Iris is the software radio platform we use for all our experimentation. It is a modular system that allows radios to be constructed in a lego like fashion from software or hardware components. The radios are reconfigurable in runtime. We typically use the USRP as the hardware frontend. Anyone who is interested can use Iris for research purposes. All our experimental work is based on Iris. A good overview can be found in the September 2010 IEEE Communications Magazine. It is entitled, ‘Iris: An Architecture for Cognitive Radio Networking Testbeds’. We had an Iris workshop this week in CTVR. The workshop was given by Paul Sutton and attended by a number of different collaborators of ours from the various FP7 projects and COST actions in which we are involved.
