Publish-Subscribe Deployment Option for NDN in the Constrained Internet

Abstract

   Constrained IoT devices often operate more efficiently in a loosely
   coupled environment without maintaining end-to-end connectivity
   between nodes.  Information Centric Networking naturally supports
   this demand by replicated data distribution and hop wise forwarding.
   This document outlines a deployment option for NDN in low-power and
   lossy networks (LLNs) that follows a publish-subscribe pattern.  The
   proposed protocol scheme simplifies name-based routing significantly
   and facilitates even large off-duty cycles for constrained nodes.

1.  Introduction

   In the emerging Internet of Things (IoT), it is expected that large
   quantities of very constrained sensors and actuators collect,
   communicate, and process massive amounts of machine data.  Early
   experiments with constrained nodes show promising results for
   different deployments of ICN communication [NDN-EXP].

   Characteristics of constrained nodes:

   o  Battery-powered with sleep cycles

   o  Failing nodes

   o  Low power lossy networks

   Challenges of NDN deployment [RFC7927]

   o  Complexity of name-based routing
