Embedded Devices Invade us!

Emergence of the physical Web Embedded devices get more

powerful. Real-world devices are getting

connected to the Web.

Problem: How to Achieve a Composable Web of Things?

Huge eco-system of devices.and… about 1000 systems to use

them and build applications on top of them.

How do we enable tech savvys and companies to create applications on top of this eco-system?

“re-think the way we design computing

systems in order to take into account the

>1000 smart objects per people we will soon

have to deal with.” David Orban

Contribution: Web of Things (WOT) in a Nutshell

Creating a Web of Things by: Connecting embedded devices to the Internet (IP) [2]. Having them embedding a Web-Server. Modelling their services in a Resource Oriented manner (RESTful API) so that they

become first-class citizens of the World Wide Web!

Benefits: Ease the building of applications on top of embedded devices. Get a lot of the features of the Web almost for free:

bookmarking, caching, linking, searching, securing etc. And enable physical mashups:

dynamic, ad-hoc composite applications involving embedded devices.

RESTful SunSPOTs

Turning the Sun SPOT platform into a Resource Oriented one: Each node embedds a tiny Webserver that

offers resources with JSON representations. A gateway (using RESTlet) is used to offer

additional functionality: Queue management, AJAX management

interface, HTML representation, etc.
