Professor Hamid AghvamiHamid Aghvami joined the academic staff at King’s in 1984. In 1989 he was promoted to Reader, and in 1993 was promoted Professor in Telecommunications Engineering. He is presently the Director of the Centre for Telecommunications Research at King’s.
Professor Aghvami carries out consulting work on Digital Radio Communications Systems for British and International companies; he has published over 500 technical papers and given invited talks and courses the world over on various aspects of Personal and Mobile Radio Communications. He was Visiting Professor at NTT Radio Communication Systems Laboratories in 1990, Senior Research Fellow at BT Laboratories in 1998-1999, and was an Executive Advisor to Wireless Facilities Inc., USA, in 1996-2002. He is Managing Director of Wireless Multimedia Communications Ltd., his own consultancy company. Professor Aghvami leads an active research team working on numerous mobile and personal communications projects for third and fourth generation systems; these projects are supported both by government and industry. He was a member of the Board of Governors of the IEEE Communications Society in 2001-2003, was a Distinguished Lecturer of the IEEE Communications Society in 2004-2007, and has been member, Chairman, and Vice-Chairman of the technical programme and organising committees of a large number of international conferences. He is also founder of the International Symposium on Personal Indoor and Mobile Radio Communications (PIMRC), a major yearly conference attracting some 1,000 attendees. Professor Aghvami was awarded the IEEE Technical Committee on Personal Communications (TCPC) Recognition Award in 2005 for his outstanding technical contributions to the communications field, and for his service to the scientific and engineering communities. Professor Aghvami is a Fellow of the Royal Academy of Engineering, Fellow of the IET, Fellow of the IEEE, and in 2009 was awarded a Fellowship of the Wireless World Research Forum in recognition of his personal contributions to the wireless world, and for his research achievements as Director at the Centre for Telecommunications Research at King’s.

CROSS-LAYER DESIGN AND INTERACTIONS: THE CHALLENGES




It is now widely accepted that cross-layer optimization offers the potential to achieve vast performance and efficiency gains in wireless communications environments. For example, cross-layer interactions could improve the performance of transport layer protocols, thereby enhancing throughput at the transport/application layer (this is important, as upper-layer performance is what the user actually experiences); as another example, cross-layer optimization between higher and lower layers offers considerable potential for communications to be made more “green”, implying a significant reduction in energy consumptions of networks and devices.

The vision of all-IP wireless networks has been largely achieved. The question that now naturally arises is: What’s comes next? In our view, an architecture that facilitates cross-layer design is the next step forward in all-IP based wireless networking. In this talk, an overview is given on the potential for cross-layer information exchange, involving higher layers interacting with other layers of the protocol stack, to assist communication efficiency and performance, whereby the emphasis is on the transport and network layers. In addition, advanced network-layer functionalities that can be used to facilitate the efficient transfer of cross-layer parameters among network elements are discussed.

Finally covered are cross-layer designs for green communications. The emphasis here is on how new networking paradigms, such as Delay Tolerant Networking, can be utilized to reduce energy consumption for delay-insensitive traffic. This approach will still, nevertheless, allow for considerable capacity gains in the network.
