Abstract
The present disclosure provides a wireless network-based positioning method and positioning apparatus. The positioning method includes: obtaining time information used for determining a current location of a to-be-positioned node, where the time information records times of arrival of a first sounding signal; determining time differences of arrival of the first sounding signal at the at least three anchor nodes according to recorded historical information and the time information; and determining the current location of the to-be-positioned node according to locations of the at least three anchor nodes and the time differences of arrival of the first sounding signal at the at least three anchor nodes. By means of the present disclosure, time differences of arrival of a sounding signal at different anchor nodes can be accurately determined, thereby determining an accurate location of a to-be-positioned node and avoiding synchronization between the anchor nodes.
