چکیده
This paper investigates the analytic performance of IEEE 802.11e enhanced distributed channel access (EDCA) under saturated traffic load. Compared with the existing analytical models of EDCA, we obtain transmission probability τi by applying the renewal theory and provide simple but accurate delay model for IEEE 802.11e EDCA by considering the possibility that a station’s backoff procedure may be suspended due to transmission from other stations, which is inherent to the difference of AIFS value. We derive several performance measures such as the probability generating function of HoL-delay(MAC delay) and throughput.

متن کاملThroughput Analysis Model for IEEE 802.11e EDCA with Multiple Access Categories
IEEE 802.11e standard has been specified to support differentiated quality of service (QoS), one of the critical issues on the conventional IEEE 802.11 wireless local area networks (WLANs). Enhanced Distributed Channel Access (EDCA) is the fundamental and mandatory contention-based channel access method of IEEE 802.11e, and delivers traffic based on differentiated Access Categories (ACs). A gen...
متن کاملA Novel Performance Evaluation Model for IEEE 802.11e EDCA
IEEE 802.11e Enhanced Distributed Channel Access (EDCA) is the most popular standard used in WLAN to support QoS for various real-time service flows. Based on DCF, EDCA introduces some new QoS parameters, which are defined by IEEE 802.11e standard. But how to adjust these parameters is still worth investigating. In the paper, we present a novel saturated throughput analysis of the IEEE 802.11e ...

The IEEE 802.11e standard has been introduced to support service differentiation for wireless local area networks. In wireless multi-hop networks, the performance of IEEE 802.11e EDCA has to confront with some practical problems such as unsaturation traffic and hidden node problem. Hence, this problem has attracted numerous studies in recent years, in which several investigations use analytic m...
