APPARATUS AND METHOD FOR SEARCHING PATH IN INTERIOR SPACE USING BLE TECHNOLOGY

摘要

Disclosed are a route search device in an interior space based on the Bluetooth low energy (BLE) technology and a method thereof. The method includes: a step of collecting beacon node information installed inside and link information about connection between any neighboring two beacons; a step of checking user terminals with a signal intensity equal to or greater than a predefined value located near each beacon node for a certain period of time using the collected beacon node information; a step of calculating the link cost between any neighboring two beacons using the number of the checked user terminals; a step of searching for a route with the minimum cost based on the calculated cost information and the collected link information; and a step of transmitting the found route to a requester user terminal.
