Neighbor discovery-based positioning method, device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a positioning method and device based on neighbor discovery, an electronic device and a storage medium. The method is applied to a current node in a wireless communication system. The wireless communication system also includes: a neighbor node of a current node. The method comprises the following steps: sending the first detection information and recordinga first sending moment, receiving response information sent by a neighbor node of the current node and recording a first receiving moment, calculating the relative position of the current node and the neighbor node by using the first sending moment, the first receiving moment, the second sending moment and the second receiving moment; and if the difference between the first preset positioning level and the second preset positioning level is greater than 1, updating the first preset positioning level and calculating the absolute position of the current node by using the relative position and the absolute position of the neighbor node. According to the embodiment of the invention, the absolute position of the current node can be updated when the current node encounters the response information sent by the neighbor node with a high positioning level, so that the positioning error is reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a neighbor discovery-based positioning method, device, electronic equipment and storage medium. Background technique [0002] With the widespread promotion of wireless technology, people's demand for location-based information services has increased, and wireless positioning technology has attracted more and more researchers' attention. Among them, TOA-DOA (Time of Arrival-Direction of Arrival, time of arrival estimation- Direction of Arrival Estimation) joint positioning method is an important wireless network positioning technology. [0003] In an area, only one anchor node is needed to calculate the absolute position of other nodes in the area by using the TOA-DOA joint positioning method. The anchor node is a node whose absolute position is known, and the absolute position is an independent node without reference The geographical location, anchor nodes and other nodes...
