[ns] How to pass information from Mac layer to Networking layer
Hello Evryone, I am a newbie in ns , trying to pass some information from mac layer to L3 (ie. to the aodv agent); what i need from AODV agent is to have a mechanism to go and periodically check some parameters in MAC layer. Until now I could not find any such implementation guide on the net;any help is more than appreciated!

[ns] Urgent:Need help for MANET(Wireless scripts)
Hi ns users, My problem statement is also given below Topic:Location Management in MANET using NS2(using Wireless scripts) I have already gone through Marc Griegh Tutorial and ns Documentation but failed to find any suitable answer I want to send the packets to different multiple destinations from single sender(mobile node 1 acts as source remaining act as Destinations) if acknowledgement is recieved the mobile node is located otherwise i have to retransmit the packet(Plz anyone can tell me how to retransmit the packet after setting time intervals for each mobile node) for 10 mobile nodes I can find the packets sent and acknowledgement from tracefile but how can i transmit the packets for which the packets sent from sender to reciever failed so how to retransmit TCP,UDP Packets. Bandwidth allocation for each mobile node is also one problem which needs to solved. Kindly help me Thanks and Reg: Vijay
Re: [ns] How to read the current value of a variable ?
Hello Mouli, G.Chandramowli wrote: I am trying to invoke an event at specified time . The event does something based on value of a variable. And the variable keeps on changing during the simulation . When this event is invoked , it reads the initial value of the variable only and not its current value . Any idea on how to fix this I'm not sure if I get you straight and I've only just started using ns-2. Being aware of that, could it be possible that every time you read that variable it might be a new instance of the corresponding object and thus it gets re-initialized in the constructor? If that's the case, it might help declaring the variable as static. HTH, --Timo

Re: [ns] segmentation fault
This is a generic message caused most probably by misbehaving pointers. Your best shot is to use a debugger, e.g. gdb. It will pinpoint the source code line causing the error for you.

[ns] R: Re: Awk script for Jitter in NS2
For the question on the jitter, you can find the formulae in the read. me. There's no right formula, I used to employ the first, which is defined in RTP's RFC. I added the other three upon request of other users, who usually employed them for jitter calculation. Regards, Marco Messaggio originale Da: [EMAIL PROTECTED] Data: 11-mar-2007 11.13 PM A: ns-users@ISI.EDU Ogg: Re: [ns] Awk script for Jitter in NS2 Regarding your second question, my understanding is that -Hs is the node at which the event is observed, and not necessarily the source. In receive events, -Hs is the node receiving the packet and hence Hs = Hd (the receiver is the observer of the event) and other subsequent fields will report the actual source.

Can someone please help me for this? It would be a great help. Also, I had asked this que before, I wanted to know during post analysis generally we look at the AGT level right? But in my simulations, I am getting AGT in 's' but if that AGT in 's' is for lets say Hs-2 to Hd-0 then at receiving I m not getting r with Hs-2 and Hd-0, then does it mean ther is a flaw? Also I am getting r with Hs and Hd both 0. Can anyone please help me with this. Thanks in advance.

Re: [ns] How could I know if my NS is working right?!
Hey, if you are a new user to ns , try the link below. It's a simple tcl program. Download it, save it in a folder and run it. http://nile.wpi.edu/NS/Example/ns-simple.tcl Running command is: $ns ns-simple.tcl You must make sure you have added/exported the PATH shown after completion of the installation. If it's working right you will have an output file called out.tr and out.nam in that folder. maruf - Original Message - From: super.ismiti [EMAIL PROTECTED] Date: Monday, March 12, 2007 1:42 pm Subject: [ns] How could I know if my NS is working right?!
