Abstract

The distributed coordination function (DCF) in the IEEE 802.11 standard for wireless LAN is based on the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) like medium access control protocol. This collision avoidance is implemented by means of backoff procedure, which uses a rotating window mechanism. This paper presents simulation studies along with the analytical approach towards the slot selection probabilities and backoff mechanism. The obtained simulations allow us to determine the effective throughput versus offered load for different values of the contention window parameter and the number of the contending stations. The choice of different CWmin and CWmax parameters are analyzed.
