Abstract EN
IEEE 802.11 WLAN utilizes a distributed function at its MAC layer, namely, DCF to access the wireless medium.
Due to its distributed nature, DCF is able to guarantee working stability in a wireless medium while maintaining the assembling and maintenance cost in a low level.
However, DCF is inefficient in dealing with real-time traffics due to its incapability on providing QoS.
IEEE 802.11e was introduced as a supplementary standard to cope with this problem.
This standard introduces an Enhanced Distributed Coordination Function (EDCF) that works based on diff-Serve model and can serve multiple classes of traffics (by using different prioritizations schemes).
With the emergence of new time-sensitive applications, EDCF has proved to be yet inefficient in dealing with these kinds of traffics because it could not provide network with well-differentiated QoS.
In this study, we propose a novel prioritization scheme to improve QoS level in IEEE 802.11e network.
In this scheme, we replace Uniform PDF with Gamma PDF, which has salient differentiating properties.
We investigate the suitability and superiority of this scheme on furnishing network with well-differentiated QoS using probabilistic analysis.
We strengthen our claims by extensive simulation runs.
