Abstract:
    The invention relates to a bandwidth preformed medium access control method of wireless personal network, wherein it comprises that: first, central node receives the request from the service quality demand node, distributes the expanded transmission time slit, and adds the distribution information into signal frame, and sends the slit distributing command frame at the start of time slit; if the received signal frame contains the distributed time slit, the node receives the distributing command frame at the start of time slit; receiving all nodes of distributing command frame, dividing the transmission time slit into several slit groups, and bidirectional or one-way transmitting the sub time slit of each group when central node transfers. The invention can reduce transmission time delay, to save more energy, when it has same throughout and time delay property with IEEE802.15.4-2006 GTS transmission.
