<p>IEEE 802.11 [1]is the standard that has emerged as a prevailing technology for the wireless local area networks. It can be considered the wireless version of Ethernet, which supports best-effortservice. IEEE is developing a new standard called 802.11e to be able to provide quality of service (QoS) in WLANs. Two possible methods have been proposed in [3]in order to improve the performance of service differentiation in the MAC layer. They are called PCWA (Practical Contention Window Adjustment) and AIPM (Adaptive Initiative Polling Machine). In this thesis, I will analyse both methods and propose new ideas to improve their performance, simulating the ideas concerning PCWA. Simulations show better general performance, especially for highest priorities flows, although the behaviour of the lowest priority one is reduced.</p>
