Following cloud computing, which is about IT resource (such as CPU, memory, storage) virtualization, there are many research activities on the virtualization of another resource in the Internet, i.e., networks. Starting with an overview of wired network virtualization in terms of its major research topics and challenges, this talk stays focused on the discussion of the unique features of wireless network virtualization. Based on a real-life scenario of virtual mobile network operators this talk will mainly present an elastic resource allocation algorithm that conducts not only network virtualization (i.e., slicing and isolation) but also efficient resource allocation among multiple user application flows. The resource allocation is based on the next-generation wireless communication technology, i.e., OFDMA (Orthogonal Frequency Division Multiple Access). The corresponding performance evaluation results are also going to be presented. The talk will conclude by looking into the future research topics and directions in this young and exciting research field of wireless network virtualization.
Short bio: Kun Yang (杨鲲) obtained his PhD from the Department of Electronic & Electrical Engineering of University College London (UCL), UK, and his MSc and BSc degrees were both from Jilin University. He is currently a Chair Professor and the Head of Network Convergence Laboratory (NCL) in the School of Computer Science and Electronic Engineering, University of Essex, UK. Before joining in University of Essex at 2003, he worked at UCL on several EU research projects such as FAIN, MANTRIP, CONTEXT in the area of IP network management, active networks and context-aware services. Now his main research interests focus on heterogeneous wireless networks and their convergence with fixed networks such as PON (passive optical networks). Future network technologies such as network virtualization, cloud computing, pervasive service engineering are also within his research interest. He has published more than 60 journal papers and books, in addition to 60+ major conference papers. He manages research projects funded by EU FP7 (such as the EVANS project), EPSRC (e.g., PANDA, PAL, DANCER), and industries such as British Telecom (e.g., MOSE). He serves on the editorial boards of both IEEE and non-IEEE journals (Wiley or Springer). He is a Senior Member of IEEE and a Fellow of IET.
