Research will identify broad architecture and protocol design approaches for cognitive radio networks at both the local network and the global internetwork levels. This architectural study will aid in the design of control/management and data interfaces between cognitive radio nodes in a local network and between cognitive radio subnetworks and the global Internet. The second objective is to apply these architectural and protocol design results to prototype an open-source cognitive radio protocol (the CogNet stack). Researchers will use it for experimental evaluations on emerging cognitive radio platforms. In trying to identify an efficient and complete solution, researchers will examine control and management protocols, support for collaborative PRY, dynamic spectrum coordination, flexible MAC layer protocols, ad hoc group formation, and cross-layer adaptation.
Researchers intend to develop an open-source Linux-based CogNet software protocol stack. They will use the prototype with emerging cognitive radio platforms (such as the GNU/USRP2 radio to be used as the baseline, the KU agile radio or the LucentIWINLAB network-centric prototype). ITTC will make software available for community research. The prototype software is validated in two steps: first in a wireless local-area radio network scenario with moderate numbers of cognitive radio nodes, and later as part of several end-to-end experiments using a wide-area network testbed such as PlanetLab (and GENI in the future).
