+// This program configures a grid of nodes on an
+// 802.11b physical layer, with
+// 802.11b NICs in adhoc mode, and by default, sends one packet of 1000
+// (application) bytes to node 1.
+//
+// The default layout is like this, on a 2-D grid.
+//
+// n24 (monitor node)
+//
+// n18 n19 n20 n21 n22 n23
+// n12 n13 n14 n15 n16 n17
+// n6 n7 n8 n9 n10 n11
+// n0 n1 n2 n3 n4 n5
+//
+// The lone Monitor Mode node receives all the packets passing by it
+// while the other nodes talk to each other.
+//
+// There are a number of command-line options available to control
+// the default behavior. The list of available command-line options
+// can be listed with the following command:
+// ./waf --run "wifi-monitor-mac --help"
+//
+// Note that all ns-3 attributes (not just the ones exposed in the below
+// script) can be changed at command line; see the ns-3 documentation.
+//
+// For instance, for this configuration, the physical layer will
+// stop successfully receiving packets when distance increases beyond
+// the default of 500m.
+// To see this effect, try running:
+//
+// ./waf --run "wifi-monitor-mac --distance=500"
+// ./waf --run "wifi-monitor-mac --distance=1000"
+// ./waf --run "wifi-monitor-mac --distance=1500"
+//
+// The source node and sink node can be changed like this:
+//
+// ./waf --run "wifi-monitor-mac --sourceNode=20 --sinkNode=10"
+//
+// This script can also be helpful to put the Wifi layer into verbose
+// logging mode; this command will turn on all wifi logging:
+//
+// ./waf --run "wifi-monitor-mac --verbose=1"
+//
+// By default, trace file writing is off-- to enable it, try:
+// ./waf --run "wifi-monitor-mac --tracing=1"
+//
+// When you are done tracing, you will notice many pcap trace files
+// in your directory. If you have tcpdump installed, you can try this:
+//
+// tcpdump -r wifi-monitor-mac-0-0.pcap -nn -tt
