In this paper we compare and enhance the three prevailing approaches of IEEE 802.11e Performance analysis. Specifically, the first model utilizes a Markov Chain to describe the state of the Backoff Counter, the second is based on a general probabilistic explanation of the standard and the third forms a queuing network. We have injected, in the proposed models, new ideas to cover the latest update of the QoS-enabled 802.11e standard, and compared all the models showing results regarding the accuracy of each approach. Throughput performance is given for various parameters of the medium while including Gaussian error-prone channel in 802.11b/e. Results are also provided regarding the effect of the Block-ACK feature. The comparison is performed both in terms of accuracy and structural possibilities and finally the results are validated via simulations with Opnet Modeler. The proposed comparison mathematical analysis can also be extended to other applications and wireless protocols.
