More recently, the National Science Foundation (NSF) has started the Spectrum Innovation Initiative (SII). The goal of the initiative is to build an ecosystem for research related to dynamic and agile spectrum utilization. As part of our efforts to address the challenges that have been identified by this initiative, we built a framework which supports and facilitates experimentation and research of architectures and mechanisms for coordinated use of spectrum resources between collaborative wireless networks. The framework was built on COSMOS [3, 10], an advanced wireless testbed designed to support real-world experimentation of next-generation wireless technologies and applications. To showcase the framework’s capabilities, we also designed and carried out an experiment where the framework components were used to allow three different wireless networks to coordinate their spectrum usage via the exchange of messages carrying Spectrum Consumption Models (SCMs). The SCMs describe the characteristics and boundaries of spectrum usage of the devices in each network and facilitate the autonomous and dynamic selection of spectrum resources for each network in order to establish non-interfering communication links between the devices of each network. This kind of use of SCMs is a first of its kind in a civilian communications environment.

N2 - This paper describes a wireless experimentation framework for studying dynamic spectrum access mechanisms and an experiment that showcases its capabilities. The framework was built on COSMOS, an advanced wireless testbed designed to support real-world experimentation of next generation wireless technologies and applications. Our deployed framework supports experimentation over a large number of wireless networks, with a PUB-SUB based network interaction structure, based on the Collaborative Intelligent Radio Networks (CIRN) Interaction Language (CIL) developed by DARPA for the Spectrum Collaboration Challenge (SC2). As such, it enables interaction and message exchanges between the networks for the purposes of coordinating spectrum use. For our experiment, the message exchanges are aimed primarily for, but not limited to, Spectrum Consumption Model (SCM) messages. RF devices/systems use SCM messages which contain detailed information about their wireless transmission characteristics (i.e., spectrum mask, frequency, bandwidth, power and location) to determine their operational compatibility (non-interference) with prior transmitters and receivers, and to dynamically determine spectrum use characteristics for their own transmissions.
