Mobility models are essential part of wireless network design. Simulation of user mobility scenarios is a tricky business due to the boundary behavior of simulated objects (people, vehicles, trains, etc.). In this paper we present the initial results of a user mobility simulation scenario for applications to broadband Internet access. We simulated a local train in a square area with straight tracks of random length. The train accelerates uniformly to a maximum velocity and decelerating uniformly to a stop at the end of the track. The track lengths, stop times and speeds are all uniformly distributed. The mobility at the boundaries is simulated simply by discarding a track that falls outside of the simulated area. By comparing this simple model to a mean-values model, we see that this method yields pretty accurate results. More complex models with real-life track shapes and acceleration/deceleration ramps can thus be derived from simple boundary models like proposed here. We used 3D OpenGL for visual simulation and uniform random sampling for model derivation.
