[ns] TORA error, DSR/DSDV/AODV working
Hi all,
Sorry to be sending multiple emails to this list but I'm really
struggling with this. I managed to get DSR routing working by changing
the queue type as suggested by others to CMUPriQueue. However TORA
still won't work and I can't work out what is going wrong or find any
solutions on the net. The error is shown below, with the tcl further
down. There is no difference between this code and the other protocol
code except for changing the protocol type. I have even tried to
download TORA examples
(http://www-sop.inria.fr/maestro/personnel/Eitan.Altman/ns.htm) which
also don't work.
Any help is appreciated!
Michael.

[ns] DSR and TORA not working, DSDV/AODV work
Hi all, I have modified the wireless1.tcl example with some simple adjustments trying to get some examples working. I have managed to get DSDV and AODV working (although I'm unsure whether DSDV is routing correctly) and they can be viewed in iNSpect fine etc. However if I change the routing protocol to either DSR or TORA neither will successfully compile. The error is: $ ns test.tcl num_nodes is set 20 warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl INITIALIZE THE LIST xListHead Loading connection pattern... Loading scenario file... Starting Simulation... SORTING LISTS ...DONE! channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 Segmentation fault (core dumped) The TCL file is pretty much exactly the same as the wireless1.tcl example except instead of using a traffic generator I make 2 simple connections, and I have made my own 20 node, 500x500, 500s long movement file using the generator setdest. The tcl file is shown at the end of this email. All examples work fine and I cannot work out what's going wrong, anyone got suggestions? Or if anyone can email me a similar wireless setup (mobile nodes, some basic traffic, some random movement) that works with all the routing protocols that would be handy also. Thanks, Michael. P.S. To run the test.tcl you'll have to make the movement file yourself using setdest, just use settings node=20, size=500x500, simulation time = 500s. test.tcl # Copyright (c) 1999 Regents of the University of Southern California. # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.

[ns] iNSpect problems
Hi All, I'm trying to iNSpect with great difficulty. I am trying with either Cygwin or Windows (whichever will work!) but both are failing on me. I believe the Cygwin install is failing because it can't detect GTK+ 2.0 properly (even though I'm sure I've installed it via the cygwin setup.exe). With the Windows install I can't work out how to properly install GLUT and I also think it's having problems with GTK/GDK even though I followed the install notes in the documentation that came with iNSpect. Has anyone been able to successfully install iNSpect with cygwin and able to give me a brief rundown on what to do from a base cygwin install? Or is it possible to copy a compiled version of iNSpect onto my computer, in which case can someone send me a compiled version of it? OR can anyone suggest a different visualization tool for wireless ns-2 networks? Any help is appreciated as this is for my thesis and is pretty critical to get a good outcome. Thanks, Michael.
[ns] List of Wireless Routing Protocols in ns-2?
Hi All, I am just interested to know if anyone has a list of wireless routing protocols that have been implemented in ns-2, and locations where they can be downloaded from? Thanks, Michael.
Re: [ns] where can i download ns-2.27 ?
ftp://ftp.isi.edu/nsnam/ns-allinone-2.27.tar.gz Google is your friend. ftp://ftp.isi.edu/nsnam/ should have all the distributions I think.

Re: [ns] can you help me please
Hi,
That error means that you don't have nam install. Try the command with the
exec at the front and see if that works. I think nam comes with ns-2 but if
you don't have it yet it is downloadable at http://www.isi.edu/nsnam/nam/
