Web of Things Core Concepts Paper

Together with Vlad and Erik Wilde, we’ve been trying since a while to write a scientific paper out of our common technical report that would sum up the founding concepts of the Web of Things. The paper finally got accepted for IoT 2010. This is a good sign because it emphasizes the fact that the Internet of Things community is now really looking into Web standards as a candidate common integration bus for the application layer of the physical world. A fact that did not really hold two years ago, when Erik’s attempt to publish a WoT paper at IoT 2008 did not succeed.

In a nutshell the paper is based on the fact that many efforts are currently centered around creating large-scale networks of “smart things” found in the physical world (e.g., wireless sensor and actuator networks, embedded devices, tagged objects). Rather than exposing real-world data and functionality through proprietary and tightly-coupled systems, in the paper we propose to make them an integral part of the Web. As a result, smart things become easier to build upon. Popular Web languages (e.g., HTML, Python, JavaScript, PHP) can be used to easily build applications involving smart things and users can leverage well-known Web mechanisms (e.g., browsing, searching, bookmarking, caching, linking) to interact and share these devices. In this paper, we begin by describing the Web of Things architecture and best-practices based on the
RESTful principles that have already contributed to the popular success, scalability, and modularity of the traditional Web. We then discuss several prototypes designed in accordance with these principles to connect environmental sensor nodes and an energy monitoring system to the World Wide Web. We finally show how Web-enabled smart things can be used in lightweight ad-hoc applications called “physical mashups”.

Enjoy the paper here, feedback is very welcomed!
