Quality of service (QoS) is an important issue to wireless LANs. In this paper, we study FARIMA model-based modeling and prediction in WiFi because FARIMA models have an ability to capture both the long and short-range dependent characteristics of traffic in wireless networks. The performance of the proposed FARIMA models is tested with four real traffic traces. Our experiments show that one-step forecasts based on the FARIMA models are better than those based on ARIMA models. We also propose a prediction-based admission control algorithm for WiFi networks using the FARIMA model. The experimental results show that controlled-load service consistently allows the network to achieve higher utilization than guaranteed service does
