چکیده
Probably no protocol has been analyzed as much as the various versions of the IEEE 802.11 Distributed Coordination Function (DCF). In this paper, we show how to describe a typical DCF analytic model as a semi-Markov process (SMP). We do this at the hand of an example IEEE 802.11 network in Basic Access mode under both saturated and unsaturated traffic conditions. We show how to solve the corresponding SMP numerically. The accuracy of the technique is illustrated by comparing the results with that from the analytic model that is most frequently cited in the research literature.

Performance Analysis of IEEE 802.11 Non-Saturated DCF
In the IEEE 802.11MAC layer protocol, the basic access method is the Distributed Coordination Function which is based on the CSMA/CA. In this paper, we investigate the performance of IEEE 802.11 DCF in the non-saturation condition. We assume that there is a fixed number n of competing stations and packet arrival process to a station is a poisson process. We model IEEE 802.11 DCF in non-saturati...

Wireless communication always attracts extensive research interest, as it is a core part of modern communication technology. During my PhD study, I have focused on two research areas of wireless communication: IEEE 802.11 network performance analysis, and wireless cooperative retransmission. The first part of this thesis focuses on IEEE 802.11 network performance analysis. Since IEEE 802.11 tec...
متن کاملComparing the results from various performance models of IEEE 802.11g DCF
IEEE 802.11 DCF is the most widely-used CSMA/CA access control mechanism. Recent analytic performance models for DCF have received acclaim for both their simplicity and reported accuracy. Most of these models share the assumptions of full single-hop connectivity among all stations, that DCF back-off may be modeled as a Markov process and that the network is saturated with traffic. In order to v...
متن کاملAnalysis of Unsaturation Performance of IEEE 802.11 DCF with and without Slow Contention Window Decrease
Most of analytical models proposed so far for the IEEE 802.11 distributed coordination function (DCF) focus on saturation performance. In this paper, we develop an analytic model for unsaturation performance evaluation of the IEEE 802.11 DCF with and without slow contention window decrease (SCWD). The model explicitly takes into account the carrier sensing mechanism and an additional backoff in...
متن کاملPerformance Anomaly of the IEEE 802.11 DCF in Different Frame Error Rate Conditions
We propose an analytic model to compute the station’s saturated throughput and packet delay performance of the IEEE 802.11 DCF (Distributed Coordination Function) in which frame transmission error rates in the channel are different from each other. Our analytic model shows that a station experiencing worse frame error rates than the others suffers severe performance degradation below its deserv...
