Abstract: This paper describes how a passive radio frequency identification (RFID) system, used for tracking individuals inside a building, is designed and how it is integrated within a ZigBee sensor network. The different possible options for the design of the data acquisition and of the data transport functionality are taken under consideration. As a practical example, we have focused on a system that is capable of detecting when dementing elderly people are trying to leave the rest-home. In order to optimize issues such as privacy and comfort, we have integrated a thin passive RFID tag in the sole of the shoes. Another important aspect, often encountered during the design of an RFID system, is the need for minimal infrastructural costs. Intelligent choices of the readers location and the usage of a wireless network to centralize the data can result in important installation cost reductions. We have chosen for a system with reader antennas under the doormat of each individual room and at each exit. Based on the system requirement for the data transport, we demonstrate that ZigBee is the optimal solution compared to other alternatives such as Bluetooth, Wireless Fidelity (Wi-Fi) and Power Line Communication (PLC).
