Technical Summary
This document summarizes the main link-layer techniques and parameters that can be used for implementing energy-efficient networks with resource-constrained IoT devices. It also highlights the impact of such techniques on the upper layer protocols that have been developed at the IETF. This would enable implementers to fine-tune parameters at higher layers and together with the link-layer achieve energy-efficient behavior. The document also briefly provides an overview of energy-efficient tools available when using Constrained Application Protocol (CoAP) at the application layer. Its purpose is to provide information only, so Informational is the appropriate target status. The document in its current form meets the quality requirements to be understandable by the community. All references are identified as either normative or informational. All normative references are to existing standards and RFC documents. This document does not change the status of any existing RFCs. The document has no requests for IANA.
Working Group Summary
The first version of this draft was submitted as an individual draft in 2013 with the goal of providing guidelines for implementers of higher layer IETF protocols . The draft has been presented at several WG meetings of the IETF (IETF 88, IETF 91) where it received support. The result was confirmed on the mailing list in March 2014 with support from Ari, Esko and others. Based on discussion on the mailing list, a section on power saving techniques for DECT-ULE was added and the section on IEEE 802.15.4e DSME was removed. There was a discussion on the list in July 2014 about how detailed and comprehensive information should be provided for the different link-layer technologies. The authors decided that the current level is good and there were no objections on the list. There is consensus in the WG, and the document has received sufficient review.
Document Quality
The document has received sufficient review inside the WG as well as the Internet and IoT directorates.
