Abstract
The present distributed scheduling architecture comprise a hierarchy of schedulers comprising one master scheduler and many slave schedulers. The master scheduler is located at the AP. Its basic role is to allocate physical bandwidth to the different terminals. The slave scheduler is located in the data link control layer of a wireless terminal and one is located in the AP. It is important to note that at the AP, both master scheduler and slave scheduler (AP) co-exist while at the wireless terminals only slave schedulers (WT) are implemented. The rationale behind this architecture, is that the AP allocates time slots to the wireless terminals based on the information it receives through the reservation protocol, however, to cope with the problem of this information being out of date, the wireless terminals are allowed to freely distribute the allocated slots among their connections.
