Abstract

This paper proposes a RFID cell planning scheme for indoor location-awareness. We theoretically develop four objective functions that yield objective goals significant to the optimal design of a RFID cell topology and simulation is conducted to evaluate the performance of the proposed RFID cell planning scheme. We also evaluate the performance of the proposed technique after practically installing RFID readers in an indoor space to configure a RFID cell topology. Performance evaluations are conducted in terms of the following objective goals: minimal number of RFID readers for configuring a RFID cell topology, maximal RFID cell coverage areas for indoor location-awareness, minimal overlapping cells, and maximal indoor location-awareness accuracy.

본 논문에서는 실내 위치 인식을 고려한 RFID 기반 셀 구성 방안을 제안하였다. RFID 셀 구성을 위한 4개의 목적함수 설계 및 시뮬레이션 기반 성능 평가뿐만 아니라 RFID 리더를 실내 공간에 실제 배치하여 제안한 기법의 성능평가를 수행하였다. 성능 평가는 RFID 셀 구성에 필요한 최소 RFID 리더 수, 위치 인식이 가능한 최대 셀 영역, 셀 영역 간의 최소 중첩, 그리고 셀 영역의 최대 위치 인식 정확도 측면에서 수행되었다.
