Abstract:
For the last several years, researchers at Virginia Tech have been building cognitive radios. Recently, we have expanded these efforts in an attempt to build the first true cognitive network. This talk will begin by defining these terms, discussing our early success in building cognitive radios, and describing current challenges in extending this work into the higher layers of the protocol stack. After discussing our work on building real systems, I will describe our motivation for and progress in building a generalized cognitive engine to control such systems using an enhanced, distributed, localized genetic algorithm. I will also present some preliminary results in using this system to solve a channel and power allocation problem in an ad hoc network. Finally, I will discuss our recent results in applying game theory to analyze the interactions of cognitive radios. Specifically, I will present some results on game theoretic models of topology control and spectrum allocation in ad hoc networks.Seminar Location: The seminars are held at:
