A simulation study of an IEEE 802.11b which is the most important standard for
wireless local area networks was presented in this paper. The simulation is conducted using
OPNET IT Guru Academic Edition 9.1. Wireless network performance depends mainly on
the end to end throughput and average delay. Different applications place different
requirements on the network. Thus, it is necessary to evaluate and analysis the performance
of IEEE 802.11b WLAN system under the fundamental access mechanism for medium
access control (MAC) called distributed coordination function (DCF).This can achieve by
studying the impact of parameters such as Request to Send/ Clear to Send (RTS/CTS),
Fragmentation Threshold (FTS) and discuss the best configurations and parameters value in
correspondence to network load and topology to get best performance which is the main
objective of this paper.
