Research on Serial Port Bidirectional Transmission Technology of TelosB

TelosB is an embedded node which is usually used in wireless sensor network. It communicates with PC through the serial port. At present, most of communication between TelosB and PC are carried through the Cygwin window which is worked under the Tiny OS system. The data packet can not be used directly by the consumer because they are transmitted opaquely. We designed a serial port transmission technology based on TelosB node. Original data of TelosB can achieve bidirectional transmission under the VC++ serial program. Moreover, based on this technology, the improved serial transmission technology make consumer more conveniently and directly to use TelosB. The experiment result shows that every kinds of data packet are transferred fast and accurately with transparent form.
