RANGING AND POSITIONING METHOD APPLICABLE TO WSN HAVING SPARSE ANCHOR NODES
Document Type and Number:
WIPO Patent Application WO/2021/196656
Kind Code:
A1
Abstract:
Disclosed is a ranging and positioning method applicable to a WSN having sparse anchor nodes. The ranging and positioning method applicable to a WSN having sparse anchor nodes comprises: a positioning center acquiring coordinate parameters of anchor nodes and information of ranging between all sensing nodes in a network, constructing a positioning model, and generating a blind node positioning matrix; generating a fitness function according to the positioning model, and constructing an adaptive operator; and running an adaptive fireworks algorithm to perform iterative optimization, outputting optimal elite individuals, and parsing same into coordinates of all blind nodes. By utilizing information of ranging between all sensing nodes, in particular by incorporating information of ranging between blind nodes, the positioning model of the present invention significantly improves the positioning precision of sensing nodes, reduces the dependence on the density of anchor nodes, and can support positioning of both a two-dimensional plane and a three-dimensional space, so that the present positioning method can be well applied to a WSN having sparse anchor nodes.
