位置測位アルゴリズムの改善によるZigBee屋内測位システムの実装と評価

抄録

Indoor localization cannot effectively be carried out by Global Positioning System (GPS). Recently, Zigbee is popularly used to locate a mobile object in an indoor environment. Most applications use Received Signal Strength Indication (RSSI) to figure out the distance between each node and then do localization. In this paper, a robust algorithm is proposed to enhance the accuracy of RSSI. This robust algorithm provides a stable and reliable RSSI for Indoor localization system. The results prove the proposed algorithm can increase the accuracy for indoor localization system.
