Some of tradeoff studies are presented in terms of price of an archy\, which is defined as the price that a decentralized system should pay for not being coordinated. We will also present a brief overview of the security issues associated with DSA networks\, including communicat ions\, jamming/attacks and anti-jamming\, standards activities in cognit ive networks and current projects related to DSA. \;\n \;\nBiogra phy: \;\n \;\nDr. Zhensheng Zhang received his Ph.D. in electrical engineering from the University of California\, Los Angeles (UCLA). Dr. Zhang has over twenty years experience in design and analysis of networ k architecture\, protocols and control algorithms. He is currently with Argon ST (formerly SDRC)\, Principal Scientist\, Networking Research\, s erving as Principal Investigator for many Department of Defense (DOD) projects. He worked at Bell Laboratories\, Lucent Technologies\, and Col umbia University\, focusing on research and development in high speed ne tworks and wireless networks. Dr. Zhang severed as Editor of IEEE Transa ction on Wireless Communications from 2002 to 2006 and as Guest Editor f or the IEEE JSAC special issue on Overlay Networks\, 2003 and the Journa l of Wireless Networks issue on multimedia wireless networks\, 1996. He is an IEEE COMSOC distinguished lecturer (2010-2011) and will serve as I EEE Globecom 2012 Conference Technical Program Committee (TPC) Chair\, t o be held in Southern California. He has given many invited talks and t utorials on high speed networks and wireless networks at various confere nces and institutes. \;\n \;\n \n\nImported from: http://calagat or.org/events/1250459287 URL:http://meetings.vtools.ieee.org/meeting_view/list_meeting/3373 SUMMARY:IEEE Oregon - Cognitive Networks/Dynamic Spectrum Access in Wirel ess Networks LOCATION:Tektronix Bldg 38: 3025 SW Zworykin Avenue\, Beaverton Oregon 97 077 US SEQUENCE:4 END:VEVENT END:VCALENDAR
