Abstract: In this paper, a node’s wireless optical communication module scheme for underwater wireless sensor
networks is presented and partly realized. And a distance measurement and 2-Dimension localization algorithm is
integrated in the scheme. The module scheme has the following features: the module consists of multiple optical
transceivers for omni-direction communication; it can keep data transmission reliable by automatically switching the
transceivers in case of nodes’ relative position change. Two photodiodes, which detect the optical signal strength for
distance estimation, are installed on each transceiver. The 2-Dimension relative positioning among nodes can be
calculated by the detected optical signal strength of the photodiodes.
Keywords: wireless optical communication, underwater, distance measurement, localization
