摘要
近年来,海洋无线传感器的定位问题成为海洋无线传感器网络领域中的研究热点之一,并在导航、防灾等众多领域得到了广泛应用。本文对TDOA、Chan定位算法、最小平方算法及其优化定位算法等进行研究,并提出一种改进的TDOA算法,以提高海上无线传感器网络定位算法的精度。通过Matlab仿真工具,对本文提出的方法进行仿真,证明该方法的有效性。
In recent years,the localization of marine wireless sensor has become a hotspot in the field of wireless sensor networks,and has been widely used in many fields such as navigation,disaster prevention and so on. In this paper,TDOA,Chan location algorithm,minimum square algorithm and its optimization algorithm are studied,and an improved TDOA algorithm is proposed to improve the accuracy of the algorithm. And through the MATLAB simulation tool,the method is simulated and the validity of the method is proved.
