A study on improving reliability of 920 MHz-band wireless networks using advanced source routing function

摘要

To improve the reliability of communication that becomes a problem when economical 920 MHz-band wireless networks are used for control and sensing applications, we investigate the introduction of source routing method into wireless nodes. In particular, higher real time property and reliability of communication are required in wireless control networks. We developed a source routing program for small scale networks consisting of 20 to 30 terminals, and conducted an experiment with wireless units implemented the source routing program. As a result of the experiment, we showed that the reliability of wireless communication can be improved by using source routing.
