LOCATION MEASUREMENT SYSTEM USING RSSI/REGION ESTIMATION AND LOCATION MEASUREMENT METHOD USING THE LOCATION MEASUREMENT SYSTEM

摘要

A location measurement system is provided to recognize location and reduce the time required for searching coordinates at table which is divided by areas. In a location measurement system, a blind node(Node9) to be fined out which receives wireless ID and RSSI value from a coordinate node while in the specific location within the given area and receiving respective wireless ID for dividing the region. A base node(Node10) receives respective wireless ID for dividing the region, wireless ID and RSSI value from the blind node. The wireless ID for dividing the region, wireless ID and RSSI value transmitted to base node is red out a table which is segmented by regions and the region of the blind node is determined. A server calculates the location of the blind node by averaging the wireless ID and RSSI value and searches coordinate having an RSSI value near to the calculated result.
