INTRODUCTION

• WIRE LESS INTEGRATED NETWORK SENSOR(WINS)

• WINS provide a new monitoring and control capability for monitoring the Border of the country.

• 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 resonably faster.• On global scale wins will permit monitoring of land ,water

and air resources for environment monitoring.

DEVELOPMENT OF WINS

• 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 os 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

REMBASS

• Remotely monitored battlefield sensor system(REMBASS)

• Use now a day in unattended ground sensor(UGS)

• These sensor used seismic-acoustic energy,infrared energy and magnetic field to detect enemy activity.

Physical Principles

• When are distributed sensors better?

A. Propagation laws for sensingAll signals decay with distance

e.g. electromagnetic waves in free space (~ 1/d2)

in other media (absorption, scattering, dispersion)

distant sensor requires costly operations

If the system is to detect objects reliably, it has to be distributed,

whatever the networking cost

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

• Applications: Industries, transportation,

and safety & security.

Design consideration

• Reliability• Energy :There are four way in which node

consume energy1. Sensing2. Computation3. Storing4. Communicating

• Sensing:Choosing right sensor for thr job can improve the system performance.

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.

Enclosure

Unanticipated faulty behavior

• 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.

Conclusion

• 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.
