21 * Example program using a ns-2-formatted mobility trace generated
22 * by the BonnMotion mobility framework.
23 *
24 * With the provided tracefile (bonnmotion.ns_movements), the movements of
25 * one node are simulated for 1000 seconds. There are a few other files
26 * that provide metadata about the mobility:
27 * - src/mobility/examples/bonnmotion.ns_params
28 * - src/mobility/examples/bonnmotion.params
29 *
30 * These files are documented in the BonnMotion documentation.
31 *
32 * It is important to remember that the trace file dictates how many nodes
33 * (in this case, one) and how long (in this case, 1000 seconds) that the
34 * ns-3 program should use. If you want to change the mobility pattern,
35 * number of nodes, or duration, you need to use BonnMotion or another
36 * tool to generate a new trace.
37 *
38 * Finally, note that you can visualize this program using the pyviz
39 * visualizer:
40 * ./ns3 run bonnmotion-ns2-example --vis
