The Department of Computer Science at the University of Cyprus cordially invites you to the Colloquium entitled:
The Future of Wireless Networks: On the Importance of Overhearing and Cooperation
Speaker: Dr. Lavy Libman
A fundamental feature of wireless communication is that it involves a broadcast medium, where any transmission can be heard, or unintentionally overheard, by any node within some area around the transmitter. Nevertheless, for many years, the dominant approach in the design, management and operation of wireless networks, which is evident in the vast majority of prevailing standards, has been to make the wireless medium resemble a wired link in every possible way, using classical techniques ranging from multiplexing and channel allocation to directional antennas. In the last few years, increasing interest started to emerge in approaches that aim to take advantage of the broadcast nature of the wireless medium and the ability of nodes to overhear their peers' transmissions, rather than treating it as a problem to be mitigated (interference). This talk will provide an overview of recent and emerging methods designed to make use of overheard information and allow nodes to cooperate in non-traditional ways in order to deliver it to its destination. Such methods, which include cooperative retransmission, opportunistic routing, and network coding, promise significant boosts in the capacity and reliability of wireless networks, and will become increasingly important in the future due to the exponential demand growth for wireless and mobile data communications, where traditional methods struggle to cope.
Lavy Libman received his B.Sc. degrees in Electrical Engineering and in Computer Engineering, and his M.Sc. and Ph.D. degrees in Electrical Engineering, from the Technion - Israel Institute of Technology in 1992, 1997, and 2003, respectively. In 2003, he joined National ICT Australia (NICTA) as a researcher in the Networks and Pervasive Computing program (now known as the Networks research group). In early 2009, he became a Senior Lecturer in the School of Information Technologies, University of Sydney, until October 2011. He is currently a Visiting Scientist at the Dept. of Electrical Engineering in the Technion. His research interests include all aspects of communication networks, and predominantly revolve around the design and performance optimisation of wireless networks, with a particular focus on cooperative and opportunistic techniques, protocols for resource-limited devices, and mechanisms for distributed coordination. He is Senior Member of the IEEE and its Communications Society and is serving as an associate editor of IEEE Transactions on Wireless Communications. He is a publicity co-chair of IEEE Infocom 2012, served as a technical program co-chair of ICCCN 2010 and WiOpt 2010, and continues to be involved as a program committee member of several major international conferences, including IEEE Infocom, IEEE LCN, ACM MSWiM, and WiOpt.
