چکیده
The paper presents a new analytical saturation throughput model of IEEE 802.11 DCF (Distributed Coordination Function) with basic access in adhoc mode. The model takes into account freezing of the backoff timer when a station senses a busy channel. It is shown that taking into account this feature of DCF is important in modeling saturation throughput – yields more accurate results than models known from literature. The proposed analytical model also takes into account the effect of transmission errors.

متن کاملImproving WLAN Performance by Modifying an IEEE 802.11 Protocol
One of the limitations of the IEEE 802.11 distributed coordination function (DCF) protocol is its low bandwidth utilization under medium-to-high traffic loads resulting in low throughput and high packet delay. To overcome performance problems, traditional IEEE 802.11 DCF (“DCF”) protocol is modified to the buffer unit multiple access (BUMA) protocol. The BUMA protocol achieves a better system p...

IEEE 802.11 is the most important standard for wireless local area networks (WLANS). This paper presents a performance evaluation of IEEE 802.11 Distributed Coordination Function (DCF) in a multi-rate WLAN. We studied how throughput and delay varies with the distance of transmission in a multi-rate WLAN and the result was used to compare that of single rate WLAN. From the analysis it was observ...
متن کاملPerformance evaluation of collision avoidance schemes in ad hoc networks
IEEE 802.11 DCF (Distributed Coordination Function) is a popular protocol used for the physical and MAC layers in most ad hoc networks. DCF employs carrier sense multiple access with collision avoidance (CSMA/CA) and a binary slotted exponential backoff. It has been observed that the hidden and exposed terminal problems among stations are responsible for DCF’s performance-degradation. The issue...
