Abstract:
6LoWPAN networks rely on application protocols like CoAP to enable
RESTful communications in constrained environments. Many of these
networks make use of "Sleepy Nodes": battery powered devices that
switch off their (radio) interface during most of the time to
conserve battery energy. As a result of this, Sleepy Nodes cannot be
reached most of the time. This fact prevents using normal
communication patterns as specified in the CoRE group, since the
server-model is not applicable to these devices. This document
discusses and specifies an architecture to support Sleepy Nodes such
as battery-powered sensors in 6LoWPAN networks with the goal of
guiding and stimulating the discussion on Sleepy Nodes support for
CoAP in the CoRE WG.
