In this paper, the authors deal with the performance analysis of WLAN under variable number of nodes using the adjustable parameters such as TXOPLimit, CWmin, CWmax and AIFS in EDCA. The comparative analysis is done by varying the number of nodes and the adjustable Access Category (AC) parameters in the EDCA access mechanism. The throughput and delay parameters of the QoS are measured. The simulation is done using the Network Simulator 2.28 (NS) tool in RedHat Linux environment. The simulation results obtained gave a better performance improvement using the adjustable altered parameters in EDCA access method than the existing methods.
