Wireless networks tend to not be either energy or bandwidth efficient. This is due to a lack of fundamental understanding of how to share wireless media among spatially distributed users. Historically, wireless channel access research has followed either a traditional information-theoretic approach that assumes perfect user coordination and ignores the modularized network architecture, or a traditional network-theoretic approach that largely focuses on access control protocols and ignores the impact of the physical layer. Ephremides’ research will bridge the gap between these two approaches by developing a theoretical foundation for channel access in distributed wireless systems.
“Theoretical Foundation of Distributed Wireless Channel Access” is a three-year, $250K National Science Foundation Collaborative Research grant.
