//
// Implements the Random Waypoint mobility model.
//
// The node moves in line segments. For each line segment, a random destination
// position (distributed uniformly over the constraint area or volume) and a
// random speed is chosen. You can define a speed as a variate from which a new
// value will be drawn for each line segment; it is customary to specify it as
// uniform(minSpeed, maxSpeed). When the node reaches the target position,
// it waits for the time waitTime which can also be defined as a variate.
// After this time the the algorithm calculates a new random position, etc.
//
// This model was originally written by Georg Lutz (GeorgLutz AT gmx DOT de) for
// his diploma thesis "Effizientes Modell fuer Funkverbindungen in 4G-Netzen fuer
// OMNeT++" (Efficient model for radio links in 4G networks for OMNeT++)
// at Institut fuer Telematik, Universitaet Karlsruhe (Institute for
// Telematics, University Karlsruhe, Germany), 2005-06-21.
