Abstract

A Dynamic Slot Allocation scheme, called as DSA, tocontrol packet delay in TDMA base station is presented inthis paper. DSA applies multi-queue architecture and usethe queue status of base station, corresponding to eachmobile host, as a feedback to determine the required datarate of hosts. Adaptive rate control, dynamics priority andmulti-queueing system are three pillars of DSA. In analysis,we illustrate how the proposed DSA controls the targetqueue dynamics. Then we investigate the relationshipbetween queue dynamics and packet delay. As a result, thepacket delay of each host is effectively controlled by theparameters. Simultaneously, the controlled target queuealleviates the buffer management of a base station. Thesimulation results show the well-controlled queuedynamics and delay of the proposed scheme, even under acondition of high traffic variation.
