Abstract :
This paper proposes a method for evaluating mean delay time and its standard deviation (jitter) of wireless local area networks (WLAN) using Generalized Stochastic Petri Nets (GSPN). The WLAN is modeled using GSPN and the mean delay time and its jitter are calculated using equations derived from the Markov chain associated with the GSPN model. The method is applied to evaluate delay time and its jitter for 802.11e WLAN. The results reveal that the values calculated based on the equations agree well with the values obtained from simulations.
