ABSTRACT
With the rapid increase in the number of institutions as well as number of students in every
institution, it is very difficult to monitor whether the students are attending the classes as per the time
table or not. Even the students are in the campus but not present in the classes during the class hour.
In the existing system, presence of students in the class is being monitored by taking attendance
manually in the class. In this paper, we propose an intelligent student tracking system based on RFID
and ZigBee wireless network. The proposed system reads the RFID tags data through RFID reader,
and then sends it to PC node by a custom wireless protocol on the ZigBee. PC node gives
corresponding warning or hints by the result of matching master-slave RFID tag information. Here
each and every student is assigned with different RFID tags with individual tags numbers and the
RFID readers are placed in campus at different locations which identifies the persons coming to that
location by reading tag numbers of the students and intimates to the control room about their status.
Keywords: Microcontroller, RFID, Student Tracking, Zigbee.
1. INTRODUCTION
As the number of institutions as well as the number of students in each institution is
increasing it is harder to monitor the presence of students in class during the class hours. In existing
system students should be monitored continuously whether they are attending the classes or not
manually in the classes by means of taking attendance but there are many chances of student
escaping from different ways.
In the proposed paper, an intelligent campus student tracking system will be designed and
implemented based on the RFID and ZigBee network which keeps track of where the student moves
with in the campus. The system reads the RFID tags data through RFID reader, and then sends it to
PC node by a custom wireless protocol using ZigBee. PC node gives corresponding warning by

verifying with the time table stored in the database and updates the report table appropriately if the
student is anywhere else other than classroom during class hours.

Here each and every student is assigned with different RFID tags with individual tags
numbers and the RFID reader are placed in campus at different locations which identifies the
students moving from place to place automatically by reading tag numbers of the students and
intimates to the central server about their status.
The proposed system would help to keep track of whether the students are regularly attending
the classes or not. The main aim of this paper is to keep track of student’s movement within the
campus and also to provide a warning / update report table if student is outside the classroom during
class hours as per the timetable stored in the database.
2. RELATED WORKS
Intelligent campus security tracking system (iCST) [1] was designed and implemented based
on RFID and ZigBee network. iCST reads the RFID tags data through RFID ZigBee node, and
then sends it to PC node. PC node gives corresponding warning. When the warning occurs, user can
logon the web system to get the real-time tracking for valuables (with embedded slave RFID); where
the thief arrives any one access control node, it would be blocked. User can also manage his own
valuables such as lending and recovery operation through the Web manager centre.
Traditional methods of monitoring production in enterprises by humans on site are unable to
meet the expectations for efficiency, accuracy and cost as product lifecycles are shortened
continuously. Setting up an RFID and ZigBee based manufacturing monitoring system [2] is a good
approach to improve monitoring efficiency so as to improve management efficiency in enterprises.
RFID technology has been used to provide a more efficient way to identify and track items at
the various stages throughout the supply chain [3] in large retail industry. Real time traceability using
RFID technology on Lego Robot simulation environment and LabVIEW interface was developed
that can be similarly implemented in small and medium scale (SMI) industry.
Provides an overview of different services deployed in intra-organizational RFID [4] systems
and analyzes system architectures implemented today. We also compare emerging standards
developed by the EPC global community that aim to standardize system interfaces and reader
protocols in RFID deployments.
RFID and ZigBee based system architecture at the network level for tracking the vehicle
information [5] which has been sent to the centralized server will be developed. The aim is to
provide a simple and easy solution to track the location of the moving vehicle. Compared to the old
systems, ZigBee based network architecture is able to provide information about the vehicle
accurately. The vehicle will be having a unique RFID tag (Radio Frequency Identification). The
RFID reader is placed in particular places. For the beneficial features of RFID, we integrate RFID
readers into the Vehicle tracking Information System.
An information protection system [6] (named PC-guard) using systems engineering and
RFID technology. The login verification code can be notified in advance by using the PC-guard
system because every PC user having their own Auto-tag will be checked with PC RFID reader. The
information in the PC will be protected with RFID and the vibration sensor as the PC be turned on
and be invaded.
A Digital Campus Security System (DCST) [7] has been designed and implemented base on
the RFID, ZigBee and GSM network. DCST reads the RFID tags and sends information to PC node
through ZigBee network and gives alerts through GSM network. If any invalid RFID (Thief)
information comes into PC, user will logon the web system to get the real-time tracking for
valuables.
RFID based attendance system [8] is one of the solution for reducing the student’s overall
academic performance since taking attendance by calling names or signing on paper is very time

