A way to find out, how to do the simulation ... start with these commands:
cd ns-allinone-2.26/ns-2.26/drandTcl/
( Or whereever you have the drandTcl/ folder )
./ns-drand simple-wireless.tcl 2 wirelessOpt.tcl
And / or : ./ns-drand simple-wireless.tcl 3 wirelessOpt.tcl
( 'ns-drand' is a backup copy of ns from the DRAND patched ns-2.26 )

Code:

[knudfl@localhost drandTcl]$ ./ns-drand simple-wireless.tcl 3 wirelessOpt.tcl

An empty file simple.tr is created, but now you have somthing, that you can work on.

.

A better result with more nodes : A trace file with content.
$ ./ns-drand simple-wireless.tcl 12 wirelessOpt.tcl
$ ./ns-drand simple-wireless.tcl 20 wirelessOpt.tcl
.. So with more nodes you can get a result to analyze.

.

See post #46 : 'ns-drand' is a backup copy of ns from the DRAND patched ns-2.26.

Just make a copy of the right 'ns' to /usr/local/ns-allinone-2.26/ns-2.26/drandTcl/
... then you can use ./ns simple-wireless.tcl 12 wirelessOpt.tcl

Note 1.
The reason for a special name for each version of 'ns' is for recognition.
When you have different versions of ns, the most easy way to avoid them
from getting mixed up, is to give the executables new names.
And one period ( . or ./ ) means 'the current directory'.
So when you see a ./ns, it means that is must be in the working directory,
in this case drandTcl/
( ns-something can also be a symlink to ns-allinone-2.26/ns-2.26/ns )

Note 2.
Do not use a low figure like 3 for the number of nodes.
2..3 : No result in "simple.tr". 12..20 or whatever : A usable "simple.tr" file.

Looks like an ns-2.26 modified for ZMAC ?

so this is the source of this error????


would i again build DRAND only in???
trying..

thank yoy very much.....both z-mac and DRand done!!!!!!!!!!!:-),,,after so much hard work....and yess @knudfl not without your help....

Starting Simulation...
(null) - invalid packet type (undefined).
...and empty simple.tr.....
help!!!

Don't know what's happening.

The instruction are quite clear. DRAND Ubuntu 10.10 summary :
tar xvf ns-allinone-2.26.tar.gz && patch -p0 < ns-2.26-gcc410.patch
cd ns-allinone-2.26/ns-2.26/ && tar xvf drandNS2.tar.gz
Then copy ( cp -a <file> <destination> ) the new files
ns-packet.tcl packet.h mac-802_11.cc cmu-trace.cc to their destinations.
And the new Makefile.in : cp -a drand-Makefile.in.txt Makefile.in
cd ../ && export CC=gcc41 CXX=g++41 && ./install

Alternatively use a binary "ns-drand" :
ns-drand-226_usr_local.i686.tar.gz ( 1.1 MB ).
( Usable when a /usr/local/ns-allinone-2.26/ is present.)

... And my DRAND "validate" in Ubuntu 10.10 , 32bits OS.
This is an expected OK result.

thanks @knudfl...yess your file works....:-)...thanks
