Welcome to the Third International Workshop on Underwater Networks (WUWNet'08). Underwater Networking is an emerging area of research, which has a profound impact on many civilian and military applications including environmental monitoring, marine biology, earthquake detection, weather forecasting. Water systems are of vital importance to climate regulation, agriculture, nutrient production, oil retrieval and transportation, 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 require 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 five 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 call for papers attracted 26 submissions from the United States, Singapore, Italy, Switzerland, Norway, Canada and Tunisia. The program committee accepted 10 full-length papers and 5 short papers (to be presented as posters). We are also delighted to include an invited speaker, Dr. Hanumant Singh, of the Woods Hole Oceanographic Institution. The papers cover a variety of topics in underwater communications, networking, and applications. Specifically, they address acoustic modem technology, methods for localization, network topology, energy efficiency, media access control, routing protocols, and deployment considerations. We hope these proceedings will serve as a valuable reference for users, engineers, and researchers interested in underwater networks. The goal of WUWNet is, in fact, to bring together researchers and practitioners in all 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.

Underwater communications and AUVs: from the arctic to the equator and other places before, after and in between
From the early days of the Autonomous Ocean Sampling Networks (AOSN) researchers have tried to exploit the synergies that exist between underwater navigation, communications and adaptive control. Over the last ten years we have made slow but steady ...
Analysis of a simple multihop underwater acoustic network
A multihop underwater acoustic network, which consists of a series of equal-distance hops connected by relay transceivers in a tandem, is considered. Messages are originated as coded packets from a source node at one end, relayed (decoded and re-encoded)...
