—In an infrastructure based wireless network, access
point (AP) is the central authority which controls all the
registered nodes and relaying traffic in the network. Even
though all traffic is routed through AP, the open nature of the
underlying medium is prone to environmental factors, etc.
which degrade the performance of the overall network.
However, in a saturated case the AP becomes the bone of
contention among nodes which can result in collisions, packet
In this study, authors analyze the performance of 802.11
WLANs that utilizes the Distributed Coordination Function
(DCF). A simulation study having contending stations within
the transmission range of an AP in a saturated environment are
considered, in view of varying data rates and packet sizes in an
error free environment. Simulation results are presented and
analyzed in the end.
