sMAP: Simple Monitoring and Actuation Profile

Xiaofan Jiang, Stephen Dawson-Haggerty, and David Culler


We present the architecture, specification, and implementations of a simple monitoring and action profile (sMAP), optimized for sensors, meters, and actuators in building environments. Our architecture is built on HTTP/REST and uses JSON as the object format for interoperability. We implement sMAP on a variety of resource monitors and actuators inside a commercial building, including mote-based wireless sensors and meters running IPv6/6LowPAN, Modbus based panel meters, and external data sources. We show that sMAP is widely implementable and efficient, and our API and schema definitions are expressive and concise. We demonstrate that our architecture is well suited for resource constrained devices using compressed JSON and proxies.
