水下无线传感器网络定位技术综述

摘要

With the rising of marine resources development and the rapid development of terrestrial wireless sensor net⁃works,underwater wireless sensor networks have become a new hot research area. The underwater wireless sensor network node location technology is the key technology for underwater wireless sensor networks. In order to make an in⁃depth research on un⁃derwater location technology,the paper elaborates the existing underwater location technologies by categories,compares their ad⁃vantages and disadvantages,and makes a discussion of the application scene of these techniques. Finally,the development trend of underwater location technologies is discussed.%　　随着开发海洋资源热潮的兴起和陆地无线传感器网络研究的迅速发展，水下无线传感器网络的研究已经成为新的研究热点。水下定位技术是水下传感器网络关键性支撑技术。为了对水下定位技术进行深入研究，采用分类总结的方法对目前已有的水下定位技术按类别进行了阐述，比较了它们的优缺点，讨论了这些技术适用的应用场景。最后对水下定位的发展趋势做出了展望。
