MAC IEEE802.11 CSMA/CA: A Simulative Performance Analysis

Abstract

In this paper we introduce an algorithm based analytical model to calculate the performance of the wireless LAN MAC protocol – known as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) – taking into consideration the random exponential back off algorithm. The effects of changing the load on medium utilization and average waiting time are demonstrated and result concluded for high medium and low load conditions.
