The paper reports on-going work on enhancing the support provided to soft real-time traffic by the IEEE 802.11e protocol. The proposed solution is based on a mechanism, called a Contention Window Adapter (CWA), which dynamically change the contention window size of the different Access Categories (defined by the IEEE 802.11e standard) according to the workload conditions of the wireless network. The aim is achieving better throughput, delay and jitter figures for soft real-time traffic flows under heavy traffic conditions, i.e. when the offered workload approaches the available bandwidth. Preliminary results are presented, which show the potential of the proposed approach.
