Border security using Wireless Integrated Network Sensors(WINS)
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 à multihop, self-assembled, wireless network
algorithms for operating at micropower levels
• A general picture
• Distributed sensor at Border

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)
• Sensor board
• 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 energy
1. Sensing
2. Computation
3. Storing
4. 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.
• 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 .
