Workshop Schedule Information theory bridges mathematics and communication systems analysis. The point-to-point communication problem is fairly well understood today: researchers have developed a refined set of tools for designing and optimizing codes and protocols. In stark contrast, the analysis of communication networks is still a wide open problem because of the complex nature of the interactions permitted by multi-terminal systems. Our lack of understanding is reflected by the fact that most state-of-the-art communication networks are planned using point-to-point principles, and network considerations enter only at a later stage of design. Designing resource-efficient wireless networks requires a fundamental understanding of the mathematics underlying multi-terminal communication systems. One of the simplest such systems is a “three-body problem,” with a source, a destination, and a relay whose purpose is to assist the communication from the source to the destination. This seemingly simple communication problem has long resisted solution, but new insight has been gained recently. This workshop aims at bringing together researchers from engineering, computer science, and mathematics to discuss recent advances and promising directions for future research. In particular, the workshop will emphasize: physical-layer models performance metrics sensor networks code design resource allocation converse bounds historical perspectives multi-terminal information theory relaying via network coding While leading researchers in each of these areas are being invited to participate in the workshop, submissions of contributed posters of original work in each of these areas are also being solicited. Posters will be reviewed on the basis of an extended abstract (not exceeding 3 pages), submitted in PDF format to gastpar@eecs.berkeley.edu. The deadline for submission is February 1, 2006, with notification of decisions by March 1, 2006. Download a PDF file of the workshop announcement. Sponsored by:

Show Funding

To apply for funding, you must register by the funding application deadline displayed above.

Students, recent Ph.D.'s, women, and members of underrepresented minorities are particularly encouraged to apply. Funding awards are typically made 6 weeks before the workshop begins. Requests received after the funding deadline are considered only if additional funds become available.

Show Lodging

MSRI does not hire an outside company to make hotel reservations for our workshop participants, or share the names and email addresses of our participants with an outside party. If you are contacted by a business that claims to represent MSRI and offers to book a hotel room for you, it is likely a scam. Please do not accept their services.

MSRI has preferred rates at the Hotel Shattuck Plaza, depending on room availability. Guests can call the hotel's main line at 510-845-7300 and ask for the MSRI- Mathematical Science Research Institute discount. To book online visit this page (the MSRI rate will automatically be applied).

MSRI has preferred rates at the Graduate Berkeley, depending on room availability. Reservations may be made by calling 510-845-8981. When making reservations, guests must request the MSRI preferred rate. Enter in the Promo Code MSRI123 (this code is not case sensitive).

MSRI has preferred rates at the Berkeley Lab Guest House, depending on room availability. Reservations may be made by calling 510-495-8000 or directly on their website. Select "Affiliated with the Space Sciences Lab, Lawrence Hall of Science or MSRI." When prompted for your UC Contact/Host, please list Chris Marshall (coord@msri.org).

MSRI has a preferred rates at Easton Hall and Gibbs Hall, depending on room availability. Guests can call the Reservations line at 510-204-0732 and ask for the MSRI- Mathematical Science Research Inst. rate.
