The Fourth ACM International Workshop on
UnderWater Networks (WUWNet)

In conjunction with ACM SenSys 2009
Tuesday November 3, 2009
Berkeley, California, USA

Sponsored by ACM SIGMOBILE


Workshop Details


Presentation format
Both long and short papers will be presented orally at the workshop. Long papers get a 20 min slot, while short papers get a 10 min slot. An extra few minutes for questions will be added to each slot.

Poster/demo setup
Posters and demos will be available for the entire workshop duration; the schedule also includes a dedicated block of time after lunch to give everyone an opportunity to visit all posters and demos. Poster boards will be provided (size approx. 40” x 30” = 102 cm x 76 cm).

WUWNet will be held on the campus of UC Berkeley in Bechtel Engineering Center (near Sibley auditorium). The technical sessions will be in Bechtel 102ABC (1st floor), and the poster/demo session in the Garbarini Lounge (2nd floor). 
There will be dedicated shuttle buses between the conference hotel (Doubletree Berkeley Marina) and Berkeley campus, at the start (7:15am, 7:45am, 8:15am, 8:45am) and end (5:30pm, 6:00pm, 6:30pm, 7:00pm) of the workshop. A schedule will be available at the hotel. However, if you need a parking space on campus, please email your request and a short motivation to the general chairs asap. Spots are severely limited and requests will be approved based on need.
For more information on the bus schedule and conference logistics, please look at this flier and this UC Berkeley campus map.

Water covers 71% of the earth's surface with oceans, rivers and lakes. Water systems are of vital importance to climate regulation, agriculture, nutrient production, oil retrieval and transportation, etc., yet they represent one of the least explored frontiers. As such, there is significant interest in real-time, in-situ monitoring of aquatic environments for scientific, environmental, commercial, safety and military applications.

Underwater networking has attracted strong attention in the recent few years. Although there is a long history of underwater acoustic communication, many new applications requires networking of multiple nodes, either static or mobile, and potentially over multiple hops. The physical challenges of acoustic channel and the complexity of diverse aquatic environments require us to completely re-think network design for underwater environments. Some major challenges at the physical layer and higher layers include the severely limited range-dependent bandwidth and attenuation, extensive time-varying multi-path propagation, the low speed of sound in water that is 5 orders of magnitude less than that of radio waves in air. In addition, underwater nodes are neither inexpensive nor easy to deploy. These distinct features yield grand challenges to every layer of the protocol suite in underwater networks.

The goal of WUWNet is to bring together researchers and practitioners in areas relevant to underwater networks. Thus, all layers of the protocol stack, from the physical layer to application, will be represented. Its objective is to serve as a forum for presenting state of the art research, exchanging ideas and experiences, and facilitating interaction and collaboration.
