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.
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 reasonably faster. On global scale wins will permit monitoring of land ,water and air resources for environment monitoring.
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 osWINS 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.
Internet sensing signal processing / event recognition wireless communication low power networking local area worldwide user
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. Continuous operation low duty cycle
1998:WINS NG developed by the authors contiguous sensing, signal processing for event detection, local control of actuators, event classification, communication at low power Event detection is contiguous micropower levels Event detected => alert process to identify the event Further processing?Alert remote user / neighboring node? Communication between WINS nodes sensor actuator signal processing for event detection control Processing event classification & identification wireless internet interface continuously vigilant operation low-duty cycle operation
WINS nodes are distributed at high density in an environment to be monitored. WINS node data is transferred over the asymmetric wireless link to an end user
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
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.
If a stranger enters the border, his foot-steps will generate harmonic signals. It can be detected as a characteristic feature in a signal power spectrum.Thus, a spectrum analyzer must be implemented in theWINS. The spectrum analyzer resolves theWINS input data into a low-resolution power spectrum. WINS micropower spectrum analyzer architecture
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.
Reliability Energy :There are four way in which node consume energy 1. Sensing 2. Computation 3. Storing 4. Communicating
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
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.
