Modeling of network delay variation in packet voice communications on mobile ad-hoc networks

摘要

The goal of this work is to model network delay processes of packet voice communications on mobile ad-hoc networks (MANETs). To do that, a wide range of representative and realistic scenarios of MANETs has been defined and simulated. The gathered delay traces are inspected in order to discover features that are used to propose a new Markovian model of network delay behavior processes over MANETs. Next, an efficient calibration process has been conducted through empirical network delay traces to find good model' characterization parameters. The Kolomogorov-Smirnov validation test proves that our model matches nicely the empirical trend of delay-variation processes over MANETs. Moreover, our analysis shows that our network delay-variation model achieves a good coarse-and subtle-grained behavior that matches well empirically observed ones.
