Abstract

The paper proposes a feedback based dynamic scheduler (FBDS) to allocate the first-hop bandwidth in IEEE 802.11e using HCF (hybrid coordination function) controlled channel access. Properties of the proposed control algorithm are investigated, theoretically and using ns-2 simulations. The obtained results show that the proposed FBDS algorithm succeeds in guaranteeing the delay bounds required by audio/video applications in the presence of a very broad set of traffic conditions and network loads.
