Abstract: Comparing with the wired networks, the guaranteed QoS is difficult to get in wireless networks, because of its limited bandwidth and variable channel. Network traffic prediction is important for network control and allocation. This paper presented a method. The deviation function of threshold value v was made by the method of variance analysis for wireless network traffic, which presented bases for selection threshold value. At last, according to the threshold crossing theory, the efficiency of the solution was validated through calculating the crossing intensity. The threshold value can implement better in predicting the traffic.

Key words: wireless network traffic, threshold value, derivation function, threshold crossing theory
