Re: [ns] question on installation NS-2.29 on Linux Ubuntu

[Arturo Servin]

I had the same problems in Ubuntu 6.10 and ns-2-31. I had to compile
with gcc and g++   4.0 instead of 4.1 (default in my distro).

There are a couple of urls documenting this and how to install ns in
ubuntu.

[ns] how to computer the Transmission range

[Mohammed Abu Hajar]

Hi All,
   
Is there any utility in NS-2 that compute the transmission range of a wireless 
node like in glomosim simulator you type at the command line: radio_range 
config.in it's gives the range in m like 375m.
   
  Thanks

Re: [ns] routing over a fixed path in wireless ad-hoc network?

[Song Luo]

Basically, those protocols will find routes for packets automatically, and
you cannot determine in advance. But one method may work: you can enable
recvRequest function only at nodes you want the packets pass. In your
example, you only let node2, 3 and dest receive route requests and reply,
and let all other nodes discard requests without doing anything. I think it
should work for at least aodv and dsr, not sure for dsdv and tora.

[ns] utility of an associated DCH with HS-DSCH in Eurane?

[neila el héni]

Hi
I see that Eurane uses preprocessed Matlab files that contain, among others,
the CQI variations along several TTIs for each UE.

On the other hand, the DCHs  associated to the HS-DSCH are normally used in
order to report, to the Node B , the CQI and (N)ACK of the served UE.

So what is the utility of associating a DCH to the HS-DSCH in Eurane since
the CQI values are known before launching simulations (in the Matlab
files)???

Another question: do the input matlab trace files imply a continuous
transmission for all the simulated UEs, since a trace file contains
consecutive TTI and the associated SNR and CQIs?

Thank you for your answer

This doesn't seem to be a problem with ns-2 but Unix which Mac OS uses.
Basically, this error shows up when you don't have an X server (which is,
IIRC, actually called client in the X terminology) running.

So are you sure you're having an X server running? I don't know if that's
default on Mac OS, don't know too much about it.

Can you open any other GUI application from the shell you're trying to
start nam from? (like xterm?) If not, that would support my theory that
something with your Unix-MAC-GUI chain is broken...

I'm on Ubuntu 6.10 and ns-allinone-2.30. ns-2 refused to work properly
until I used GCC/G++ 4.0 (instead of 4.1) for compiling.

Dapper shouldn't come with 4.1 by default but I'd make sure you don't have
it installed anyway and possibly try recompiling using switches:

You've been reposting this identically at least twice. This is not going
to help you increase your chances in receiving a reply. One thing that
might help though is giving a complete output of the compiler errors
including line numbers and showing the relevant C++ code.
