2.  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.

5.  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.

8.  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

9.  Support large number of sensors.  These are also used in short distance commnication (1KM).  Internet acess to sensors, controls & processor.

10.  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.

11.  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.
