The Constrained Application Protocol, CoAP, and related extensions are intended to support machine-to-machine communication in systems where one or more nodes are resource constrained, in particular for low power wireless sensor networks. This document defines publish- subscribe message queuing functionality for CoAP that extends the capabilities for supporting nodes with long breaks in connectivity and/or up-time.
