N2 - 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.
