Wireless Integrated Network Sensors (WINS) : A Border security solution Prepared By.... Deepak Kumar Mohapatra Pijush Kumar Banerjee OVERVIEW… WINS Introduction Evolution Working Principle System Architecture Node Architecture Micro sensor Digital Signal Processing Spectrum Analysis Characteristics applications Reference Conclusion ABSRACT… Provides a new monitoring for the borders of the country. Easy identification of strangers or some terrorists entering the border area. Border area is partitioned into no. of mutually connected nodes. Noise detection, Image processing, Biometric scanning, Thermal detection, Density comparison, AV modulation etc. are the main key roles. INTRO… WIRE LESS INTEGRATED NETWORK SENSOR (WINS). Require a few microwatt of power to operate, so it is cheaper than the conventional radar system. It produce a less amount delay to detect the target and reasonably faster. Evolution Of WINS… WINS Initiated in 1993 under Defence advance research project agency (DARPA) in US. LWIM (Low power wireless integrated micro sensor) program began in 1995. In 1998, WINS introduced for wide variety of applications such as multihop, self-assembled, wireless network algorithms for operating at micropower levels. Distributed sensor at Border… Working Principle… 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 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 se
