Wavelength-Adaptation Underwater Optical Wireless Sensor Network Using Visible Light Communications

Abstract

A wavelength-adaptation underwater optical wireless sensor network (UOWSN) is proposed for marine environment development and seafloor resources observation.The method of LED-based visible light communication (VLC) is employed for creating the wireless network among the sensor nodes, and each sensor node is a VLC transceiver.The LED is incoherent source, it can neither damage the marine creatures like as a coherent laser source nor lose the inherent high speediness of light radiation yet.The wavelength-adaptation technique is used to adaptive control seawater turbidity and marine environment which both have spatiotemporal change.The effectiveness of proposed UOWSN is demonstrated in the experiments of underwater one-to-one image transmissions.
