System and Method of Collaborative Localization Using Short Range Wireless Communication Network Without Location Infrastructure

摘要

The present invention relates to a method and system for measuring a cooperative location based on a local area wireless communication network in an infrastructure-free environment that can effectively utilize a wireless positioning resource by performing positioning through cooperation among mobile nodes, A base station for managing a node list and a plurality of base stations for performing a mode switching of at least one of a first mode switching to a tag node or an anchor node and a second mode switching to a transmitting node or a receiving node based on a command of the base station And a positioning server for estimating positions of a plurality of mobile nodes based on data received from at least one of the mobile node and the plurality of mobile nodes or data received from the base station.
