Document Type and Number:
WIPO Patent Application WO/2019/148801
Kind Code:
A1
Abstract:
Disclosed are a method and device for positioning a WSN node. The method comprises: determining a signal between an unknown node and a beacon node communicated with the unknown node in a WSN; determining a signal between any pixel unit and the beacon node communicated with the unknown node in the WSN; generating a target function according to the signal between the unknown node and the beacon node communicated with the unknown node, and the signal between any pixel unit and the beacon node communicated with the unknown node in the WSN; and searching for a target function value corresponding to any pixel unit signal in the WSN and positioning a pixel unit corresponding to the maximum target function value as the unknown node. By searching for a target function value corresponding to any pixel unit signal in a WSN and positioning a pixel unit corresponding to the maximum target function value as an unknown node, the node positioning having high precision and low energy consumption can be realized.
