Abstract
Methods and systems providing application layer support for one or more sleeping nodes in constrained networks are contemplated. Embodiments contemplate inserting sleep information in a header option or payload of an application layer message. The application layer message may be conveyed in a hypertext transfer protocol (HTTP) or a constrained application protocol (CoAP). Embodiments contemplate communicating the application layer message to a server, which may serve as a caching and/or buffering proxy.
