject in today’s wireless communications research. In this talk, explorations of applying random graphs and concepts of network science to cognitive radio networks, particular multi-hop ad hoc networks, will be introduced as the starting point. With more surprising correspondence between social networks and wireless communications, more clues to link network science and wireless networks together will be presented, to possibly indicate a new direction to develop technology beneficial to human beings’ everyday life.



Kwang-Cheng Chen received B.S. from the National Taiwan University in 1983, M.S. and Ph.D from the University of Maryland, College Park, United States, in 1987 and 1989, all in electrical engineering. From 1987 to 1998, Dr. Chen worked with SSE, COMSAT, IBM Thomas J. Watson Research Center, and National Tsing Hua University, in mobile communications and networks. Since 1998, Dr. Chen has been with National Taiwan University, Taipei, Taiwan, ROC, and is the Distinguished Professor and Deputy Dean, College of Electrical Engineering and Computer Science, National Taiwan University. Dr. He visited HP Labs. (Palo Alto, US) in 1997, TU Delft (Netherlands) in 1998, Aalborg University (Denmark) in 2008, and is visiting Massachusetts Institute of Technology in 2012-2013. Chen led the technical organization of more than 10 major IEEE conferences, as General Chair/Co-Chair or TPC Chair/Co-Chair. He has served editorship with many prestigious IEEE journals and served various positions in IEEE, with most recent appointment with the 2013 IEEE Fellow Committee and 2013-2014 Chair of IEEE ComSoc’s technical sub-committee on Social Networks. Dr. Chen’s technology has been adopted in the IEEE 802.11, IEEE 802.15, Bluetooth 2.0 and after, and 3GPP LTE-A (4G wireless communications). He has authored and co-authored over 200 IEEE/ACM papers and more than 20 granted US patents. He co-edits (with R. DeMarca) the book Mobile WiMAX published by Wiley 2008, and authors a book Principles of Communications published by River 2009, and co-author (with R.Prasad) another book Cognitive Radio Networks published by Wiley 2009. Dr. Chen is an IEEE Fellow and received a number of awards including 2011 IEEE Communications Society Wireless Communications Recognition Award and co-authoring 2010 IEEE ICC Best Paper and IEEE GLOBECOM GOLD Best Paper. Dr. Chen’s research interests include wireless communications and network science.
