WINS provide a new monitoring & control capability for monitoring the border of the country.

Usig this concept we can easily identify a stranger or terrorist entering the border.

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 combines sensing, signal processing,decision capability, wireless networking capability in a compact, low power system.

On global scale WINS will permit monitoring of land, water & air resources for environment monitoring.

The border area is divided into number of nodes.Each node is in contact with each other &main node.

The noise produced by the footstep of the stranger is collected using the sensors.

This sensed signal is then converted into PSD & compared with reference value of our convenience.

Accordingly the compared value is processed using a microprocessor which sends appropriate signals to the main node.Thus the stranger is identified at the main node.

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

Support large number of sensors. These are also used in short distance

commnication (1KM). Internet acess to sensors, controls &

processor.

More reliable. Consumes more energy than other

systems. Resistant to all weather condition. Also used to monitor in environmental

conditions. More cheaper. Reasonably faster than other systems. Used in industries. Used in transportation system.

The network is self monitoring & secure. Now it is possible to secure the border

with an invisible wall of thousands /millions of tiny interconnected sensors.
