Energy-Efficient Features of Internet of Things Protocols
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.
