Biography: John Thompson received the PhD degree from the University of Edinburgh in 1996. Since September 1999, he has been on the academic staff at the School of Engineering at the University of Edinburgh. In October 2005, he was promoted to the position of reader, equivalent to assistant professor in the USA. His research interests currently include signal processing algorithms for wireless systems, antenna array techniques and multihop wireless communications. He has published approximately 200 papers to date including a number of invited papers, book chapters and tutorial talks, as well as co-authoring an undergraduate textbook on digital signal processing. He was the founding editor-in-chief of the IET Signal Processing journal in 2007. He was a technical programme co-chair for IEEE Globecom 2010 held in Miami and and also served in the same role for the IEEE International Conference on Communications (ICC), held in Glasgow in June 2007.
Talk:Green Radio for Energy Efficient Wireless Communications
Abstract: This presentation will discuss energy efficiency issues in current cellular systems operation, particularly targetting more energy efficient base-station and access points. Communications and computing technology currently represents one of the fastest growing sources of carbon dioxide emissions in the world. The talk will start by discussing energy efficiency issues in current wireless networks and pinpoint the reasons for reducing the energy per communicated bit for future networks. The talk will address both techniques to reduce energy consumption within individual base stations, as well as more energy efficient cellular networks. The talk will also present research findings on energy savings from the UK Mobile Virtual Centre of Excellence (MVCE) Green Radio project, a major industry-UK government funded research programme currently addressing these issues.

Biography: Jiro Katto received B.S., M.E. and Ph.D. degrees in electrical engineering from University of Tokyo in 1987, 1989 and 1992, respectively. He worked for NEC Corporation from 1992 to 1999. He was also a visiting scholar at Princeton University, NJ, USA, from 1996 to 1997. He then joined Waseda University in 1999. Since 2004, he has been a professor of the Department of Computer Science, Science and Engineering, Waseda University. He has also been a director of the Electronic and Information Technology Development Department, New Energy and Industrial Technology Development Organization from 2004 to 2008. His research interest is in the field of multimedia communication systems and multimedia signal processing.
Talk:Multimedia transport technologies over wired/wireless networks
Abstract:This presentation discusses research topics about the transport protocols which have been designed for wired and wireless networks. Recently, fast and broadband networks are deployed all over the world and, simultaneously, new communication methods which have not been sufficiently investigated appears such as underwater sensor networks. Live video streaming services had been conveyed by RTP/UDP stacks but, recently, they are transmitted by HTTP/TCP stacks such as YouTube and Ustream. On the other hand, mobile video transport is still challenging over wireless and sensor networks due to their different media access mechanisms from the wired case. This presentation also refers to possible integration of the transport protocol design.