consuming and inefficient. This system can automatically capture student’s attendance by flashing
their card at RFID reader and save data in the PC.

In the proposed paper, the students will be continuously monitored for their presence in the
class room during the class hours. If he is in any other location other than class room during class
hours as per the time table stored in the database, a warning will be provided as well as the report
table will be updated for history purpose.
3. PROPOSED SYSTEM ARCHITECTURE
In the proposed system, following 4 different locations like “Class Room”, “Canteen”,
“Entrance” and “Rest Room” are considered where RFID readers are placed. Every student shall be
provided with an RFID tag, which he needs to keep with him all the time, while he is in the campus.
He will not be able to operate any doors (Entrance, Class Room, Rest Room, and Canteen) without
the RFID cards.
The front end HMI screen will be provided to manage the student database, Time table and
the report containing the information about presence of student in various places other than class
during class hours as per the time table.
The RFID readers placed at different locations, are connected to the serial ports of the
microcontroller. The microcontroller validates the data received by the RFID readers and sends the
RFID location through Zigbee wireless network to the PC.
The Application program in the PC validates the RFID student’s information with the time
table data stored. If student is present in any location other than “Class Room” during class hours as
per time table, the student’s information will be updated in to the report database.

The ZigBee is connected to PC through USB to Serial converter module
4.5 Sequence of operation
The sequential flow of system operations are described in following steps
When student swipes his RFID card in any location, the RFID reads sends the RFID
information to the microcontroller
Microcontroller then validates the RFID information, adds up the location ID and sends it to
PC through ZigBee wireless network
The application in PC receives the RFID location information, retrieves the time table to
verify the class timings
If student is present in any location other than class room during class hours as retrieved from
the time table, then the corresponding information will be updated to reports database.

6. CONCLUSION

As seen from the results, with the intelligent Campus Student Tracking System, we can track
and maintain a history of the student’s movement in various locations within the campus, during
class hours. This in-turn helps in improves the attendance of students in class room during class
hours.
Also History of the student’s absenteeism can be maintained in the report table over a period
of time (may be for a semester). If the student is not attending the classes, then from the data stored
in report database, parents can be updated with their ward’s history. Also an absenteeism report can
be sent to parents at regular intervals.
Implementation of this application is easier in the new upcoming institutions. The RFID
readers can be placed at suitable locations near the entrance of class rooms, library, rest room etc.
Even in the existing institutions also this can be implemented with additional work / cost.
Future Scope
Limitation of this project is that the student may skip showing of RFID cards at the RFID
reader location. A group of student may enter together, once one RFID is presented to the RFID
reader and the door opens. To avoid this in future, a camera can be installed at the entrance. The
student’s photo would also be captured in the database along with RFID tag. If a student enters any
location with-out swiping the RFID tag, then the camera can capture his photo, carry out image
processing and compare with the photo stored in database. Get their corresponding RFID tag and
present location. If a mismatch is found with respect to present location obtained from database and
the current location from RFID reader and camera, a warning message can be sent to the student as
well as any suitable actions can be taken.
Also with ZigBee, maximum distance for wireless communication is around 100 mtrs. If the
distance needs to be increased then networked ZigBee topology should be employed. This
Networked ZigBee topology affects the response time.
