Abstract
Wireless work is a new kind of meshwork with a big progress in micro-electronics, munications and embedded system -time supervise,
apperceive,gather and process data information of all supervision has all extensive
application foreground,and is highly recognized by the military field,the academia and the industrial field in many IEEE protocol with low cost and low power consuming has provided an international standard of munications for wireless work between sensor is constituted by physical layer and medium access control sub-layer of the IEEE ·2003 standard, work layer and application layer of the ZigBee is a wireless work operation system designed by the researchers in California University for the sensor nodes mica.
The wireless work based on IEEE is applied in the industry locale
device layer,for the purpose of solving problems of expensive disposing wire cost and weak anti-jamming ability while data is transmitting because the industry locale device layer adopts lineate the actual application of the paper,hardware research platform C51RF-3 and software develop platform IAR of wireless work based on IEEE
are sensor nodes need the support of operation system in applications,TinyOS port on the 2430 of C5 1RF-3 is providing an uniform international standard municating between sensor nodes,
munication protocol IEEE is implemented on the sensor node
based on the point of over loading status in TinyOS applications,TinyOS kernel schedule mechanism is analyzed clearly,and a kind of TinyOS task schedule algorithm based on time—limit priority is test indicate that data throughput of the sensor node and task real-time response are increased by adopting the TinyOS task schedule algorithm based on time-limit priority.
