Prioritization scheme for QoS in IEEE 802.11e WLAN

The exponential growth in demand for multimedia applications in wireless network has resulted in dramatic increased in different devices and connections accessing information. Indeed, this is primarily due to the fact that wireless and multimedia applications have been used quite extensively in business, commercial and communication industry. Supporting multimedia application in wireless environment with different bandwidth and delay requirement is challenging – this can eventually have detrimental impact on the system performance if the necessary quality of service (QoS) requirement has not been provided. This paper presents an approach which prioritizes the application base on its content in order to ultimately support and provide the needed requirements for multimedia application over wireless LAN. Consequently, the throughput of the IEEE 802.11e while maintaining its QoS requirement. The scheme has been simulated using NS2 simulator.
