Design And Implementation Of Intelligent Community Wireless Sensor Network Node Based On CC2431

With the rapid development of embedded computer technology, sensor technology,wireless communication technology and information processing technology, wirelesssensor networks made great progress. Wireless sensor networks are multi hopself-organizing network, composed by a large number of sensor nodes, in the monitoredregion. This kind of networks not only collect and process the current data of detectedobjects but also send them to the observer, which widely apply in the military defense,industrial control, intelligent building, intelligent transportation, environmentalmonitoring, emergency rescue and disaster relief and other fields.Design and implementation of sensor node is one of the major problems in wirelesssensor network. On the basis of existing classical system of sensor nods, this study,according to this study requirments, designs an intelligent wireless sensor nodes. Tocomplete the code of the sensor modele, the study is processed by the circuit principlemap and PCB map of the corresponding, produced by CC243l (integrated CC2420RFand805l) from TI company, then welding and debugging node.And joint program,completed with the help of the TinyOS and TinyOS operating system on the basis ofassembly structure of NesC language. The research focus on the sensor nodes in theprogram control program and node low power applications. In addition, In order toremain the WSN’S sustainability, this network take advantage of the solarenergy.Therefore, the invented nodes in this study are of low consumption, low cost,frindly enviroment and sustainability.etc.
