International Workshop on Marine Sensors and Systems (MARSS 2014)
Sensor networks and sensor-based systems support many applications today on the ground. Underwater operations and applications are quite limited by comparison. Most applications refer to remotely controlled submersibles and wide-area data collection systems at a coarse granularity. UUnderwater sensor networks have many potential applications such as seismic, imaging of undersea oil fields, water pollution control, fish welfare monitoring, etc. Oceanographic research is also based on the advances in underwater data collection systems.
There are specific technical aspects to realize underwater applications which can not be borrowed from the ground-based sensors networks research. Radio has extremely limited propagation under the water. Acoustic telemetry could be used in underwater communication; however off-the-shelf acoustic modems are not recommended for underwater sensor networks with hundreds of nodes because they were designed for long-range. As the speed of light (radio) is five orders of magnitude higher than the speed of sound, there are fundamental implications of time synchronization and propagation delays for localization. Additionally, existing communication protocols are not designed to deal with long sleep times and they can not shut down and quickly restart.
The International Workshop on Marine Sensors and Systems, MarSS, brings together practitioners and researchers for discussion and work on the emerging aspects pertaining to the new mechanisms for underwater sensor networks and applications.
