Abstract
Radio Frequency Identification (RFID) is a method of remotely storing and
retrieving data using devices called RFID tags. RFID system components comprise
of RFID tag and RFID reader. The RFID tag stores a unique identification of the
object that is attached to it. However, it does not provide information about the
conditions of the object that it detects. Sensor node in Wireless Sensor Network
(WSN), on the other hand, provides information about the condition of the object and
its environment. Therefore, with the integration of RFID and WSN technology, their
disadvantages can be overcome and their advantages can be put into some important
applications. The anti-theft system is one of such application that can benefit from
the integration of technologies. The work presented in this thesis contributes to the
research of the motion sensitive 433 MHz active RFID system in several ways such
as (a) the development of novel interrupt-based motion sensitive RFID tag that send
data in real-time; (b) the design and development of low power RFID tag; and c) the
performance evaluation of RFID system in various aspects including maximum read
range measurement in indoor and outdoor environments, motion detection accuracy,
multi-tag communication efficiency and the estimation for power consumption of
the tag. This project is divided into two parts. The first part is the hardware design
and development of an active RFID system component; RFID reader and RFID tag.
The processes involved in designing the hardware include selection of components,
circuits design, PCBs layout, PCBs fabrication and components assembly. The RFID
tag and RFID reader prototype are successfully fabricated with the size of 55 mm x
45 mm x 27 mm and 95 mm x 97 mm x 24 mm, respectively. The second part is the
software design and development for RFID tag and RFID reader. The reader
operation adopts Basic Framed Slotted Aloha algorithm for multi-tag identification.
The RFID system employs multi-protocol such as Reader-Talks-First (RTF) and
Tag-Talks-First (TTF) for effective communication.
