Random Waypoint mobility model.

The node moves in line segments. For each line segment, a random destination position (distributed uniformly over the playground) 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 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.
