METHOD FOR DETERMINING LINK QUALITY IN WIRELESS NETWORK SYSTEM

摘要

The present invention relates to a link quality determining method in a wireless network system, which is able to determine network link quality between a master station and slave stations in the wireless network system having a synchronous super frame structure. The method comprises: a step of determining whether a current station is a master or a slave; a step of comparing a maximum time value, which does not require a packet exchange with a master after a slave accesses a network, with a time value of receiving a recent packet from slaves when the current station is a master as the result of the determination; and a step of determining link quality between a slave and a master in accordance with the result of the comparison.
