The paper presents a method of performance estimation of IEEE 802.11 wireless networks with linear topology using Markovian arrival processes (MAP) for traffic modelling and phase-type (PH) distributions for service time approximation. PH -distribution is reconstructed from the data obtained from the simulation measurements. Markov processes space reduction methods are used to overcome the state-space explosion problem appearing in large-scaled networks analysis. Both tasks of reconstructing PH -distribution and MAP reduction are defined as optimization problems. The performance of the proposed methods is illustrated with numerical examples.
