The TinyOS Alliance Steering Committee encourages anyone who is interested in, using, exploring or advancing TinyOS-based technologies to attend. There will be reports from the six existing TinyOS working groups, a session on new working group formation, and a series of interesting panels that bring industry and academia together to discuss the important challenges ahead. The focus of the event is ultimately on the community, its innovations, and its work, and so there are three ways to participate and share your accomplishments:

1. The contributions session. The session will begin with the contribution czars, Kevin Klues and Martin Leopold, talk about how you can bring your code into TinyOS for others to easily download, use, and extend. The majority of the session will be two-slide, three- minute presentations from members of the community describing work they've done and which others can use. All you need to do is bring your slides and get up to the microphone. Contributions to any version of TinyOS (pre-1.0, 1.0, 1.1, 2.0) are welcome.
2. The demo session. If you've built a new application, a new platform, have new technology or new research ideas that you want to demonstrate to the TinyOS community, this is a great forum for doing so. To register a demo, please email the demo chair, Lewis Girod (girod at nms.csail.mit.edu).
3. The working group formation session. Is there an area that you think bringing interested parties together to collaborate would help advance research and technology? This session provides an opportunity to present proposals for new working groups to the community, in order to gather support, interest, and momentum. The Steering Committee has recognized two working groups it thinks would be beneficial to form; if you have an idea, just have a few slides to let people know.

In addition to all of these sessions, the TTX4 will have the next release of TinyOS 2.0 (2.0.1), which will include a large number of advancements, including robust low-power operation for micaz and telos-family nodes, improved sensor board support, a beta version of network reprogramming, and a new way to very easily install TinyOS.

The event is free for students, and has a $50 registration fee for non-students; this fee is to cover costs for the coffee breaks and lunch which will be served.

On behalf of the TinyOS Steering Committee, the local organizer Matt Welsh, and the demo chair Lewis Girod, we all look forward to seeing you there.
