Abstract: | Comprised by a swarm of acoustically linked and cooperative autonomous underwater vehicles (AUVs) with onboard sensors, an
underwater mobile sensing network (UMSN) will be a complementary means to fixed observatory networks, e.g. seafloor observatory
networks and moored buoy arrays. It has obvious advantages over a single large AUV in higher efficiency due to parallel observation,
stronger robustness to vehicle failures and lower cost. Although an UMSN can be viewed as a counterpart of wireless mobile
sensing networks for air and terrestrial applications, it is much more challenging due to poor performance of underwater acoustic
communication, poor performance of underwater positioning and high degree of uncertainty in vehicle dynamics and underwater
environment. In order to verify key technologies involved in an UMSN, e.g. cooperation of multi-AUVs based on acoustic communication,
a low cost testbed has been developed for experimental study. The design of both hardware and software is introduced. Also
the results of a functional test for verification of the effectiveness of the testbed are presented. |
