Overview INTRODUCTION RECENT DEVELOPMENT WINS System Architecture WINS Node Architecture WINS Micro sensor WINS Digital Signal Processing WINS characteristics & application Design consideration Conclusion

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. This sensed signal is then converted into power spectral density and the compared with reference value of our convenience.

INTRODUCTION (WINS) 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.

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  multihop, self-assembled, wireless network algorithms for operating at micropower levels.

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. Continuous operation low duty cycle

WINS NODE ARCHITECTURE 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 interface signal processing for event detection control Processing event classification & identification wireless internet interface continuously vigilant operation low-duty cycle operation

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. Thermal Infrared Detector

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.

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. WINS micropower spectrum analyzer architecture

WINS characteristics & application 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

Application 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. On a local, enterprise scale, WINS will create a manufacturing information service for cost and quality control.

Design consideration Reliability Energy :There are four way in which node consume energy Sensing Computation Storing Communicating Sensing: Choosing right sensor for the 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. Enclosure

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 . 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.
