This is the kind of thing that some amateur radio operators somehwere have to start working on. I wonder if anyone in the ARRL is even aware that this kind of research is going on?

Cognitive radios present an exciting new frontier for the world of wireless telecommunications. Now Virginia Tech’s Center for Wireless Telecommunications (CWT) has received a three-year National Science Foundation (NSF) grant to extend its work in the field of cognitive radio to advance cognitive network capability.
Cognitive radios are like intelligent cell phones or police radios that can determine the best way to operate in any given situation. Instead of blindly following a set of predefined protocols, like regular radios, cognitive radios can now configure to their environment and their user’s needs.
The grant will fund research that will for the first time allow the radios to share a distributed knowledge base to use for individual and collective reasoning and learning. The research will have many important outcomes. First, a cognitive engine will be fully implemented in any wireless network, making it a cognitive one. Cognitive engines will be implemented into the widely available GNU radio, which is a low-cost software-defined radio developed specifically for experimentation in projects like this one. Finally, there will be a practical assessment of the performance advantages of cognitive wireless networks.
This grant was awarded through the NSF’s NetS Programmable Wireless Information Networks Program. Professor Charles W. Bostian is the principal investigator. Co-Pls are Associate Professor Michael Hsiao and Assistant Professor Allen MacKenzie in the the Bradley Department of Department of Electrical and Computer Engineering, and Economics Associate Professor Sheryl Ball. Additional sponsorship is provided by Anritsu Company, which will provide much needed testing and measurement equipment. The Virginia Tech researchers will use the equipment to prototype key cognitive radio functions and measure the performance of the resulting designs.
