1 INTRODUCTION
The concept was first put forward by the Automatic
Identification (Auto-ID) Center founded at the
Massachusetts Institute of Technology (MIT) in
1999, which is used to solve the interconnected
problems from item to item, from human to item,
from human to human. The Internet of Things that is
considered as the third wave of world information
industry following the computer and Internet (Yang
and Gao, 2009) has arisen worldwide concerns.
Recent great progress has been made in the
development of the Internet of Things with the
major efforts of all countries based on their own
national situations. China is also highly focused on
the study on the Internet of Things, and the Ministry
of Industry and Information Technology has started
the study on new generation information technology
jointly with other organizations concerned in order
to form the policies and measures which support the
development of new generation information
technology.
With the development of the Internet of Things,
a large number of equipments for the Internet of
Things have emerged, of which RFID is widely used
in the Internet of Things since it is characterized by
its ability of reading tags at a distance, high reading
speed, identification of high-speed objects and
non-contact method. RFID technology is the core in
the systems of the Internet of Things, which is
regarded as one of the most important and promising
information technology in 21
st
century due to its
uniqueness and reliability (ITU, 2005).
2 OVERVIEW OF THE
INTERNET OF THINGS
The concept of “the Internet of Things” was first
proposed by Auto-ID in the United States in 1999.
In Nov. 2005, in the World Summit on the
Information Society (WSIS) held by Tunis,
International Telecommunication Union (ITU)
released ITU Internet reports 2005: Internet of
Things, which noted that the ubiquitous "Internet of
Things" heralding the dawn of communication era,
everything from tires to toothbrushes, from house to
paper towels could be communication range via the
Internet. In Nov. 2008, IBM put forward the
concept“Internet + Internet of Things = Wisdom of
the Earth”, President Obama said that the United
States would maintain and regain competitive
advantage in the 21
st
Century by technology of the
Internet of Things in response to the concept in Jan.
2009. In Aug. 2009, Premier Wen Jiabao proposed
“Sensing China” while doing research at sensor
network center in Wuxi City of Jiangsu Province,
China. The Internet of Things has brought a new
opportunity to the development and revolution in the
information field and will make great contributions
to solve the modern social problems. At present, the
commonly accepted definition of the Internet of

Things is: through the radio frequency identification
(RFID), infrared sensors, global positioning systems,
laser scanners and other information sensing device,
to connect any items with the Internet for
information exchange and communication according
to the agreed protocol so as to achieve intelligent
identification, location, tracking, monitoring of a
network. The conceptual model diagram of the
Internet of Things is shown in Figure 1.
Figure 1: Conceptual Model Diagrams of the Internet of
Things.
As can be seen in the above figure, the Internet
of Things makes use of sensing technology such as
RFID, sensors, two-dimensional code for
information acquisition, through integration of
wireless network with Internet to transmit the
real-time information to the users accurately, and
analyze and process vast amounts of data with
artificial intelligence technology so as to achieve
intelligent control for items.
3 RFID TECHNOLOGY
Radio-frequency identification (RFID) is a
non-contact automatic identification technology,
using RF signal to automatically recognize target
and access to relevant data. RFID can
identify the
items automatically and
multiple tags
simultaneously as well as high-speed moving
objects, even under poor working conditions. It is
an advanced automatic identification technology
currently.
As a result of different application, the
composition of RFID system is not the same, which
generally consists of three basic components:
RFID
tags, readers and computer communication
network. The composing principle is shown in
Figure 2.

Figure 2: RFID Reader Block Diagram.
Radio Frequency Identification (RFID) also
known as electronic tag consisting of coupling
element (antenna) and chips, is used as a data
storage device of RFID system. Each tag has a
unique electronic identification (ID) that is
frequently attached to the surface of the objects to be
identified to store the relevant information.
RFID reader also known as reader is mainly used
to read and erase the tag information, which can
receive and send radio signals with external antenna.
Reader can achieve the purpose of automatic
identification of objects, namely which can read and
identify the stored electronic data on the tag without
contact. Normally, RFID reader will read and
transmit the electronic tag information to the
computer connected with it to process the
corresponding data.
Computer communication network is mainly
used in collection and processing of electronic tag
and data after RFID reader read to perform
communication transfer function.
Most of RFID system follows the operating
principles of inductively coupling, first RF signals of
specific frequencies are sent from the RFID reader,
the electronic tag will be activated when it enters
into the magnetic field, and then transmit the tag
information through its antenna to the reader, after
the reader receives the information it decodes the
information, and then sends to the back-end
computer controller to carry out appropriate control
and processing according to different setting. All of
above activities are fulfilled with RFID
communication method.

