+/**
+ * \brief a 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.
+ *
+ * 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.
