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

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.
