Design And Implementation Of Sink Nodes In Wireless Seneor Network

The wireless sensor network is a new type of data acquisition and processing technologycan be widely applied to environmental monitoring, health, agricultural development andother fields. At present, caused a high degree of attention at home and abroad.Aggregation node is the most important part of one of the wireless sensor network, itcollected each sensor node to the data integration, and served as the responsibility tocommunicate with the outside world. The aggregation node in this article for embeddedLinux systems.This project is to rely on the perception of agriculture-related technology SunlightGreenhouses wireless monitoring system. Wireless sensor network technology, thedetection area of the greenhouse monitoring. The use of wireless sensor networks tocollect temperature, humidity, light intensity, soil composition and other data, combinedwith the role of these factors on plant growth, to reduce consumption in agriculturalproduction costs, and increase crop yield.The contents of this paper are mainly the following according to the needs of the sinknode, the idea of embedded systems development, as well as the characteristics of theapplication of wireless sensor networks, the sink node overall design.Aggregation nodehardware module selection, aggregation node design through the analysis of the varioushardware modules, hardware platform, provides a strong support for the subsequentdevelopment.Focus on the principle of the U-Boot software and embedded Linuxoperating system on this basis, to solve the U-Boot and embedded Linux operatingsystem how to transplant a new hardware platform. Ultimately, success in self-developedhardware platform to be realized.Simple conversion function of the aggregation nodeprotocol stack in the embedded Linux system.
