Người trình bày: TS. Trần Hoàng Nguyên
Thời gian: 10 giờ 30 ngày 30/12/2016.
Địa điểm: Phòng họp Quận 1 (dự kiến).
We study resource allocation for wireless virtualized networks considering both the backhaul capacity of the infrastructure provider (InP) and the users’ quality-of-service (QoS) requirements. We focus on the proﬁt gained by a mobile virtual network operator (MVNO) which is a middleman who buys physical resource from the InP, bundling them into virtual resources called slides before selling off the service providers. The objective of the MVNO is to maximize its proﬁt while guaranteeing the backhaul constraint and users’ QoS by jointly allocating the slices and the uplink transmit power to the users. To solve the formulated mixed integer non-convex problem, we propose a distributed solution framework based on Lagrangian relaxation to a ﬁnd suboptimal decision about slice and transmit power allocations. We further propose a low-complexity solution based on the concept of a matching game that does not require any global information. Numerical results are provided to evaluate the performance of the proposed schemes.
Nguyen H. Tran received the BS degree from Hochiminh City University of Technology and Ph.D degree from Kyung Hee University, in electrical and computer engineering, in 2005 and 2011, respectively. Since 2012, he has been an Assistant Professor with Department of Computer Science and Engineering, Kyung Hee University. His research interest is to applying analytic techniques of optimization, game theory, and stochastic modelling to cutting-edge applications such as cloud and mobile-edge computing, datacenters, heterogeneous wireless networks, and big data for networks. He received the best Ph.D. thesis award in engineering in 2011 and best paper award at IEEE ICC 2016 and APNOMS 2016. He is the Editor of IEEE Transactions on Green Communications and Networking.
