INTRODUCTION  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.

INTRODUCTION(CONT.)  This sensed signal is then converted into power spectral density and the compare with reference value of our convenience. 

§ 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 System Architecture 

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.

WINS NODE ARCHITECTURE

§ The WINS node architecture is developed to enable continuous sensing, event detection, and event identification at low power. § Lower power reliable & efficient network is obtained  with intelegent sensor nodes that include sensor signal  processing control wireless interface.

WINS NODE ARCHITECTURE(CONT.)  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 

WINS MICRO SENSORS  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. 

WINS DIGITAL SIGNAL PROCESSING § 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 the WINS.  The spectrum analyzer resolves the WINS input data into a low-resolution power spectrum. 
