摘要
随着水下观察和海洋观测系统的应用需求日益增长,水下无线通信和水下传感器网络技术迅速发展。这种技术将在研究气候变化、监控海洋、湖泊的生态环境的诸多方面发挥重要作用,并有助于海洋石油开采、无人水下航行器、潜艇、船舶、浮标以及救生员的水下作业。然而现有的水下声通信技术无法提供足够的高数据传输速率以满足研究和监控水下环境的需要,无线光通信是应对这种需求的最佳选择。介绍了目前水下无线传感器网络通信的应用需求,分析了用于水下传感器网络的无线光通信的特点,全面、详细地介绍了当前国内外水下无线光通信的发展现状,并总结了水下无线光通信的未来发展趋势。
The growing needs for underwater observation and subsea monitoring systems have stimulated considerable interests in advancing the enabling technologies of underwater wireless communication and underwater sensor networks. This communication technology is expected to play an important role in investigating climate change, monitoring biological, biogeochemical, evolutionary and ecological changes in the sea, ocean and lake environments, and help to control and maintain oil production facilities and harbors using unmanned underwater vehicles （UUVs）, submarines, ships, buoys and divers. However, the present technologies of underwater acoustic communication cannot provide the high data transmission speed required to investigate and monitor these environments and facilities.Optical wireless communication has been proposed as the best alternative to meet these challenges. Demands for wireless sensor network communication in underwater environments are introduced, and traits of optical wireless communication （OWC） for underwater sensor networks are analyzed. Present states of underwater OWC home and oversea are introduced detailedly in the round and future developing trends of underwater OWC are generalized.
