Abstract:
Through dynamic access to the radio spectrum, cognitive radios (CRs) promise to provide reliable and programmable wireless communications whenever and wherever needed. Although the development of CRs is still in its infancy, the technology has already attracted a lot of attention from government agencies and private corporations, which have been pushing for accelerating the research pace in this area. To harvest the benefits of CRs, which include improved spectrum efficiency, spatial throughput, connectivity, network availability, etc., our wireless and networking group has been investigating resource management and protocol design issues in CR networks (CRNs). In this talk, I will provide an overview of our research activities in this domain, focusing on the design of channel access and routing protocols for CRNs. I will also discuss various optimization frameworks for resource allocation (i.e., spectrum/power/rate assignment) for such networks, and will briefly comment on a joint UA/Raytheon effort to build a network of small-factor, spectrum-agile radios for military applications.
Biography:
Marwan M. Krunz received the Ph.D. degree in electrical engineering from Michigan State University in July 1995. He joined the University of Arizona in January 1997, after a brief postdoctoral stint at the University of Maryland, College Park. He is currently a professor of electrical and computer engineering. He previously held visiting research positions at INRIA (Sophia Antipolis, France), HP Labs (Palo Alto, California), Paris VI University, and US West (now Qwest) Advanced Technologies (Boulder, Colorado). Dr. Krunz's research is in communications technology and networking, with particular emphasis on optimal resource allocation, adaptive control, and distributed protocol design. Recently, he has been involved in projects related to cognitive radio networks (CRNs); power/rate/spectrum adaptation for wireless networks; medium access control (MAC) design in wireless ad hoc networks; network protocols for wireless systems with adaptive MIMO, beam-forming antennas, and UWB capabilities; topology management and clustering in location-unaware sensor networks; adaptive video streaming over wireless networks; routing, fault monitoring, and detection in all-optical networks; path selection for MDC (multiple description coding) based media streaming; quality-of-service routing; WWW caching and prefetching; and adaptive packet encapsulation. Previously, he worked on packet scheduling and buffer management in switches and routers, QoS provisioning, effective-bandwidth theory, traffic characterization, and video-on-demand systems. He has published more than 120 journal articles and refereed conference papers (see Publications for details).
Dr. Krunz is a recipient of the National Science Foundation CAREER Award (1998-2002). He currently serves on the editorial board for the IEEE/ACM Transactions on Networking, the IEEE Transactions on Mobile Computing, and the Computer Communications Journal. He was a guest co-editor for special issues in IEEE Micro and IEEE Communications Magazines. He served as a technical program chair for the IEEE INFOCOM 2004 Conference, Hong Kong, March 2004, the IEEE International Conference on Sensor and Ad hoc Communications and Networks (SECON 2005), Santa Clara, Sep. 2005, the IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM 2006), Buffalo, New York, June 2006, and the 9th Hot Interconnects Symposium, San Francisco, California, August 2001. He has served and continues to serve on the executive and technical program committees of numerous international conferences, and on the panels of several NSF directorates. He was an invited speaker at several technical meetings and NSF workshops. He gave several tutorials at premier wireless networking conferences (e.g., MobiCom, MobiHoc). His research has been funded by NSF, Raytheon, the UA/ASU Center for Low Power Electronics, and the Connection One Consortium. Dr. Krunz is a senior member of the IEEE and a member of the ACM.
