Interfacing Distributed Sensor Actuator Networks with the Physical World

WithShivakumar Sastry, S. Sitharama Iyengar

The interface between a distributed sensor-actuator network (DSAN) system and the physical world is the critical foundation that enables the nodes to acquire sensor data and effect actions in the environment. Rapid advances in a variety of disciplines offer us tiny devices—namely, microcontrollers, radio transceivers, sensors, and miniature actuators—that can be deeply embedded in applications. When coupled with advances in modeling, software, control theory, and real-time systems, such a collection of networked devices can sense and actuate the physical world to achieve novel system-level objectives.
