Packet-Based Estimation and Control

This project is focused on developing algorithms for multi-vehicle, cooperative surveillance and reconnaissance that operate in a modern net-centric environment. These algorithms take into account the packet-based nature of modern networks by coding information in a manner that makes the performance of the system robust to packet loss, variable latency, and repeated transmissions. Results to date include analysis and design of estimation and control algorithms in the presence of packet loss, distributed estimation and sensor fusion algorithms for networked environments, and development of sensor selection and coverage techniques for spatio-temporal planning. Applications include cooperative estimation, formation management, and semi-autonomous ISR.
