CoAP

The Constrained Application Protocol, defined in IETF RFC 7252, is a RESTful protocol for constrained devices over UDP, with an Observe extension (RFC 7641) that provides realtime resource notification. CoAP is used in industrial IoT and LPWAN deployments where MQTT's TCP overhead is undesirable.
