Cognitive radio developed from software defined radio has been considered as a key technology in future wireless communications, which fundamentally enhances the radio spectral efficiency. However, cognitive radio is not only a physical layer transmission technology, but also provides intellectual challenges to further transport packets from cognitive radios via cooperative networking to form cognitive radio networks. The final goal is to support the overall networking efficiency at given radio spectrum bandwidth for better user end-to-end QoS, as a new research challenge. We start from spectrum sensing to introduce innovative cognitive radio network (CRN) tomography and introduce facilitation of routing and control over CRN , which can be useful to 3GPP LTE -A.

Biography: 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 Director for the Graduate Institute of Communication Engineering, and Director for the Communication Research Center, National Taiwan University. Dr. Chen actively involves the technical organization of numerous leading IEEE conferences, including as the Technical Program Committee Chair of 1996 IEEE International Symposium on Personal Indoor Mobile Radio Communications, TPC co-chair for IEEE Globecom 2002, General Co-Chair for 2007 IEEE Mobile WiMAX Symposium in Orlando, 2009 IEEE Mobile WiMAX Symposium in Napa Valley, IEEE 2010 Spring Vehicular Technology Conference, and IEEE Workshop on Social Networks in 2010 and 2011. He has served editorship with many IEEE and international journals and served various positions in IEEE . Dr. Chen also actively participate various wireless international standards. He has authored and co-authored over 200 technical papers and 18 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 numerous awards and honors, including ISI Classical Citation Award and Best Paper Award from IEEE International Conference on Communications 2010. Dr. Chen’s research interests include wireless communications and networks, nano-communications, and network science.
