Modified EDCAAppraoch to Improve Quality of Service in WLAN



In this paper, we have proposed modified Enhanced Distributed Coordination Access (EDCA) in order to improve Quality of Service in Wireless LAN. In this approach, we have changed the Contention Window (CW) for backoff procedure and method for calculation of Arbitration Inter Frame Spacing (AIFS). The proposed approach is implemented in Qualnet 5.2 Simulator and compared the results withconventional EDCA. The simulation shows that Modified EDCA produces less average jitter, less average end to end delay and improvements in throughput as compared to conventional EDCA mechanism.
