The Internet Architecture Board and the IETF Internet Area will hold a workshop
on the Friday, 25th March 2011 in Prague on the topic:
"Interconnecting Smart Objects with the Internet"
Attached to this workshop is a tutorial day on the same topic on Saturday, 26th
March 2011. Please find more information about it at:
Today's Internet is experienced by users as a set of applications, such as
email, instant messaging, and social networks. While these applications do not
require users to be present at the time of service execution in many cases they
are. There are also substantial differences in performance between the various
end devices, but in general end devices participating in the Internet are
considered to have high performance.
As we move forward with the interconnection of all kinds of devices via the
Internet, these characteristics will change. The term "Internet of Things"
denotes a trend where a large number of devices benefit from communication
services that use Internet protocols. Many of these devices are not directly
operated by humans, but exist as components in buildings, vehicles, and the
environment. There will be a lot of variation in the computing power, available
memory, and communications bandwidth between different types of devices.
Many of these devices provide new services or provide more value for previously
unconnected devices. Some devices have been connected in various legacy ways in
the past but are now migrating to the use of the Internet Protocol, sharing the
same communications medium between all applications and enabling rich
Much of this development can simply run on existing Internet protocols. For
instance, home entertainment and monitoring systems often offer a web interface
to the end user. In many cases the new, constrained environments can benefit
from additional protocols that help optimize the communications and lower the
computational requirements. Examples of standardization efforts targeted for
these environments include the "Constrained RESTful Environments (CoRE)", IPv6
over Low power WPAN (6LoWPAN)", and Routing Over Low power and Lossy networks
(ROLL)" working groups at the IETF.
This workshop aims to explore the experience and approaches taken by
researchers and developers of Internet technology, when considering the
characteristics of constrained devices. Engineers know that many design
considerations need to be taken into account when developing protocols and
architecture. Balancing between the conflicting goals of computing performance,
code size, economical incentives, and security is often difficult, as
illustrated by Clark, et al. in "Tussle in Cyberspace: Defining Tomorrow's
This workshop aims to discuss the experience and approaches taken when
designing protocols and architectures for interconnecting smart objects to the
Internet. To frame the discussion we suggest, as examples, to investigate the
area of integration in the following categories:
* Power efficiency
* Interworking between different technologies and network domains
* Usability and manageability
* Security and Privacy
The goal of the IETF is "to make the Internet work better" and the workshop
organizers are interested in receiving contributions that support this goal.
Results may lead to guidelines and recommendations, proposals for new standards
development, start of new research activities, and the documentation of best
current practices regarding implementation and configuration.
- Workshop Style
The workshop’s main focus will be on the discussions of technical topics. (This
is not a mini-conference where every author just briefly talks about their
In order to keep the group at a manageable size, participants are required to
submit a position paper as an expression of interest. Submitters of accepted
position papers will be invited to attend the workshop. Active participation
will be expected.
The workshop will be structured as a series of working sessions punctuated by
invited speakers who will present relevant background information or
controversial ideas that help participants reach a deeper understanding of the
subject. The organizing committee may ask submitters of particularly salient
papers to present their ideas and experiences at the workshop. For each slot,
there will be one or two invited controversial speakers, and group work on the
problem that’s identified, hopefully reaching either a deeper understanding of
the problem or some means of approaching it.
- Important Dates
Position papers must be submitted at latest February, 11th, 2011. Note: An
early submission allows us to provide you feedback!
Submitted position papers will be reviewed immediately by the program
organizers and an invitation to the workshop will be sent to one of the paper
authors. At the latest, invitations will be distributed by February, 25th.
This one-day workshop will take place on Friday, 25th March, 2011, right before
the 80th IETF meeting in Prague, which starts on Sunday, 27th March.
Independent of this workshop but relevant for the participants, are tutorial
events on Saturday, 26th March 2011. These tutorials will focus on ongoing IETF
efforts related to the IETF CoRE, ROLL, and 6LoWPAN working groups. More
details can be found at:
- Position Paper Requirements
Interested parties must submit a brief contribution describing their work or
approach, as it relates to the workshop theme. We welcome visionary ideas for
how to tackle the integration of constrained devices, as well as write-ups of
deployment experience, and lessons-learned from successful or failed attempts
at integrating these constrained devices with the Internet. Contributions are
not required to be original in content.
We solicit brief write-ups with 1 to 3 pages, formatted in HTML, PDF, or plain
text (for example as a submitted Internet Draft). We encourage paper authors to
limit themselves on the most important challenge. A focused message will be
key! Accepted position papers will be published (in addition to meeting
minutes, slides, and a workshop report).
Please send your position paper to
The planned date and location for the workshop is Friday, March 25th, in
Prague. Details about the meeting venue will be provided to the invited
workshop participants. During the breaks coffee and tea will be served.
There are no plans for remote participation. Minutes of discussions will be
available, and offers to organize audio recording would be gladly appreciated.
