Performance Study of IEEE 802.11 DCF and IEEE 802.11e EDCA
One of the key factors for the wide acceptance and deployment of IEEE 802.11 Wireless Local Area Networks (WLANs) is the simplicity and robustness of the Medium Access Control (MAC) protocol. Based on the well-known carrier sense paradigm, with an exponential backoff mechanism devised to minimize the probability of simultaneous transmission attempts by multiple stations, the protocol is able to...
متن کاملAnalytical Modeling of the IEEE 802.11e EDCA Network
Contention Free Burst (CFB) is a promising burst transmission scheme defined in the IEEE 802.11e Medium Access Control (MAC) protocol to achieve differentiated Quality of Service (QoS) and improve the utilization of the wireless scarce bandwidth. Although modeling and performance analysis of the IEEE 802.11e network have attracted tremendous research efforts from both the academia and industry,...
متن کاملModeling the IEEE 802.11e EDCA for MAC parameter optimization
A model of the IEEE 802.11e EDCA function is presented. The model is built to be simple, but providing a clear description of the inter-relations between the EDCA MAC parameters (AIFS, CWmin, CWmax and TXOP values) and the traffic flow characteristics (packet arrival rate and packet length). The model is intended to be used as an abstraction of the IEEE 802.11e MAC protocol in WLAN flow level s...
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 ...
متن کاملPerformance Analysis of IEEE 802.11e EDCA in Non-saturation Condition
We focus on performance analysis of IEEE 802.11e EDCA in non-saturation condition. There have not been many analytic works in non-saturation condition due to mainly analytic complexity of models. However, non-saturation is valid in most real WLAN network. In this paper, we deal with the non-saturation case that the flow is not generated during which the previous flow is in service and flow size...
