This is a joint seminar between the School of Informatics and Institute for Digital Communications (IDCOM) in the School of Engineering.


Wireless technologies, such as IEEE 802.11, provide for multiple non-overlapping channels. However, wireless interfaces have limited capability, allowing each host to use only a small number of channels at any time. The focus of this talk is on the use of multiple channels within a single wireless network, despite limited interface capabilities. Based on asymptotic capacity results for constrained and unconstrained channel assignment models, we argue that substantial performance benefit can be obtained by suitably allocating the channel resources across the hosts. The talk will also discuss insights on protocol design, as well as issues in practical implementation of multi-channel wireless networks.


Nitin Vaidya is a Professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. His research interests span distributed algorithms, fault-tolerant computing, and wireless networks. Nitin has held visiting positions at Technicolor Paris Lab, TU-Berlin, IIT-Bombay, Microsoft Research-Redmond, and Sun Microsystems, as well as a faculty position at the Texas A&M University. He has co-authored papers that received awards at several conferences, including 2007 ACM MobiHoc and 1998 ACM MobiCom. He has served as the Editor-in-Chief for the IEEE Transactions on Mobile Computing. Nitin is a Fellow of the IEEE.
