Transient Field Of Wireless Sensor Networks, Key Technology Research

The wireless sensor network technology has been accelerated, with the rapid development of Wireless communication,Embedded Computer,Sensors,MEMS and Distributed Information Processing technology. WSN can be employed in applications such as military,national security,disaster prediction,traffic management,medical,environment,manufacturer and so on. It is foreseeable that the development of WSN will bring great changes to people's lives.Taking advantage of wireless sensor network, this article studies the topology,protocol and algorithm of WSN based on the review of the application status of transient data acquisition technology and wireless sensor network technology, in solving the problems of traditional transient data acquisition technology which uses wired collection in some applications.First, complete the overall design of wireless sensor network, according to the special requirement of the transient data acquisition, design the hardware of acquisition node and sink node, select the main components taking the low power consumption and anti-jamming performance into account.Second, complete the hardware design and debugging of the acquisition node and sink node, study the principle of the hardware depth.Moreover, complete the software development and debugging for wireless sensor network, including the design of data collection process,wireless transceiver program, synchronization trigger system,time synchronization program and sleeping program.Last, test the performance of wireless sensor network and design the node reliability.
