Wireless Integrated Network Sensors

Abstract:

Wireless Integrated Network Sensors(WINS) provide a new monitoring and control capability for transportation, manufacturing, health care, environmental monitoring and safety and security. They combine sensing, signal processing, decision capability, andwireless networking capability in a compact, low power system. This paper covers important applications of WINS, Border Security. Using the concept of WINS 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 is collected using the sensor. This sensed signal is then converted into power spectral density and the 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. A series of interface, signal processing, and communication systems have been implemented in micro power CMOS circuits.

Introduction

Wireless Integrated Network Sensors (WINS) provide distributed network and Internet access to sensors, controls, and processors that are deeply embedded in equipment, facilities, and the environment. The WINS network is a new monitoring and control capability for applications in transportation, manufacturing, health care, environmental monitoring, and safety and security, border security. WINS combine micro sensor technology, low power signal processing, low power computation, and low power, low costwireless networking capability in a compact system. WINS networks provide sensing, local control, and embedded intelligent systems in structures, materials, and environments. Compact geometry and low cost allows WINS to be embedded and distributed at a small fraction of the cost of conventional wireline sensor and actuator systems. On a local, wide-area scale, battlefield situational awareness will provide personnel health monitoring and enhance security and efficiency. Also, on a metropolitan scale, new traffic, security, emergency, and disaster recovery services will be enabled by WINS. On a local, enterprise scale, WINS will create a manufacturing information service for cost and quality control. The opportunities for WINS depend on the development of scalable, low cost, sensor network architecture. This requires that sensor information be conveyed to the user at low bit rate with low power transceivers.
