// This program configures a grid (default 5x5) 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.
//
//Network topology
//   |  200m  |---------800m----------|  200m  |
//

// the layout is affected by the parameters given to GridPositionAllocator;
// by default, GridWidth is 5 and numStaNodes is 25..
//
// 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-simple-adhoc-grid --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-simple-adhoc --distance=500"
// ./waf --run "wifi-simple-adhoc --distance=1000"
// ./waf --run "wifi-simple-adhoc --distance=1500"
// 
// The source node and sink node can be changed like this:
// 
// ./waf --run "wifi-simple-adhoc --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-simple-adhoc-grid --verbose=1"
//
// By default, trace file writing is off-- to enable it, try:
// ./waf --run "wifi-simple-adhoc-grid --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-simple-adhoc-grid-0-0.pcap -nn -tt
