Some of tradeoff studies are presented in terms of price of anarchy, 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 communications, jamming/attacks and anti-jamming, standards activities in cognitive networks and current projects related to DSA.</p> <p>Biography:</p> <p>Dr. 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 network architecture, protocols and control algorithms. He is currently with Argon ST (formerly SDRC), Principal Scientist, Networking Research, serving as Principal Investigator for many Department of Defense (DOD) projects. He worked at Bell Laboratories, Lucent Technologies, and Columbia University, focusing on research and development in high speed networks and wireless networks. Dr. Zhang severed as Editor of IEEE Transaction on Wireless Communications from 2002 to 2006 and as Guest Editor for the IEEE JSAC special issue on Overlay Networks, 2003 and the Journal of Wireless Networks issue on multimedia wireless networks, 1996. He is an IEEE COMSOC distinguished lecturer (2010-2011) and will serve as IEEE Globecom 2012 Conference Technical Program Committee (TPC) Chair, to be held in Southern California. He has given many invited talks and tutorials on high speed networks and wireless networks at various conferences and institutes.</p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="http://meetings.vtools.ieee.org/meeting_view/list_meeting/3373">Website</a></li> </ul> </div>
