第六讲水下声学传感器网络的发展和应用

文章主要介绍了正在发展中的水下声学传感器网络的一些概念和发展现状.在回顾了水声通信和水下网络的发展历史之后，首先从网络拓扑结构出发，指出多跳对等网络是适合于水声应用的一种网络结构，接着根据网络协议栈的概念，说明水下声学传感器网络在各协议层上所涉及的问题，并从物理层面，分析了水声介质的特殊性，和水下声学传感器网络所面临的一些主要的技术挑战.介绍了组成水下传感器网络的关键部件，以美国海网（Seaweb）为例，给出了一个水声传感器网实现的实例，对它的年度实验进行了介绍，最后，给出了中国未来的发展应用前景.

Development and applications of underwater acoustic sensor network

The concepts and applications of developing Underwater Acoustic Sensor Network (UASN) were introduced. After a review of underwater acoustic communication and network in the past，firstly in view of network topology indicated that multiple hop peer-to-peer network is suitable for underwater network application. Secondly according to network protocol stack conception, illuminated the corresponding problems on each protocol layer in the UASN. Thirdly made a physical analysis for the special characteristics in the underwater channel and narrated the main technique challenge in the UASN. Next introduced the key components that the UASN comprise. Then provided an illustration of UASN concept by used “seaweb”as an example. Finally gave the perspective on development and application of the UASN in the future in China.
