32 * This example program allows one to run ns-3 DSDV, AODV, or OLSR under
33 * a typical random waypoint mobility model.
34 *
35 * By default, the simulation runs for 200 simulated seconds, of which
36 * the first 50 are used for start-up time. The number of nodes is 50.
37 * Nodes move according to RandomWaypointMobilityModel with a speed of
38 * 20 m/s and no pause time within a 300x1500 m region. The WiFi is
39 * in ad hoc mode with a 2 Mb/s rate (802.11b) and a Friis loss model.
40 * The transmit power is set to 7.5 dBm.
41 *
42 * It is possible to change the mobility and density of the network by
43 * directly modifying the speed and the number of nodes. It is also
44 * possible to change the characteristics of the network by changing
45 * the transmit power (as power increases, the impact of mobility
46 * decreases and the effective density increases).
47 *
48 * By default, OLSR is used, but specifying a value of 2 for the protocol
49 * will cause AODV to be used, and specifying a value of 3 will cause
50 * DSDV to be used.
51 *
52 * By default, there are 10 source/sink data pairs sending UDP data
53 * at an application rate of 2.048 Kb/s each. This is typically done
54 * at a rate of 4 64-byte packets per second. Application data is
55 * started at a random time between 50 and 51 seconds and continues
56 * to the end of the simulation.
57 *
58 * The program outputs a few items:
59 * - packet receptions are notified to stdout such as:
60 * <timestamp> <node-id> received one packet from <src-address>
61 * - each second, the data reception statistics are tabulated and output
62 * to a comma-separated value (csv) file
63 * - some tracing and flow monitor configuration that used to work is
64 * left commented inline in the program
