舰船无线传感器网络节点定位技术研究

Research of node positioning technology based on ship wireless sensor network

信息化技术正在快速发展,在船舶工业中出现了基于无线传感网技术的定位技术。通过无线传感网技术,人们能够从一定程度上弥补传统的岸基定位和GPS定位技术的不足,同时也获得了更好的定位精度和抗干扰能力。本文主要研究无线传感网定位技术的结构和工作原理,并提出一种改进型的分布式加权定位算法,极大地降低了舰船的定位误差。通过Matlab软件进行仿真验证,对无线传感网中的传统定位技术和改进的定位技术进行性能比较。仿真结果表明,改进后的定位算法具有良好的定位能力,应用前景广阔。

Information technology is developing fast, in the shipbuilding industry appeared positioning technology based on wireless sensor network technology. The wireless sensor network technology,people are able to make up for the lack of traditional shore-based positioning and GPS positioning technology to some extent,but also get a better positioning accuracy and anti-jamming capability. This paper studies the structure and working principle of wireless sensor network positioning technology,and proposes a modified weighted distributed localization algorithm,which greatly reduces the ship positioning error.Finally,the Matlab software simulation of wireless sensor networks in the traditional positioning technology and the proposed improvement techniques were compared. Simulation results show that the improved location algorithm has good performance,broad application prospects.
