3. INTRODUCTION
Wireless Integrated Network Sensors (WINS) now
provide a new monitoring and control capability for
monitoring the borders of the country.
Using this concept we can easily identify a stranger or
some terrorists entering the border.
The border area is divided into number of nodes. Each
node is in contact with each other and with the main
node.
The noise produced by the foot-steps of the stranger
are collected using the sensor.
4. INTRODUCTION(CONT.)
This sensed signal is then converted into power spectral
density and the compare with reference value of our
convenience.
WINS require a microwatt of power so it is very cheaper than
other security system such as Radar and produce less amount
of delay.
It produce a less amount delay to detect the target.
It is reasonably faster.
On global scale wins will permit monitoring of land ,water
and air resources for environment monitoring
5. WINS System Architecture
WINS architecture includes sensor, data converter, signal
processing, and control functions.
The micro power components operate continuously for event
recognition, while the network interface operates at low duty
cycle.
6. WINS NODE ARCHITECTURE
The WINS node architecture is developed to enable continuous
sensing, event detection, and event identification at low power.
Lower power reliable & efficient network is obtained
with intelegent sensor nodes that include sensor signal
processing control wireless interface.

7. WINS NODE
ARCHITECTURE(CONT.)
WINS nodes are distributed at high density in an environment
to be monitored.
WINS node data is transferred over the asymmetric wireless
link to an end user
8. WINS MICRO SENSORS
The detector shown is the thermal detector. It just captures the
harmonic signals produced by the footsteps of the stranger
entering the border.
These signals are then converted into their PSD values and
are then compared with the reference values set by the user.

11. WINS DIGITAL SIGNAL
PROCESSING
if a stranger enters the border, his foot-steps will generate
harmonic signals. It can be detected as a characteristic feature
in a signal power spectrum. Thus, a spectrum analyzer must
be implemented in the WINS.
The spectrum analyzer resolves the WINS input data into a
low-resolution power spectrum.

12. WINS characteristics & application
Characteristics::
Support large numbers of sensor.
Dense sensor distributions .
These sensor are also developed to support short distance RF
communication.
Internet access to sensors, controls and processor.
13. APPLICATIONS
On a global scale, WINS will permit monitoring of land, water,
and air resources for environmental monitoring.
On a national scale, transportation systems, and borders will be
monitored for efficiency, safety, and security.
On a local, enterprise scale, WINS will create a manufacturing
information service for cost and quality control
14. PACKAGING
The sensor must be design to minimize the liklihood of
environment effect of wind, rain,snow etc.
The enclosure is manufacture from clear acrylic material

15. CONCLUSION
Application specific networking architectures .
Densely distributed sensor networks.
Development platforms are now available .
The network is self-monitoring and secure.
Now it is possible to secure the border with an invisible
wall of thousands or even millions of tiny interconnected sensors.
