Simulating GAF in NS-2

Geographic Adaptive Fidelity (GAF) is a protocol that can be used along with other protocols such as AODV, DSR etc. 

Here I am providing steps to run GAF

One can look into the ../ns-2.35/tcl/test folder for already existing TCL files

GAF can run as follows

$ ns test-all-wireless-lan-gaf.tcl gaf

However this way doing can take very long time to complete the simulation. You may open the file and can change the simulation time to a small time (by default 800 seconds is the sim time). 

The simulation traces will be available in temp.rands file.

You can also add nam trace file as follows

set namtrace      [open $opt(tr).nam w]

$ns_ namtrace-all-wireless $namtrace $opt(x) $opt(y)

in TestSuite instproc init {} function

Once the simulation is completed, you can view the simulation through nam by typing the command as follows

nam temp.rands.nam
