INTRODUCTION DEVELOPMENT OF WINS WINS SYSTEM ARCHITECTURE WORKING OF WINS WINS MICRO SENSOR WINS CHARACTERISTICS APPLICATIONS COMPARISION ADVANTAGES & DISADVANTAGES CONCLUSION

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. This sensed signal is then converted into power spectral density and the compared

with reference value of our convenience.

WINS Initiated in 1993 under Defence advance research project agency(DARPA)in US.

LWIM (Low power wireless integrated microsensor)program began in 1995 for further development of WINS sponsored by DARPA.

In 1998, WINS NG introduced for wide varity of application.

the LWIM project multihop, self-assembled, wireless network algorithms for operating at micropower levels.

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.

WORKING OF WINS

Routing is based on Shortest distance.

Traffic between nodes is considered.

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

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.

Thermal Infrared Detector

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.

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.

WINS require a microwatt of power so it is very cheaper than other security system such as Radar.

It produce a less amount delay to detect the target. It is reasonably faster. Compact geometry and low cost allows WINS to be

embedded and distributed at a small fraction of the cost of conventional wireline sensor and actuator systems

It is even used for short distance communication less than 1 Km

We experienced several failure as a result of undetectable, incorrectly download program and depeleted energy level etc.

For example node will detect false event when sensor board is overheated.

Densely distributed sensor networks. Application specific networking architectures 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.
