节点定位是水下无线传感器网络（UWSNs）的基本任务。现有的水下定位方法大多依赖于测距精度。由于海洋环境条件特殊，信标节点难以准确部署。水声通信信道的窄带宽和高时延导致了较大的误差。为了减小测距误差，提高定位精度，提出了一种基于测距校正和惯性协调的定位算法。该算法可分为基于距离校正的定位算法（RCL）和基于惯性协调的定位算法（ICL）两部分。RCL利用节点位置之间的几何关系对测距误差进行校正，得到准确的节点位置。但是，当未知节点随着水流的移动而偏离部署区域时，在一定时间内无法与足够数量的信标节点进行通信。在这种情况下，节点使用ICL算法将位置数据与相邻节点的运动信息结合起来更新自己的位置。仿真结果表明，与现有的定位方法相比，该算法极大地提高了未知节点的定位精度。
Node localization is the basic task of underwater wireless sensor networks (UWSNs). Most of the existing underwater localization methods rely on ranging accuracy. Due to the special environment conditions in the ocean, beacon nodes are difficult to deploy accurately. The narrow bandwidth and high delay of the underwater acoustic communication channel lead to large errors. In order to reduce the ranging error and improve the positioning accuracy, we propose a localization algorithm based on ranging correction and inertial coordination. The algorithm can be divided into two parts, Range Correction based Localization algorithm (RCL) and Inertial Coordination based Localization algorithm (ICL). RCL uses the geometric relationship between the node positions to correct the ranging error and obtain the exact node position. However, when the unknown node deviates from the deployment area with the movement of the water flow, it cannot communicate with enough beacon nodes in a certain period of time. In this case, the node uses ICL algorithm to combine position data with motion information of neighbor nodes to update its position. The simulation results show that the proposed algorithm greatly improves the positioning accuracy of unknown nodes compared with the existing localization methods.
