Prototyping Smart Appliances (L)
The Internet of Things is the idea of interconnecting everyday objects and
ideally we do this within the largest interconnected network we have, the Internet.
A benefit is that we will be able to easily and remotely access information
about our things and their environment (e.g., the status of the washing machine in the
basement or the occupancy of a room).
The same way, we will control actuators (e.g., lock the door or turn on the auxiliary heating of the
car parked outside).
With this information and control available, new applications will emerge
that increase quality of life and energy efficiency.
If we also apply the vision of the Web of Things
users could discover and configure their things conveniently with a tool already
integrated into their daily lives, the Web browser. Automation and even more
sophisticated applications would be realized in a Web 2.0 manner, i.e. by
simple scripting and creating mashups. All appliances would have a Web-frontend
to access their resources and functions that can be combined with services from the Internet.
We envision smart appliances to be a significant share of the Internet of Things.
They will be able to communicate, export their UI, and
provide an open API to all their information and functionalities such as the
remaining run time of your washing machine, the performance at your home
trainer, the light sensor of your TV, or control of your lights and heating.
A smart freezer for instance could activates its aggregate at the right time, when green energy from solar or wind
power plants is available and cheap.
A key challenge still is to connect constrained embedded devices, as we would
find them in smart appliances, at the application layer. While Web servers on
these devices or application-level gateways for proprietary device protocols are
possibile, these current solutions lack efficiency and openness, respectively.
Using an emerging IETF standard, the Constrained Application Protocol (CoAP), we
will prototype smart appliances that are directly accessable over an open, RESTful Web
The goal of this lab is to build our first prototypes of smart appliances.
They will be implemented with Contiki using
6LoWPAN and the REST example as starting point.
The hardware basis will be a modified
an attached Raven USB-Stick ("Jackdaw")
and different digital thermostats that have to be analyzed. A detailed work plan
can be found in the Project Wiki.
