[ns] R: RTSThreshold in Simulations
Alicia, RTS/CTS is used when frame size is greater than the RTS threshold. So you should act on the RTS threshold value to set RTS/CTS on or off. Marco Messaggio originale Da: [EMAIL PROTECTED] Data: 3-lug-2006 1.31 PM A: ns-users@ISI.EDU Ogg: [ns] RTSThreshold in Simulations Hello guys: I wonder if you activate the RTS/CTS in simulations for MANET. Does it depend on the packet size or on the number of neighbors? Thanks in advance, Alicia Triviño / Tl. +34-95.213.71.91 Dpto. Tecnologia Electronica E.T.S. Ing.

[ns] Security in MANET
Hi, I am new to ns. I want to implement a protocol in 'ns' that provides secure route discovery in MANET. It involves Digital signatures and encryption. I have studied the tutorials but they all provide information on how to simulate normal routing traffic without any security. Can anyone give me a suggestion on how to start which file to modify and how. What should i do to generate a MAC (Message Authentication Code) in NS. please help me. Thanks in advance subhash. |M.

[ns] GPRS simulation by richa...
Hello Richa, Would you Help me?I am simulating the wireless network at GSM. I want to try GPRS simulation using Network Simulator. I have gotten that source code but I can't install it. I have read the Readme but I didn't understand. And would you tell me about How to install your GPRS simulation and also the source code about GPRS module? Can you send about the information via email. Thanks for your help, Indra, __ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
[ns] Ending the simulation after a transfer is finished
Hi, Is there a way to end the simulation just after a transfer is finished and not by specifying a time on which to end it. For e.g.: my script has a line: $ns at 5.0 $ftp send 6000 Where ns is a network simulator object and ftp is an ftp application object. Now, I don't know at what time will this transfer be over. So, I can't have a line which says: $ns at 10.0 finish I also don't want to use a big number for the time over there because that will mean unnecessary waiting in most cases. Is there a way to end the simulation when $ftp is over with its transfer? In other words, is there a way to know the time when a transfer will be over? Thanks, Prateek Singhal -- Prateek Singhal | mailto:[EMAIL PROTECTED]
[ns] R: Ending the simulation after a transfer is finished
Prateek, setting the finish time to a high value should not cause any harm, nor should it make you wait more. Since ns-2 is an event-driven simulator, once no event is scheduled the time shall move directly to the 'end of simulation' event, in no (user) time. I don't know if other better solutions exist, though.

Hi Marco, I think this does not hold if the Scheduler type is Realtime, right?

[ns] Fw: route assignment code
- Original Message - From: Christos Antonopoulos To: ns-users@ISI.EDU Sent: Monday, July 03, 2006 3:17 PM Subject: route assignment code Hello everybody, I want to make a very specific question if someone knows it. I want the specific point in the code where a route is assigned to a specific packet. Could someone direct me to that point or to some relevant information? Thanks a lot Chris
Re: [ns] Keep track of nodes a packet passes through
Nicholas, I think you can find this information in a trace file, which should include a pkt id as the last field in the trace. Take a look at the tutorial here: http://nile.wpi.edu/NS/analysis.html Brad On 7/4/06 12:17 PM, Nicholas Loulloudes [EMAIL PROTECTED] wrote: Hello, is there a way in NS2 to keep track all the nodes a packet passes through en-route to destination?

Hi all, I want to generate a poisson traffic with average rate of 64kbps. So I wrote a script like follows and I just want to know whether it is correct or no. idle_time_ is set to 0.01 (=80*8/64000 pkt/sec). If anyone has an idea let me know. Thank you. set app0 [new Application/Traffic/Exponential] $app0 set packetSize_ 80 $app0 set rate_ 1000G $app0 set burst_time_ 0 $app0 set idle_time_ 0.01 Hirantha
