Sensor networks are also included. It can be expected, a wide range of wireless sensor networks is an inevitable trend, it appears to the human society will bring great change. 
Although wireless sensor network application status of large-scale commercial applications, due to technical and other constraints still some way off, but in recent years, with the decline in the cost calculation and the microprocessor becomes smaller and has a large number of wireless sensor network was put into use. The application of wireless sensor networks mainly focused on the following areas: 
An environmental monitoring and protection of the environment as people increasingly high degree of concern, need to collect environmental data more and more, the emergence of wireless sensor networks for the randomness of the data acquisition provides a convenient, and can also traditional data collection methods to avoid environmental damage caused by invasive. For example, Intel's research labs researchers had 32 small sensors connected to the Internet, and to read the Maine "big duck island" on the climate, to evaluate a petrel nests conditions. Wireless sensor networks can also track the migration of birds and insects to study the impact of environmental change on crops, monitoring ocean, atmosphere and soil ingredients. In addition, it can also be applied in fine agriculture, to monitor pests in crops, soil pH and fertilization conditions. 
2 Medical Care Wireless Sensor Networks in medical research, care field can also show its mettle. Scientists at the University of Rochester using wireless sensor creates an intelligent medical room, the use of dust to measure an important sign of the occupants (blood pressure, pulse and respiration), 24 hours a day sleeping posture and status of activities. Intel also introduced a wireless sensor network home care technologies. The technique is discussed as a response to an aging society technology projects Center for Aging Services Technologies (CAST) is a part of the development. The system in the shoes, furniture and household appliances and other home with props and equipment embedded semiconductor sensors to help elderly people, Alzheimer's patients and families living with disabilities. Each sensor using wireless communication network will pass the necessary information can be efficiently so as to facilitate receiving care. But also can reduce the burden on caregivers. Intel's director of preventive health insurance research director Eric Dishman says, "In developing the technical aspects of nursing home use, wireless sensor network is a very promising field." 
Three military field as wireless sensor networks have intensive, random distribution of features, making it ideally suited for harsh battlefield environments, making it ideally suited for harsh battlefield environments, including enemy reconnaissance, surveillance troops, equipment and supplies determine the biochemical attacks, and many other purposes. U.S. Defense Advanced Research Bureau plans invest millions of dollars to help the University "smart dust" sensor technology research and development. Haber, president of research Allmendinger Forecast: smart dust sensors and related technology sales in 2004 from $ 10 million in 2010 to several billion dollars.
