2. RFID (Radio Frequency IDentification) and Wireless sensor network
(WSN) are two important wireless technologies that have wide variety
of applications and provide unlimited future potentials
RFID is used to detect presence and location of objects while WSN is
used to sense and monitor the environment.
The basic idea of integration of RFID with WSN is to connect the RFID
reader to an RF transceiver, which has routing function and can
forward information to and from other readers. Users are able to read
tags from distance 100-200m that is well beyond normal range of
readers.
3. Radio-frequency identification (RFID) uses electro-
magnetic fields to automatically identify and track tags
attached to objects.
The tags contain electronically stored information.
Passive tags collect energy from a nearby RFID reader’s interrogating radio
waves.
Active tags have a local power source such as a battery and may operate at
hundreds of meters from the RFID reader.
RFID tags are used in many industries, for example, an RFID tag attached to
an automobile during production can be used to track its progress through
the assembly line; RFID-tagged pharmaceuticals can be tracked through
warehouses; and implanting RFID microchips in livestock and pets allows
positive identification of animals.
4. A RFID system is made up of two parts: a tag or label and a
reader. RFID tags or labels are embedded with a transmitter
and a receiver. The RFID component on the tags have two
parts: a microchip that stores and processes information, and
an antenna to receive and transmit a signal. The tag contains
the specific serial number for one specific object.

Read Rate
Multiple (>100) tags can be read
simultaneously.
Tags can only be read manually, one at a
time.
Line of Sight
Items can be oriented in any direction,
as long as it is in the read range, and
direct line of sight is never required.
Scanner must physically see each item
directly to scan, and items must be
oriented in a very specific manner.
Human Capital
Virtually none. Once up and running,
the system is completely automated.
Large requirements. Labourers must scan
each tag.
Read/Write
Capability
More than just reading. Ability to read,
write, modify, and update.
Read only. Ability to read items and
nothing else.
Durability
High. Much better protected, and can
even be internally attached, so it can be
read in very harsh environments.
Low. Easily damaged or removed; cannot
be read if dirty or greasy.
Security
High. Difficult to replicate. Data can be
encrypted, password protected, or
include a “kill” feature to remove data
permanently, so information stored is
much more secure.
Low. Much easier to reproduce or
counterfeit.
13. The consumers are looking for the systems that are cheap, consume
less power, and having high level of security and safety features.
The use of semi-passive or active RFID technology in combination
with WSN has a promising future since reading range becomes much
larger.
RFID and WSN technology are the measures for the future of
Ubiquitous Computing. The field is still in its infancy and along with
the demand of the applications, we are definitely to see the allround
improvement in the sensing, transmission and detection, networking,
control theory, software, and middleware.
