ABSTRACT:
With the development of technology
and the continuous improvement of people's
living standard, people are in pursuit of
automated, intelligent and convenient control
systems. Automation or automatic control is
the use of various control systems for
operating equipment such as machinery,
processes in factories, boilers and heat
treating ovens, switching on telephone
networks, steering and stabilization of ships,
aircraft and other applications with minimal
or reduced human intervention. Automation
is not completed without wireless
communication. Wireless communication is
the transfer of information between two or
more points that are not connected by an
electrical conductor. Nowadays server based
remote car control system plays an important
role in day-to-day life. In this paper
advancement is introduced in remote
controlled car using ANDROID mobile
phone. Remote control involves controlling
the car and tracking the car’s position. The
new idea introduced is used to reduce the
workload of a server and to reduce the time
required. In this method server workloads is
reduced by making a communication
between user’s mobile phone and the module
in the vehicle through internet.
INTRODUCTION:
Nowadays smart phones are becoming
more powerful with reinforced processors, larger
storage capacities, richer entertainment function
and more communication methods. In recent
years, an open-source platform Android has been
widely used in smart phones. Android has
complete software package consisting of an
operating system, middleware layer and core
applications. Different from other existing
platform like iOS (iPhone OS), it comes with
software development kit (SDK), which provides
essential tools and Application. Android is
a mobile operating system (OS), based on Linux
kernel and designed primarily
for touchscreen mobile devices.
The Internet is a massive network of
networks, a networking infrastructure. It
connects millions of computers together globally,
forming a network in which any computer can
communicate with any other computer as long as
they are both connected to the Internet. The
World Wide Web, is a way of accessing
information over the medium of the Internet. It is
an information-sharing model that is built on top
of the Internet. An Internet Protocol address (IP
address) is a numerical label assigned to each
device (e.g., computer, printer) participating in a
computer network that uses the Internet
Protocol for communication. An IP address

serves two principal functions: host or network
interface identification and location addressing.
Its role has been characterized as follows:
"A name indicates what we seek. An address
indicates where it is. A route indicates how to get
there.
With the help of internet, vehicle can be
tracked and controlled using android mobile.
A vehicle tracking system combines the use
of automatic vehicle location in individual
vehicles with software that collects these fleet
data for a comprehensive picture of vehicle
locations. Modern vehicle tracking systems
commonly use GPS technology for locating the
vehicle, but other types of automatic vehicle
location technology can also be used. Vehicle
information can be viewed on electronic
maps via the Internet or specialized software.
Urban public transit authorities are an
increasingly common user of vehicle tracking
systems, particularly in large cities.
Consider the system which consists of vehicle
module, server, and mobile phone. In order to
track the vehicle’s position remotely,
communication between mobile phone and
vehicle module is essential. Vehicle module
consists of GPRS unit for communication and
GPS unit for location identification. Mobile
phone should have GPRS facility for the purpose
of communication. If the user wants to track the
location of the vehicle or to control the
peripherals, the communication between mobile
and the module in the vehicle is needed. In
conventional method every second, mobile
communicates with the vehicle module
through server. Vehicle unit registers its IP
address in the server and mobile phone gets
the information from the vehicle unit through
server using IP address of the vehicle unit.
PROPOSED SYSTEM
In this proposed method, there are 2
modules. They are mobile module (i.e.) android
app and hardware module. First, the user needs
to install the android app in mobile phone.
Android app consists of 4 tabs such as vehicle
control page, Map view, Registration page,
Factors settings to configure the I/O devices to
the hardware module.

module
Control tab is used to control
peripherals of the vehicle. Map view tab is
used to view the vehicle’s current location in
map view. Registration page is used to
register IP address and port number of the
vehicle module in the server. Hardware
module consists of GPS, GPRS, ARM
processor, and analog input output pins. In
order to connect android app and hardware

module user should configure the device
using TCP/IP protocol. 16 digital I/O and 8
analog inputs in the hardware module are
used to establish connection between android
app and hardware module. These digital I/O
includes door control, engine control, parking
lamp control etc. 8 analog input includes fuel
level monitoring, air level monitoring, oil
level monitoring, etc. User should configure
these analog and digital pins by using TCP/IP
protocol. The processes involved in the
proposed system are classified into 3 stages:
First stage: Registration
Vehicle module’s IP address and port number
should be registered in the server.
Second stage: (Connection Request)
User (mobile phone) should receive the IP
address and port number of the vehicle
module through server.
Third stage: (Connection Establishment)
After getting the IP address, Mobile phone
will start to establish connection with the
vehicle unit directly without the help of
server.
First, vehicle unit register its IP address and
port number for the very first time in the
server. Mobile phone gets the IP address and
port number of vehicle unit through server
only once. After getting this IP address and
port number from the server, mobile phone
truncates the communication with the server
and starts to communicate with the vehicle
unit directly. Vehicle’s peripheral unit can
also be controlled through communication.
For example door can closed or opened and
AC in car can be switched ON or OFF
remotely. Port number is used for the
purpose of simultaneous communication (i.e)
more than one user can communicate with
the vehicle unit at the same time through
different port number. IP address is the one
which changes with respect to time. If the IP
address of the vehicle changed due to any
interruption, then vehicle unit disconnects
communication with the mobile phone. Now
mobile phone cannot track the location
information of the vehicle. To track the
location information, again the vehicle unit
should register the IP address in the server
and the mobile phone must get the IP address
and port number again for the purpose of
communication between them.

and track the vehicle remotely. These actions
are shown in the figures which have been

CONCLUSION
In this paper, advancement is introduced in
android based controlling and tracking the
car. This can be implemented to improve the
efficiency of the system compared with the
conventional system. Surely this method
reduces the workload of the server and the
time required to do operations.
