Closed-form Solution of the Bianchi Model for 802.11 DCF and IEEE 802.11e EDCA
نویسندگان
چکیده
Based on some empirical observations, we present a fairly accurate assumption about the throughput performance under non-saturation conditions and when the system is near saturation. This allows us to find a closed form solution for the transmission probabilities and collision probabilities. These can be inserted into performance expressions derived from any available analytical model for 802.11e EDCA or 802.11 DCF. Here, we use the delay expression of one selected model for 802.11e EDCA, and observe that the closed-form solution of the delay matches well with the numerical calculations given by the model.

The next deployments of IEEE 802.11 WLAN will involve the coexistence of the legacy best effort stations and the new recently standardised QoS-aware stations in QoS Basic Service Set (QBSS). However, if no control is applied to the legacy stations, this coexistence may deteriorate QoS support provided by the new IEEE 802.11e standard. In this paper the influence of IEEE 802.11b DCF stations on ...

802.11b The legacy IEEE 801.11 doesn’t support QoS streams with priorities. It since causes some QoS demanding applications such as VoIP, Video streaming to be limited in its usefulness. Enhancements have been made to the MAC layer by the new 802.11e standard to support prioritized and parameterized QoS. The work of this paper is to simulate the new scheme and modify the existing OPNET WLAN MAC...
