Adaptive dynamic radio open-source intelligent team (ADROIT): Cognitively-controlled collaboration among SDR nodes

Abstract — We have created a sensor-sharing protocol that uses cognition to increase performance by choosing protocol parameters based on the current environment and the past relationships between environment and performance. We have constructed a prototype of the protocol, and experimented with it in a four-node outdoor testbed. Our testbed is part of a larger effort, ADROIT, which seeks to create cognitive teams of software-defined radios [1].

Adaptive dynamic radio open-source intelligent team (ADROIT): Cognitively-controlled collaboration among SDR nodes

Abstract — The ADROIT project is building an open-source software-defined data radio, intended to be controlled by cognitive applications. The goal is to create a system that enables teams of radios, where each radio both has its own cognitive controls and the ability to collaborate with other radios, to create cognitive radio teams. The desire to create cognitive radio teams, and the goal of having an open-source system, requires a rich and carefully architected system that provides great flexibility (enabling cognitive applications to change the radio’s behavior) and also has a clear structure (both so that others may add or enhance the software, and also so that the system can be clearly modeled for cognitive applications). What follows is a summary of the ADROIT system and the key architectural features intended to enable cognitive radio teams. 1 I
