The invention particularly provides a multi-source marine Internet of Things positioning method, which belongs to the technical field of Internet of Things. The method comprises a setting buoy, a navigation mark, a building, and ship beacon nodes at different positions. An underwater node N is a node to be positioned, and the underwater node N broadcasts a positioning request to the beacon node, and the beacon node measures the distance between the beacon node and the underwater node N. The beacon node sends the attribute information and the position information of the beacon node, and the distance between the beacon node and the underwater node N to the underwater node N. The underwater node N determines the position of the underwater node N according to a polygon positioning principle. The multi-source marine Internet of Things positioning method is simple, low in cost and high in positioning precision.
Description
technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a multi-source marine Internet of Things positioning method. Background technique [0002] Positioning technology is one of the key technologies of the marine Internet of Things, which plays a huge role in navigation management, target tracking, and resource surveying. The marine Internet of Things adopts underwater acoustic communication, which is much more complicated than terrestrial wireless communication. It has the characteristics of long communication propagation delay, large delay variance, large propagation loss, serious multi-path phenomenon and Doppler dispersion, and high bit error rate. At this stage, the research on marine IoT positioning technology is very limited, and most of them are in the exploratory stage, which is an important technology that needs to be researched and developed urgently. [0003] The underwater positioning algorit...
