Wireless Sensor Network Perseiving Node And Information Accessing And Gathering Technology Reaserch

This thesis introduced in the current world the extremely popular low speed wireless sensor network., as well as one kind of wireless sensor network platform based on embedded system. Through invesgating the environment data to the survey and the information sensation way analysis and practicing, has profited from the domestic and foreign popular wireless sensors network agreement and the technology, has built the wireless sensor information sensation and the data gathering network platform.And completed one kind to embedded processor based on MSP430 the low power wireless sensor network design and the realization.This thesis first introduced the domestic and foreign wirelesssensors network research present situation, the wireless sensor network main research content and the essential technology, accumulate based on protection environment consideration our country carries out the wireless sensor network research and the necessity. Through the introduction of wireless sensor network related network technology, the sensor technology, inserts the type system and so on the essential technology, has analyzed the realization wireless sensor network feasibility. Then through above result comparison and the wireless sensor network characteristic, introduced one kind of wireless sensor network.The microprocessor is small, low power, low cost and high performance, widely applies to the industry control, wireless communication, network application,expense class electron, as well as domain and so on imagery andsecurity product. This thesis introduced based on AT89S52 microprocessor, the design wireless sensor network gatewaydesign and the sensor nodes.Finally the system has carried on the analysis and the summary regarding this, introduced powerpc embedded processor and embedded linux to transplant the embedded system. And introduced another plan based on the time sharing multiple address turned on under the distributional topology condition and continued work which had to do to make the analysis.
