In this paper a new delay-enabled EDCF for the transport of real-time traffic over an IEEE802.11e wireless LAN is proposed. The proposed technique will drop any packet belonging to a conversational class when a maximum queueing delay is reached. The packets belonging to an interactive or a background class are not dropped due to the queuing delay. The performance of this new technique is evaluated and compared to the the standard EDCF when serving various traffic classes. The effects of the backoff parameters and the traffic composition on the transmission probability, the dropping probability, the medium access delay, and the throughput is investigated. It is believed that such study is imperative for the design of a mapping function between an inherently QoS capable network such as UMTS, and an IEEE802.11 LAN.
