       Energy-Efficient Features of Internet of Things Protocols
                  draft-ietf-lwig-energy-efficient-08

Abstract

   This document describes the challenges for energy-efficient protocol
   operation on constrained devices and the current practices used to
   overcome those challenges.  It summarizes the main link-layer
   techniques used for energy-efficient networking, and it highlights
   the impact of such techniques on the upper layer protocols so that
   they can together achieve an energy efficient behavior.  The document
   also provides an overview of energy-efficient mechanisms available at
   each layer of the IETF protocol suite specified for constrained node
   networks.
