In-Door Localization Using Orthogonal Antenna Direction

Seungwoo Jeon, Mikyung Choi, Bonghee Hong, and Joonho Kwon
Abstract—As the container traffic of the world is steadily increasing, the space of logistics warehouse that handles the traffic is expanding. To reduce time and cost needed to find the pallets, it is necessary to know the accurate location of pallets. However, the state-of-the-art techniques of using localization systems exactly cannot recognize its location due to diffraction, absorption and reflection of radio signals in the warehouse. We propose three methods for exactly and quickly identifying location of pallets inside logistics warehouse. The first proposal is to attach RFID(Radio Frequency Identification) tags at the ceiling of warehouse. The second proposal is OSLE(Onion Skin Location Estimation) algorithm to find location by that environment. The final proposal is OAD(Orthogonal Antenna Direction) algorithm to improved the accuracy result of OSLE algorithm. Through performance evaluation, it is concluded that the distance between real location and measured location of using OAD is closer than the distance of using OSLE.

Index Terms—OAD algorithm, OSLE algorithm, RFID tag.
