The main goal of this thesis is to propose efficient adaptive communication mechanisms using cross layer interactions in IEEE 802.11 WLANs. First, we present a detailed performance evaluation of 802.11a/b PHY layer transmission modes. The second contribution of the thesis concerns 802.11 MAC/PHY layers modelling. An analytical model that accounts for the positions of stations with respect to the access point while evaluating the performance of 802.11 MAC layer, has been proposed. The third contribution of the thesis concerns rate adaptation mechanisms and especially cross layer algorithms between MAC and PHY layers. An adaptive rate selection algorithm, called AARF for low latency systems that improves upon ARF to provide both short-term an...
