Analysis of a new delay enabled EDCF for voice transport over IEEE802.11e

A new subfunction for the IEEE 802.11e EDCF allowing efficient transport of real-time traffic is proposed. The delay induced by the freezout of the backoff counter is to be considered. Intentional dropping is used if a certain threshold delay is exceeded. A system enabled with this suggested feature is analyzed and the impact of backoff parameters on the transmission probability, the dropping probability, the transmission delay, in addition to the throughput will be evaluated. The required equations of the Markov chain will be derived, in addition to the equations for delay and throughput.
