It is becoming widely recognized that current approaches for allocating wireless spectrum can result in highly inefficient usage. Moreover, advances in technology, such as cognitive radio, offer the promise of implementing new more flexible spectrum sharing paradigms. These include the use of trading spectrum access on secondary markets or allowing for more various forms of open access. In this talk, we describe some simple economic-based mechanisms for such spectrum sharing approaches. We will consider both the case where a spectrum manager regulates access to a given band as well as the "open access" case where there is no manager. In the first case, we study various auction-mechanisms which the manager may use to allocate spectrum usage. In the second case, we give a distributed algorithm which the users must implement to manage spectrum access.
Randall Berry received the B.S. degree in Electrical Engineering from the University of Missouri-Rolla in 1993 and the M.S. and PhD degrees in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 1996 and 2000 respectively. Since 2000, he has been with Northwestern University where he is currently an associate professor in the Department of Electrical Engineering and Computer Science. In 1998 he was on the technical staff at MIT Lincoln Laboratory in the Advanced Networks Group. His primary research interests include wireless communication, data networks, and information theory. He is the recipient of a 2003 NSF CAREER award and the Best Teacher award for the 2001/2002 academic year from the ECE Department at Northwestern University.
