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 sensing All 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 • • 3. 4. 5. 6. •

Reliability Energy :There are four way in which node consume energy Sensing Computation Storing 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.
