摘要

提出了一种利用广义随机Petri网(GSPN)评估无线局域网(WLAN)平均延迟时间及其标准偏差(抖动)的方法。采用GSPN对无线局域网进行建模，并利用与GSPN模型相关的马尔可夫链推导出的方程计算无线局域网的平均延迟时间和抖动。将该方法应用于802.11e无线局域网延迟时间及其抖动的评估。结果表明，基于方程的计算值与仿真值吻合较好。

An evaluation method for delay time and its jitter of WLAN using a GSPN model

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.
