T10: Mobile-Station and Base-Station Cooperation for Wireless Communications Friday, June 15, Afternoon
- Speakers:
- Lajos Hanzo, University of Southampton, UK
- Abstract:
- The limitations of MIMOs relying on co-located array-elements are highlighted and it is shown, how the single-antenna-aided cooperative mobiles may circumvent these limitations by forming MIMOs having distributed elements. This concept is also referred to a Virtual Antenna Arrays (VAA). Then the corresponding amplify-forward and decode-forward protocols as well as their hybrids are studied. Channel coding has to be specifically designed for the VAAs in order to prevent avalanche-like error-propagation. Hence sophisticated three-stage-concatenated iterative channel coding schemes are proposed and it is argued that in the absence of accurate channel information at the relays the best way forward might be to use multiple-symbol differential detection. Indeed, it is rather unrealistic to expect that an altrustically relaying handset would also accurately estimate the source-relay channel for the sake of high-integrity coherent detection. EXIT-chart-aided designs are used for creating near-capacity solutions and a range of future research directions as well as open problems are stated.

T11: Disruption/Delay Tolerant Mobile l Ad Hoc Networks Friday, June 15, Afternoon
- Speakers:
- Zhensheng Zhang, Boeing, USA
- Abstract:
- In mobile ad hoc networks, nodes are constantly in motion and/or operate on limited power. When nodes are in motion, links can be obstructed by intervening objects. To conserve power, links are shut down periodically, resulting in intermittent connectivity. Applications in intermittent connected networks must tolerate delays beyond conventional IP forwarding delays and these networks are referred to as delay/disruption tolerant networks (DTN). New protocols specifically for DTNs must be developed as existing protocols designed for the Internet do not work properly. In this tutorial, we will review different DTN architectures and different protocol stacks proposed, the Bundle Protocol (BP), the Convergence Layer (CL) protocols such as Licklider transmission protocol (LTP)-CL, TCP-CL and UDP-CL. We will also review the state of the art in routing in DTNs and categorize these routing protocols based on information used. Recent developments in erasure coding, network coding and social networks applied to DTNs are also described. New architectures for vehicular DTNs are presented. Applications of DTNs in machine to machine and off loading traffic from cellular networks are discussed. The tutorial also identifies open research issues and intends to motivate new research and development in this area.

Zhensheng Zhang received his Ph.D. in electrical engineering from UCLA. Dr. Zhang has over twenty years experience in design and analysis of network architecture, protocols and control algorithms in wireless networks. He is currently with Boeing (formerly SDRC), Principal Engineer, serving as Principal Investigator for several DOD projects. Before joining SDRC, he visited Microsoft Research in the summer of 2002 and worked at Sorrento Networks, Department of System Architecture, for 2 years, responsible for designing the next-generation optical metro networks using the GMPLS control framework. Prior to Sorrento Networks he was with Bell Laboratories, Lucent Technologies, focusing on research and development in wireless networks. Dr. Zhang severed as Editor of IEEE Transaction on Wireless Communications from 2002 to 2006, as the General Chair of Broadband Wireless Networking Symposium, October 2004. He also served as Guest Editor for the IEEE JSAC special issue on Overlay Networks, 2003 and the Journal of Wireless Networks issue on multimedia wireless networks, August 1996. His research interests include wireless ad hoc networks, wireless sensor networks. He has given many invited talks and tutorials on wireless ad hoc networks at various conferences. Dr. Zhang will serve as the IEEE Globecom2012 TPC Chair.
T12: Network Coding: From Theory to Practice Friday, June 15, Afternoon
- Speakers:
- Frank H. P. Fitzek, University of Aalborg, Denmark
Muriel Médard, Massachusetts Institute of Technology, USA - Abstract:
- The tutorial provides an introduction to the rapidly growing research area of network coding. Network coding allows intermediate nodes in a network to manipulate data, for example by sending out packets that are combinations of previously received packets instead of simply forwarding them. The initial theoretical results on network coding were followed by a wealth of applications in a number of different areas that show that the theoretical insights can be translated into practical gains. The tutorial is divided into three parts. The first part provides the participants with the theoretical tools necessary to understand the field of network coding and focuses on the underlying algebraic principles. It will also introduce distributed randomized network codes and discuss their properties. We will not assume any prior knowledge of advanced algebra or optimization. The second part of the tutorial gives an overview of the different application areas and discusses, which types of networking problems are amenable to network coding (and which aren't). Finally, we will discuss implementation aspects in real-world systems. Such systems may range from core network routers all the way down to mobile phones and tiny sensor nodes.
