Abstract
In order to get reliable communication no matter
under the water or above the surface, a kind of multi channel
and distributed wireless communication network architecture
for UUVs was presented. This network architecture includes
underwater communication, surface communication and
internal communication. Underwater communication is
acoustic modem, and the surface communication consists of
RF, Wi-Fi, BeiDou. Internal communication portal is
TCP/UDP. In order to avoid interference and decrease the
navigation resistance, a four-in-one compact antenna is
designed which is installed on UUV s inverted pole style
elevating mechanism. Through repeated tests in Qiandao lake,
Zhejiang province, the acoustic communication distance under
the water is validated to 11.2km
