Title Toward Energy-Efficient Operation of Base Stations in Cellular Wireless Networks Kyuho Son, USC EEB 248, Wed Dec 14. 2pm. Abstract: Energy use of base stations (BSs) in cellular networks has lately become a vital design consideration, due to increased awareness of environmental and economic issues for mobile network operators. In this talk, we will introduce several network-level energy saving techniques in order to reduce energy consumption in BSs. Specifically, we present details on our recent developments toward green cellular networks, such as dynamic BS switching on/off, energy-aware user association, and component-level deceleration. We evaluate the performance of the proposed techniques through extensive simulations under various practical configurations, including a real 3G BS deployment topology, a real cellular traffic trace and a realistic power consumption model. We show that, compared to the conventional static BS operation that is prevalent today, the proposed techniques can yield significant energy savings. The talk is based on joint work with Bhaskar Krishnamachari, Yung Yi and Hongseok Kim. Bio: Kyuho Son is a postdoctoral fellow in the Department of Electrical Engineering at the University of Southern California (USC). Prior to coming to USC, he received his B.S., M.S. and Ph.D. degrees in electrical engineering from Korea Advanced Institute of Science and Technology (KAIST), in 2002, 2004 and 2010, respectively. From 2004 to 2005, he was a visiting researcher at Wireless Networking and Communication Group in the Department of Electrical and Computer Engineering at the University of Texas at Austin. His current research interests lie in the design, analysis and optimization of wireless networks, cognitive radio systems and smart grid.
