NeTS-FIND: CogNet--An Experimental Protocol Stack for Cognitive Radio Networks and Its Integration with the Future Internet

Project Award Date: 09-15-2006


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).

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
