While coordination algorithms for task allocation use only local sensing , these algorithms do not take advantage of the underwater acoustic network
capability and formal analysis tools are lacking.
The comparison between Terrestrial Wireless Sensor Network (TWSN), Underwater Acoustic Network
(UAN) and Underwater Wireless Sensor Network (UWSN) is given in section 3.
Another study mainly worked on communications in an ad hoc underwater acoustic network
Although underwater acoustic network
has continued to be studied for decades, underwater networking and routing protocols are still at the infant stage of research.

The following simulations are conducted by Aqua-sim, which is an NS2-based simulator dedicated for underwater acoustic networks
. The simulation time is 2000 s in total, with the generated data following the Poisson distribution.
Akyildiz et al (2004, 2005) has said the major challenges in the design of Underwater Acoustic Networks
: Battery power is limited and usually batteries cannot be recharged, also because solar energy cannot be exploited; The available bandwidth is severely limited; Channel characteristics, including long and variable propagation delays, multi-path and fading problems; High bit error rates; Underwater sensors are prone to failures because of fouling, corrosion, etc.
