In cognitive radio networks with multi-hop communication pathways for data and voice, spectrum occupancy is dynamically changing and is location-dependent (i.e., localized radio communications/interference) such that the receiver interference profile will vary at each node. These dynamic signal environment conditions pose a difficult spectrum utilization problem and it is critical to ensure secure and authenticated communication within the cognitive radio network. Another major challenge faced by developers who are transitioning algorithms and protocols to military grade hardware is the lack of a cross-layer based multi-hop testbed architecture that enables easy implementation of cross-layer technologies. These testbeds are essential to corroborate the results obtained in simulations and evaluate how to refine these algorithms to ensure a successful transition process. Some of the requirements of such a testbed include, a flexible cross-layer based protocol stack, modularity to integrate new algorithms with ease, framework to accommodate both centralized and distributed solutions, tools to monitor the performance of the network in real-time, and having the ability to run unsupervised scripted experiments over extended periods of time. Having such a testbed expedites the design and development process of next-generation wireless communication technologies destined for a military SDR systems.
