This paper describes the DiverNet system that allows real time reconstruction of diver's posture and its visualization using a virtual 3D model. DiverNet is a network consisting of 17 inertial sensors mounted on diver's body, enabling calculation of orientation of each body part. Based on the obtained data, diver posture can be visualized. In addition to that, DiverNet allows integration of additional...
This work addresses specific challenges posed by wireless communications for a Micro-Remotely Operated Vehicle (ROV). The majority of research within this field has primarily focussed on reliable acoustic links for navigation purposes and low data rate communications for critical status updates (<100bps). However, the feedback sent from the vehicle to the surface is often limited during operation...
This paper explores possible approaches to very low power, environmentally friendly underwater acoustic communications with signals that are well disguised in the background noise. While the underwater acoustic spectrum is currently not regulated, it is likely that it will be in the future, both to ensure human activities have minimal impact on marine wildlife and to minimise interference with other...
Over the last decade, vast improvements have been made in overcoming Inter Symbol Interference (ISI) in a dynamic underwater channel, with recent work focussing on multi-carrier systems due to their inherent multipath tolerance. However, the practical implementation of a bi-directional link for a micro remotely operated vehicle (ROV) presents additional complications. Erratic acceleration poses a...
