Effect of Transmission Opportunity Limit on Transmission Time Modeling in 802.11e

Several analytical models have been developed for both 802.11 Distributed Coordinated Function (DCF) and 802.11e Enhanced Distributed Channel Access (EDCA). However, none of these models considers the 802.11e Contention Free Burst (CFB) mode which allows a given station to transmit more than one frame for each access to the channel. In order to develop a new and complete analytical model including all the differentiation parameters and able to be applied to all network conditions, we first need to know the time occupied by the transmission of a flow belonging to a given AC. The main objective of the current work is to analyze the TXOP bursting procedure and to propose a simple model allowing us to calculate the transmission time occupied by a particular AC when using the CFB mode. CFB performance analysis as well as the proposed model are discussed, demonstrated and validated by means of simulations.
