Research on Core Techniques of Underwater Acoustic Sensor Network Node Localization

Abstract

进入新世纪以来,随着陆地资源的日益枯竭,世界各国纷纷把目光投向海洋这一蕴藏丰富资源的宝库。海洋是人类生存活动十分重要的领域,随着人类社会的不断发展,人们需要借助海洋中部署水声传感器网络进行海洋研究。由于水声信道是一个十分复杂的时-空-频变参随机多径传输的信道,加上它的环境噪声高、带宽窄、可适用的载波频率低和传输的时延大等特点,使得水声传感器网络面临着一些特殊的挑战,这些挑战要求新的架构和协议来保证水声传感器网络的传输性能。 水声传感器网络节点定位技术作为水声传感器网络的关键技术之一,在数据标识和收集、水下节点跟踪和探测目标节点位置信息等方面都有广泛的应用,并且水声传感器网络节点定位还可以用来...Since the new century, as the increasing depletion of the land resource, many countries put their attention to the rich marine resources. The ocean is very important field of people’s activities. With the continuous development of human society, people need to do the marine research in the ocean using the underwater acoustic network. Because the underwater acoustic channel is very complicated with...学位:工学博士院系专业:信息科学与技术学院_通信与信息系统学号:2332010015404
