Krill: an exploration in underwater sensor networks

While sensor networks have now become very popular on land, the underwater environment still poses some difficult problems. Communication is one of the difficult challenges under water. There are two options: optical and acoustic. We have designed an optical communication board that allows the Flecks to communicate optically. We have tested the resulting underwater sensor nodes in two different applications.
