Wireless Integrated Network Sensors (WINS) provide a monitoring and control capability that detects events and communicates with a main control node. They operate continuously at low power and use a combination of micro sensors, signal processing, and a wireless internet interface to recognize characteristic signals, such as footsteps, to identify intrusions. The architecture includes various components that ensure event detection and classification while managing potential issues like false alarms due to sensor malfunctions.

- 3. WHAT IsWINS? Wireless integrated network sensors (WINS)is a new monitoring and control capability for applications . Function:- The function of WINS is detect event and provides information to main (control)node. Working:- Wireless integrated network sensor sense the signal, process and provides response as signal. Ability :- Wireless Integrated Network Sensors (WINS) provide distributed network and Internet access to sensors, controls, and processors.
- 5. Continuous operation low duty cycle WINS architecture includes sensor , data converter, signal processor, and control functions. The micro power components operate continuously for event recognition , while the network interface operates at low duty cycle. sensor actuator signal processing for event detection control Processing event classification & identification wireless internet interface continuously vigilant operation low-duty cycle operation

- 7. WINS MICRO SENSORS… It captures the harmonic signals produced by the footsteps of the stranger entering in the border. Whole area is partitioned into hexagonal region. These signals are then converted into their PSD values and are then compared with the reference values set by the user. Packaging

- 10. WINS DSP… 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
- 12. Unanticipated Faulty Behavior… Node will detect false event when sensor board is overheated. Result may be undetectable if incorrectly download program and depleted energy level etc.
