SOS, IoT standards, MQTT
Open Geospatial Consortium (OGC) standards
OGC(R) standards are technical documents that detail interfaces or encodings.
Sensor Observation Service (SOS)
The Sensor Observation Service (SOS) 2.0 is a web service interface specification for discovery and access of sensor observations, real-time or archived. Observations are returned encoded as O&M Observations, while information about sensors are returned encoded in SensorML.

SensorThings SWG
OGC has identified the need for standardized interfaces for sensors in the Web of Things (WoT). The Sensor Web interface for IoT SWG aims to develop such a standard based on existing WoT portals with consideration of the existing OGC Sensor Web Enablement (SWE) standards.

MQTT
MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport.