following five components: tag layer, RF
communication layer, reader layer, Internet layer,
application system layer (the relationship with each
other is shown in Figure 3).
Figure 3: System of RFID-based Internet of Things.
Tag layer: it consists of two parts, items and
Radio Frequency Identification (RFID) tags attached
to the items. Each electronic tag has stored the
information to identify the item. RFID tags can be
divided into two categories according to power
supply: active and passive RFID tags.
RF communication layer: RFID is a non-contact
automatic identification technology, using RF signal
to automatically recognize target and access to
relevant data. First the reader sends RF signal of
specific frequency, the RFID tag will produce
induced current when it comes into the work area of
transmitting antenna, and then chips on the RFID
tags will be activated, next RF tags send out their
own information through the built- in antenna, when
the antenna of the system receives the carrier signal
sent by the tag, it will transmit to the reader by
antenna controller.
Reader layer: RFID reader is wireless transmitter
/ receiver set with antenna, for sending and receiving
radio signal, which are able to read/write operations
of RFID tag. It is mainly composed of two basic
functional blocks: the control unit and RF interface,
which is characterized by strong computing
capability and large storage space. Readers system
will demodulate and decode the RF signal received
from the tag layer, and then send via the internet to
the application system for appropriate processing.
Internet layer: in the systems of RFID-based
Internet of Things, communication is via radio
signals between the tag layer and reader layer, and
via the internet between reader layer and application
system layer.
Application system layer: the main function of
application system layer is to establish practical
application in all industries by integrating all
functions of underlying systems, such as in the fields
of intelligent transportation, item identification,
electronic tickets, anti-counterfeit of commodity,
urban intelligent management, identification,
agricultural food management. Since application
system generally includes back-end database
systems, which is mainly used to store the
information of RFID tags, this system is required to
have strong computing power and large storage
space.
5 APPLICATION OF SYSTEM OF
INTERNET OF THINGS BASED
ON RFID TECHNOLOGY
Owing to its uniquely identifying characteristic,
RFID tag has sparked the interest of people in the
application study on RFID-based technology, and
the Internet of Things has been a study hotspot at
present. In recent years, study and applications of
RFID have accelerated the pace in China, as the
national informatization pilot list released by the
National Development and Reform Commission in
2009 contains RFID project involving a number of
areas such as production, manufacturing, logistics,
warehousing, transportation, food security, mobile
payment, special equipment, electronic toll
collection (ETC), the Internet of Things is getting
closer to our lives.
The Internet of Things is widely used in many
fields, for example: in the municipal operation and
management, it is used to monitor conditions of key
infrastructure such as water, electricity, heat, gas and
underground pipelines, thereby improving the
municipal management level, it is also used to take
hold of situation of various types of vehicles and
personnel by means of video surveillance, sensor,
telecommunication system and Global Positioning
System (GPS) etc.; in the fields of agriculture and
food processing, via unified RFID and database
system, the Internet of Things can establish
agriculture by-products and food traceability system
so that concern of the real-time and dynamic
information are realized and any problems that arise
are handled in a timely manner; the Internet of
Things may also be applied in the transportation
area, using modern information technology to realize
the real-time monitor of traffic conditions,
automated toll of road, intelligent parking and
real-time online GPS vehicle tracking; in the
medical field, the Internet of Things may perform

the functions of medical supervision, drug
administration, medical electronic records
management, monitoring of plasma collection, etc.
Furthermore, the Internet of Things also plays an
important role in the public health emergency
management, home remote control, telemedicine,
security monitoring, etc, which greatly improves the
quality of life.
6 EXISTENT PROBLEMS IN THE
DEVELOPMENT OF THE
INTERNET OF THINGS
At present, the Internet of Things still has some
urgent problems which need to be resolved although
it has made our lives easier.
1) Standard Problem
First, because the Internet of Things is related to
wireless transmission that has lots of transmission
protocols, it is inevitable to integrate these protocols
for a more effective use. Second, there is no standard
architecture generally accepted for Internet of
Things so far, and lots of protocols have no common
interface either. Such problems have hindered the
development of the Internet of Things.
2) Price Problem
Owing to the higher cost of production of chips
for the Internet of Things at present, it is unrealistic
to attach this kind of identification chips with high
cost to all items. Moreover, the transformation of
existing products to meet the requirement of the
Internet of Things also has a relatively high cost and
needs huge investment. However, as the
development of technology and industrial upgrading
of industry of things of internet, the cost will
continue to decline gradually.
3) Security Problem
Since the small-sized items accessed to the
Internet of Things can not carry the higher frequen-
cies, more secure application can not be achieved.
Furthermore, due to the wide varieties of items
attached on the Internet of Things leading to close
connection and large amounts of data and personal
privacy transmitted over the Internet, the chief
problem is to ensure these information not be
cracked among the obstruction of the development
of the Internet of Things.
4) Problem of Policies and Regulations
Since the Internet of Things involves all kinds of
industries which need to be integrated, the state is
required to formulate the policies and legislation
suitable for this industry growth so as to guarantee
its normal and order development
7 CONCLUSIONS
With consideration of the above problems, the
Internet of Things needs to be developed
energetically by improving the relevant laws and
regulations as soon as possible, setting up uniform
standards and specifications, working out a set of
RFID standardization system, increasing the study
on the security of RFID, following the development
principles “with the application as the driving force,
technology as the core, and standardization as the
safeguard” so as to promote the whole industrial
chain development of the Internet of Thing.
