Positioning Techniques for Underwater Visible Light Communication

Post-print of KICS Busan Branch Fall Conference 2016In this paper, a positioning scheme for Underwater Visible Light Communications (UVLC) is proposed. Using buoys as UVLC transmitters on the sea surface and any photodetector based receiver underwater, the position of the receiver is estimated using multilateration method based on received signal strength within the transmitter coverage. A numerical evaluation was carried out, which shows that the proposed positioning scheme has a high level of accuracy, compared with other underwater positioning schemes. It can be further be extended that Global Positioning System assisted intelligent buoys can be developed for UVLC positioning.
