Under water wireless communication (UOWC). It is very inexpensive submarine
communications it presents numerous similarities compare to free space opitical(FSO).
Satellite links mainly due to the fact that they provide optical wavelengths to transfer secure
information between dedicated point to point links in this networks are feasible and it is easy
to operate at high data rates for medium distance upto a 100mts. information transfer is of
great interest to the military, industry, and the scientific community, as it plays an important
role in tactical surveillance, pollution monitoring, oil control and maintenance, off shore
explorations, climate change monitoring, oceanography research. In order to facilitate all
these activities, there is an increase in number of unmanned vehicles or devices deployed
under water, which requires band width and high capacity for information transfer
underwater. Although tremendous progress as been made in the field of acoustic
communication underwater, however it is limited by bandwidth. All these has led to the
proliferation of underwater optical wireless communication(UOWC), As it provides higher
data rates than the traditional acoustic communication systems with significantly lower power
and consumption and simpler computational complexities for short range wireless links. In
this paper, the main focus is to understand the feasibility and the reliability to high data rate
underwater optical links due to various propagation phenomena that impact the performance
of the system.
