Abstract
Description
The Victoria Experimental Network Under the Sea (VENUS) project will be deployed in three location by December 2006. This network provides telecommunication and internet access to the sea floor. It will be possible to connect a sensor network to a VENUS node in order to access data measured by the sensor network. An undersea sensor network could use acoustic or optical transmission. This paper investigates the use of high
intensity light emitting diodes as a transmission source for such a network. The criteria tested are energy conservation, path loss, viewing angle and minimum pulse width. The paper also provides a discussion of penetration by light in turbid coastal waters and a discussion of the potential for mutipath fading by transmitted light in sea water.
