Could someone help me?? 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...

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

Re: [ns] routing over a fixed path in wireless ad-hoc network?
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. On 4/7/07, tdinhtoan [EMAIL PROTECTED] wrote: hi, I am simulating an ad-hoc wireless network. The nodes do not move (a kind of wireless mesh network). Thus for a given pair of source node and destination node, I determine the routing path between them in advanced. i.e. the routing path: src - node2 - node3 - dest. I establish an CBR flow (UDP flow) from the src to the dest, and would like to route the packets from the src to the dest over this fixed path. This is some kind of Static Routing. How can I do? Which routing agent I should use: DSDV, DSR, TORA, or AODV? Could anyone give me some examples or guides? Thank you very much. Sincerely, -toan. PS: I hope it can be done without modifying the ns2 source code.
