Abstract :
ACKS (ACK skipping) is a mechanism to enable QoS support in standard IEEE 802.11 WLANs working in infrastructure configuration. The paper presents an analytical model to estimate ACKS performance under saturation conditions, when multiple service classes are considered. Based on this model, the paper proposes an algorithm that optimally configures ACKS networks to provide QoS guarantees for DiffServ-like configurations, that is, for three classes of stations characterized by different QoS requirements. The effectiveness of the proposed algorithm is proved by simulation in different network scenarios.
