Abstract:
CoAP is a RESTful application protocol for constrained nodes and
networks. Through the Observe option, clients can observe changes in
the state of resources and obtain a current representation of the
last resource state. This document defines a new mechanism in CoAP
Observe so that a CoAP client can conditionally observe a resource on
a CoAP server, only being informed about state changes meeting a
specific condition or set of conditions. This offers possibilities
to extend network intelligence, enhance scalability, and optimize the
lifetime and performance in order to address the requirements from
the Constrained Nodes and Networks.
