Quality of Service Provisioning with modified IEEE 802.11 MAC Protocol

There has been a phenomenal increase in the demand of quality-of-service (QoS) in wireless networks over the years due to rapid growth in the number of wireless and mobile devices. Such devices are in use to access Internet and QoS aware applications such as video conferencing, voice-over IP, interactive video-on-demand and many other multimedia applications. wireless local area networks (WLANs) confirming to the IEEE 802.11 standard have become extremely popular at an unprecedented rate. As a result, WLAN networks are gaining the momentum and making their way into residential, commercial, industrial and public areas. These trends are more and more accelerated in places like airports, hotels and coffee shop, this typically has many floating end users. The time stringent applications are delay sensitive that require throughput and delay bound creates an urgent need for QoS support in WLANs
