1. Introduction
1.1. Overview
Constrained devices (also known as sensors, smart objects, or smart
devices) with limited CPU, memory, and power resources can be
connected to a network. It might be based on unreliable or lossy
channels, it may use wireless technologies with limited bandwidth and
a dynamic topology, or it may need the service of a gateway or proxy
to connect to the Internet. In other scenarios, the constrained
