WSN, change the world of new Technology
Traditional sensors is the progressive realization of miniaturization, intelligence, information, networking, and is going through a sensor from the traditional (DumbSensor) intelligent sensor (Smart Sensor) Embedded Web Sensors (Embedded WebSensor) have been constantly extensive development process.
As microelectromechanical systems (Micro-Electro-MechanismSystem, MEMS), System on Chip (SOC, Systemon Chip), wireless Communicate And low-power embedded technology, the rapid development of wireless sensor network (Wireless SensorNetworks, WSN) technology has emerged and its low-power, low cost, the characteristics of distributed and self-organization to bring a sense of information field change. This has become the new hot spot for all areas.
Wireless sensor networks is an interdisciplinary technology that is deployed in the monitoring area by the large number of low-cost micro sensor nodes, wireless communication through the formation of a multi-hop ad hoc networks. MEMS-based micro-sensor technology and wireless networking technology for wireless sensor networks given the broad application prospects. These potential applications can be summarized as: military, aviation, terrorism, explosion, disaster relief, environment, health, health care, Home , Industrial, commercial and other fields.
WSN will be one of the world's next four-tech industries, will trigger a wave of new industries.
1999 Business Week to the United States as the 21st century's 21 most influential one of the technologies; in 2003, Massachusetts Institute of Technology Comments on the report to predict the future technological development will change the world listed as top ten new technologies. President of the Council in the 21st Century "in federal Energy And development planning "in that industry wide application of wireless technology will enable the efficiency of industrial production increased by 10%, and 25% lower emissions of pollution.
WSN, Development and Planning Back in the 70's, the emergence of point to point transmission using traditional sensors, which constitute the connection sensing controller prototype wireless sensor networks, we have classified it as the first generation of wireless sensor networks.
Related disciplines with the continuous development and progress, sensor networks and also offers a comprehensive access to a variety of information signal processing capabilities, and through associated with the sensor controller, there is information on the composition of the synthesis and processing capabilities sensor network, this is the second generation of sensor networks.
Starting from the end of the century, fieldbus technology has begun to apply sensor networks, intelligent people to use its established network, a large number of multi-function sensors are used, and use wireless technology to connect, wireless sensor networks evolved. Wireless sensor networks are a new generation of sensor networks, has a very wide application, its development and application, will be to human life and production of far-reaching implications in various fields. Developed countries like the United States attaches great importance to the development of wireless sensor networks.
1995 U.S. Department of Transportation proposed the "National Intelligent Transportation System Project Planning ", is expected to be fully operational by 2025. The program tried to effective integration of advanced information technology, data communications technology, sensor technology, control technology and computer processing technology, and applied to the entire surface traffic management, the establishment of a wide range of comprehensive comprehensive real-time high Transportation Management system. The new system will effectively use the sensor network traffic management.
U.S. Army in 2001 proposed the "smart sensor network communication" program approved for implementation in the 2001-2005 fiscal year. The basic idea is: in the field laid a large number of sensors to collect and transmit information, and relevant raw data filtering, and then send that important message to the data fusion center, the large amount of information integration is a panoramic view of the battlefield Fig. When the combatants may be distributed to them when necessary, to the perception of the battlefield situation greatly improved.
2002 5 months, the U.S. Department of Energy Sandia National Laboratory in cooperation with the U.S. to jointly study found that as soon as possible to subway stations and other places as the target of chemical and biological weapons attacks, and to take timely Prevention Countermeasures systems. It belongs to the United States Department of Energy terrorist measures an important part of the project. The system is set Detect Toxic gas chemical sensors and network technology in one.
