Retracted: Localization of Nearest-Neighbour and Multilateration Analyse Based on RFID

Localization has always been a topic of concern in transportation and construction management. Radio frequency identification (RFID) has promising potentials due to their practically unlimited identification capacity, lower power and light weight. The objective of this research is to develop localization algorithms using RFID technology and analyse which is possible algorithm indoor environment. To achieve this goal, this study derives multilateration and nearest-neighbour algorithms for localization. Different parameter including distance and RSSI between the antenna and the target tag is then calculated based on Received Signal Strength Indication and Phase Angle. To make the localization more accurate, this survey also analyse the localization results by using normal tags and Wireless Identification and Sensing Platform (WISP).
