摘要
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。在水下无线传感器网络技术中,定位技术作为重要组成部分之一扮演者十分重要的角色。本文以水下无线传感器网络节点的可移动性为切入点,从固定定位算法、移动定位算法以及混合定位算法三个类型介绍了几种典型的定位算法,最后,文章还对水下无线传感器网络定位算法的研究方向进行了总结和展望。
With the rising of marine resources development and the rapid development of terrestrial wireless sensor net-works,Underwater Wireless Sensor Networks （UWSNs） have become a new hot research area. In UWSNs, localization is one ofmostimportant technologies since it plays a critical role in many applications. In this paper, we classify localization algorithms into three categories basedon sensor nodes＇ mobility： stationary localization algorithms, mobile localization algorithms and hybrid localization algorithms. Then we present a survey of several typical localization algorithms. At last, we make a simple summary and analyze future research directions of localization algorithms in UWSNs.
