Abstract

Recent advancements in terms of protocols and architectural design, bring us closer to realize the Internet of Things (IoT)/Web of Things (WoT) vision; with disruptive effects on the interaction between humans and reality. We detail the specific embedded devices requirements, highlighting how and whether the RESTful principles are able to satisfy them or should eventually evolve. We also analyze the current approaches undertaken by the Internet and resource-constrained environment’s protocols, to cover such requirements. In particular, the Constrained Application Protocol (CoAP) aims at enabling direct RESTful access to Internet-connected devices. We discuss its features and limitations, referring to the emerging problematic scenario of heterogeneous networks where HTTP, CoAP, and ad-hoc networks are interconnected. Common everyday embedded devices enter these sensor networks, as part of a global digital nervous system where everything can be measured, thus giving more control to the people over their own surroundings.
