Abstract

The use of autonomous vehicles for surveillance and maintenance of underwater facilities, together with the development of new sensors for underwater monitoring, is bringing up the need for new, fast, and cheap underwater communications solutions. Current solutions are based on acoustic communications which, despite their range, offer very low bitrates. Although Radio Frequency (RF) communications show very high attenuations in underwater environments, IEEE 802.11 networks can still be useful in the monitoring, surveillance and maintenance applications due to the high speed and low cost devices.
This paper evaluates the performance of an IEEE 802.11g network in fresh water using ns-3. The results show that high bitrate communications are possible up to 1.4 m. For scenarios involving point-to-multipoint communications, simulation results show the need to enable the RTS/CTS mechanism.
