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.
