IOSR Journal of Computer Engineering (IOSR-JCE)Summary: The primary medium access control (MAC) technique of 802.11 (Wireless Local Area Networks) is called
distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance
(CSMA/CA) scheme with binary exponential backoff (BEB), where a node increases its contention window CW
upon every packet collision. The performance of an IEEE 802.11 network depends on the operation of this
backoff mechanism.
Therefore, the aim of this work is to analyze the performance of IEEE 802.11 DCF, which is done by both
analytical and simulation study. In the analytical study, MATHLAB is used to solve the equations numerically to
calculate the throughput, where the simulation study is conducted using NS-2 to measure the throughput. The
throughput is measured in the assumption of ideal channel conditions and a fixed number of nodes, each always
having a packet available for transmission (saturation conditions). The evaluation is done for both cases of
basic access and RTS/CTS mechanisms.
