Christine Yurie Kim Eminent Professor of Information Technology and Associate Chair for Graduate Studies and Research Dr. K. J. Ray Liu delivered a keynote address on June 3 at Virginia Tech’s 2011 Wireless Symposium in Blacksburg, VA. The focus of this three-day symposium is to assist professionals and academics in staying abreast of trends and current research in a rapidly changing, ever-expanding field.
His talk, titled “Cognitive Radio Games,” focused on recent advances in the use of game theoretical frameworks for cognitive radios in improving robustness and security. An intelligent wireless communication system, cognitive radio is aware of its surrounding environment and can adaptively change its operating parameters based on interactions with the environment and users. Using cognitive radio technology, it is plausible that future wireless devices will be able to sense and analyze their surrounding environment and user conditions, learn from the environmental variations, and adapt their operating parameters to achieve highly reliable communications and efficient utilization of spectrum resources.
Supported by International Wireless Communications Expo (IWCE), Virginia Tech’s 21st Wireless Symposium and 7th Annual Summer School offered oral presentations on networks, cognitive radios, and multi-antenna systems. Paper and poster presentations represented the latest advances in wireless communications and networking research. The Summer School offered 12 half-day tutorials in wireless basics and breakthroughs.
