Enabling large scale flexible deployment of cognitive radio routing protocols

Building large-scale testbeds for cognitive radio networks has been identified as one of the main challenging problems and basic needs for advancing cognitive radio research. The cost of buying and maintaining a large-scale cognitive radio networks using special RF interfaces can not be ignored. In this paper we introduce CogFrame, a framework that facilitates large-scale deployment of cognitive routing protocols by enabling the deployment of these protocols on off-the-shelf laptops nodes using their built-in Wi-Fi interfaces for RF communication. The framework is built on top on the Click modular router to ensure the easy of development of new protocols while providing new modules to handle cognitive radio functionalities.
