This research focuses on cooperative control problems involving autonomous agents in uncertain environments with communication restrictions. Typical scenarios of interest involve different modalities of communication (e.g., high-bandwidth, high-rate communications for short range peer-to-peer interactions and low-bandwidth, and low-rate communications over larger distances). Agents must be able to intelligently adapt to the situation at hand and base decisions on the locally available (and uncertain) information, while still guaranteeing success of the overall mission. To accomplish this, the agents must be able to ascertain what information is important to ensure correct and appropriate decision-making for success of the overall mission objective. Furthermore, with the necessary information for mission success determined, the agents must be able to keep this information accurate and up-to-date given the changing (possibly distributed) communications restrictions. With such systems, analytical tools are needed to guarantee overall mission success given that decision-making is distributed with uncertainty. The overarching topics of interest for this research effort can be summarized as follows: value-of-information, distributed estimation, and distributed decision-making/control.
