The Research And Implementation Of Wireless Sensor Network

Wireless sensor network (WSN) is a distributed network system compose of a large amount of micro-sensors,which are distributed in the area to be monitored and organized by themselves.It includes the sensor technology,embedded technology,wireless networks communication technology,and can be able to monitor,appereceive and collect the information of the environment or monitoring objects real-timely.This paper comes up with a wireless solution based on wireless sensors networks,which is contraposing to the traits of group physiological parameters acquisition in group physiological parameters acquisition.This solution implements the parameters acquisition,at the same time it fixes the problems in traditional wired solutions effectively.Firstly,deficiencies of traditional wired solutions and advantages of wireless solutions which are used in parameters acquisition are analyzed in this paper.Then a wireless solution based on the Wireless sensor network is brought up,also the feasibility of the solution and the structure of the system are analyzed. After that,I modify and implement the LEACH protocol,which used in the Hierarchically Topographical Structure。Afterward,the embedded operating system, TinyOS,used in this design and node drive designed by NesC language are discussed in detail.Finally the test and analyze about the energy consumption of this system are been done.
