"A Low-Cost Acoustic Modem for Underwater Sensor Networks" by Ryan Kastner, Assistant Professor, Computer Science and Engineering; co-Director, UCSD-National Geographic Engineers for Exploration Program at Calit2
The aquatic research community is rapidly equipping ecological sites with a broad range of sensors and instruments. Advanced sensing systems provide the ability to perform a wide range of real-time, large-scale experiments to monitor complex ecosystem processes. However, the development of aquatic sensing networks is significantly lagging terrestrial counterparts. It is widely recognized that an aquatic counterpart to low cost wireless radios is needed to advance the state-of-the-art in underwater sensor networks. This talk provides an overall of our efforts to develop an acoustic modem for wireless underwater communication over short distances. The design target is a cost under $500, while supporting a data rate up to 200 bits/second up to 2 km distances with high power efficiency.
