Abstract :
In this paper, a nodepsilas 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 nodespsila 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.
