Wireless localization method and apparatus with improved accuracy in various environment

摘要

It relates to a wireless positioning method and apparatus with improved location accuracy in various environments, comprising measuring the strength of at least one signal transmitted from at least one fixed node, and at least one received from at least one fixed node over a plurality of viewpoints. A plurality of peaks are detected in a signal intensity change pattern, a plurality of peaks are detected in a map in the form of a signal intensity distribution pattern in a region where a mobile node is located, and a plurality of peaks detected in at least one signal intensity change pattern Mobile nodes in various environments, such as environments with severe wireless environment changes, weak communication environments, or tunnel sections in which multiple repeaters are continuously installed, by determining the current location of the mobile node based on the comparison between the peak and the plurality of peaks detected on the map. The positioning accuracy of the can be greatly improved.
