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