Melina Maria Afonso, Nagaraj K. Vernekar . Finer Tuning Of QoS Mechanisms for Performance Enhancement of Wireless Networks. International Journal of Computer Applications. 67, 16 ( April 2013), 32-35. DOI=10.5120/11481-7134
WLAN is supported by almost all of the modern communication devices. These devices are largely used for communication of multimedia data including real time data. There is limited QoS support in WLANs, which will become an impediment in deploying multimedia applications. The important QoS metrics for multimedia applications are delay, jitter, loss, and throughput. There are different mechanisms and techniques for controlling these metrics. A lot of work has been carried out as far as loss and throughput is concerned. This paper focuses mainly on reducing the delay and jitter. A study of the various QoS support mechanisms for wireless networks is carried out and suggestions for improvement have been proposed particularly pertaining to the MAC parameters which will lead to a more precise and finer tuning of the already available mechanisms.
