An Analytical Model of Rate-Adaptive Wireless LAN and Its Simulative Verification
Overview Wireless Local Area Networks (WLAN) see increasing deployment in private and public environments; most of these being based on the IEEE 802.11 standard. The error prone nature of the wireless link and the probabilistic method to access the shared channel make it difficult to predict the user's performance. This is further complicated by rate adaptation, i.e. the dynamic adjustment of the modulation scheme to the characteristics of the wireless channel. Predicting Quality of Service (QoS) parameters, however, can help automizing mobile Internet access. An analytical model is developed of rate adaptive Wireless LAN, which is then enhanced by modeling traffic flows to randomly located users in the range of an access point.
