The 2nd International Workshop on Ubiquitous UnderWater Sensor Network 2008 (UUWSN08)

Underwater Sensor Network (UWSN) has a lot of potential application areas such as ocean monitoring and disaster prevention. Whatever more than two-third of the surface of the earth is covered with the water including oceans, rivers and lakes, the oceans remain one of the last frontiers to be a treasure-house of resources. Oceans serve as the main arteries of transportation between continents, food supplier and natural resources retrieval such as oil and natural gas. Recently, researchers having a lot of studies for UWSN have been trying to apply sensor network concept to underwater environments to utilize in field of practical use such as resource inquiry, pollution supervision and catastrophe prevention. UWSN is a new area of ubiquitous sensor networks in underwater environments which has challenges to be overcome such in long propagation delay resulting from low speed of sound propagation, severely limited range-dependent bandwidth, attenuation and time-varying multipath propagation. All of the above distinct features of UWSN give birth to new challenges areas for every level of the network protocol suite. This workshop will support an opportunity for industry and academic professionals to discuss the latest issues and progress in the area of UWSN. The workshop will publish high quality papers which are closely related to the various theories and practical applications in UWSN. Furthermore, we hope that this workshop will provide us with a good chance to share creative ideas regarding UWSN with other researchers and engineers from institutions around the world. While UUWSN2008 is the 2 nd workshop for underwater sensor network, this year we have 27 papers initially submitted to this workshop and each paper has been carefully reviewed by the internationally organized UUWSN2008 Technical Program Committee (TPC) members – 3 reviewers for each paper. We selected only excellent 8 papers among them, representing an acceptance rate of under 30%. We congratulate the authors of accepted papers and regret a lot of high quality submissions could not be included, due to the limit in session organization. We have one keynote speech concerning ocean experiments in underwater acoustic networking fertilizing the content of our high quality program On behalf of the board of UUWSN2008 workshop, we appreciate for all the submission authors to the program. We are grateful that Prof. Jun-Hong Cui (University of Connecticut, US) accepted our invitation for the keynote presentation. We would also like to thank the TPC members and external reviewers for their efforts in reviewing the submissions. Finally, we would like to thank Prof. Zhijun Wang (Hong Kong Polytechnic Univ., Hong Kong) and Prof. Dakai Zhu (Univ. of Texas at San Antonio, USA), the workshop co-chair, for the guidance in the organization of this workshop.
