Abstract
Software-defined networking (SDN), wireless virtualization, and information-centric networking (ICN) are promising technologies in next generation mobile networks. With SDN and wireless virtualization, the overall expenses of mobile cellular network deployment and operation can be significantly reduced by abstracting and sharing infrastructure and radio spectrum resources, which can accelerate the evolution of networks and further catalyze fundamental changes in the mobile ecosystem. Meanwhile, in-network caching, one of the key features of the ICN, can efficiently reduce the duplicate content transmission in networks. On the other hand, SDN in conjunction with the in-network caching shows great potential in future mobile networks; thus joint optimization of network and cache in 5G networks is necessary. In this talk, we will give a brief introduction to those new characters in 5G mobile networks and present some recent works regarding wireless virtualization, dynamic caching, and traffic control in SDN-enabled mobile networks. Further challenges and future works will also be discussed.

Speaker’s Bio
Chengchao Liang is currently a Ph.D. candidate under the supervision of Prof. Richard Yu in the Department of Systems and Computer Engineering at Carleton University, Ottawa, Canada. He received the B.Eng. in Communication Engineering and M.Eng. in Communication and Information Systems, both from Chongqing University of Posts and Telecommunications, China, in 2010 and 2013, respectively. From 2011 to 2012, he was a visiting scholar at Mobile Telecommunications Research Lab, Inha University, South Korea. His research interests include SDN, network virtualization, resource allocation and applications of convex optimization in mobile networks. He has published several papers in reputable journals/conferences in these areas. Particularly, his paper on wireless network virtualization has been cited for more than 110 times since it was published in 2015. His paper on information-centric NFV over 5G was ranked #1 among the most popular papers in IEEE Network in Dec. 2015. He serves as reviewer and TPC for several journals and conferences, including IEEE Transactions on Networking, Communications, Wireless Communications, Vehicular Technology, IEEE Journal on Selected Areas in Communications, IEEE GLOBECOM, IEEE VTC, etc.
