Positioning method and device based on wireless network, electronic equipment and medium

The embodiment of the invention provides a positioning method and device based on a wireless network, electronic equipment and a medium, and the method comprises the steps: determining a plurality of known nodes according to a wireless signal received by an unknown node; wherein the known nodes are nodes for periodically sending wireless signals; determining unavailable known nodes from the plurality of known nodes, and removing the unavailable known nodes from the plurality of known nodes to obtain an available known node set; determining the position of a known node in the available known node set, and determining a distance estimation value between the unknown node and the known node in the available known node set; and determining the position of the unknown node according to the position of the known node in the available known node set and the distance estimation value. According to the embodiment of the invention, the available node set is screened out to position the unknown node when the wireless net
