为有效解决传感器节点在水中的移动性问题，而节点移动主要是因为水流和随机干扰，提出了一种基于移动节点的定位算法--MNLS(移动节点定位算法)。移动节点定位算法是在分析现有相关定位算法的基础之上，提出了首先预测节点的运动轨迹，然后进行节点的测距与定位的算法思路。利用 MATLAB 对算法进行了仿真，实验结果表明 MNLS 与 Chan 算法相比较，单个节点的定位精度以及不同速度下节点的定位精度都得到了提高。因此，该算法对水下传感器网络定位有着实际的应用价值。

In order to effectively solve the sensors nodes mobility difficult problem in the water, the paper presents a localization algorithm based on mobile nodes-MNLS(mobile nodes localization algorithm). The main reasons of nodes mobility are the waterflow and random noise. The algorithm is on the basis of the analysis of the existing relevant localization algorithms, we present the idea which firstly forecasts nodes’ trajectory, then calculates the nodes’ distances and coordinates. The algorithm is simulated by MATLAB, and the results show that compared MNLS with Chan algorithm. The single node’s positioning accuracy and different speed nodes’ precision are all improved. So it has an application value for the underwater sensor network localization.
