Abstract A State-Based Language for Sensor-Actuator Networks

This paper introduces a language design for sensoractuator networks. The main features are communication by a soft-state abstraction and behavior control by periodic rule evaluation. These features enable a state-based, rather than event-based, style of programming. Dynamic changes to network configuration and failures of components are automatically handled by this approach. The design choices target applications which experience low-to-moderate rates of sensor input and which do not require extreme, low-latency sensor processing and actuation. Coordinated actuation is concisely expressed in this language.
