SYSTEM AND METHOD FOR MANAGEMENT OF WIRELESS SENSOR NODE POSITION

摘要

PURPOSE: A system and a method for managing a wireless sensor node position are provided to make a correction formula for RSSI(Received Signal Strength Indication) measurement values based on a change of a distance value and measure a position of a node using the correction formula. CONSTITUTION: A plurality of fixed nodes(200-a~200-d) receives a message transmitted from a mobile node. A sync node(300) receives a message transmitted from the fixed nodes. The message is for fining the distance between the mobile node and the fixed node. A position managing server(400) produces the distance between the mobile node and the fixed node using the message collected from the sync node. The position managing server finds the position of the mobile node based on the distance value and a preset option.
