* \brief Steady-state random waypoint mobility model.
*
* This model based on random waypoint mobility (RWM) model for case when
* speed, pause and position are uniformly distributed random variables.
* The difference is that the initial values of this parameters are not
* from uniform distribution but from stationary distribution of RWM model.
* The implementation of this model is 2D-specific and with nonzero nodes speeds.
* In the 3D ns-3 coordinate system, the momement occurs on the
* \f$ z=\overline{Z} \f$ plane, where \f$ \overline{Z} \f$ is a constant which
* can be configured using the Z attribute.
*
* Based on NS-2 implementation by Toilers Research Group -- Colorado
* School of Mines (http://toilers.mines.edu).
* The papers related to this code are:
* W. Navidi and T. Camp, Stationary Distributions for the Random
* Waypoint Mobility Model, IEEE Transactions on Mobile Computing,
* vol. 3, no. 1, pp. 99-108, January-March 2004.
* W. Navidi, T. Camp, and N. Bauer, Improving the Accuracy of
* Random Waypoint Simulations Through Steady-State Initialization,
* Proceedings of the 15th International Conference on Modeling and
* Simulation (MS '04), pp. 319-326, March 2004.
