Abstract
Simulation scenarios using either the Random Waypoint mobility model or some flavors of Random Direction mobility models often exhibit speed distributions of their mobile entities that actually differ from the chosen speed distribution functions. Furthermore, this speed distribution may change over simulation time thus breaking the stationarity criteria. This report surveys the problem and contributes an adjusted model generating speed distribution function to obtain an observable uniform speed distribution.
