Re: [ns] install ns228 on suse10.1 fatal problem
Try this Dear Qasim, you are right. The problem seems to be related to the gcc version. Fortunately there is a patch. The instructions can be found at http://mailman.isi.edu/pipermail/ns-users/2006-May/055811.html in case you want to fix your friend's NS2 installation some time. Thank you very much. Cheers, Markus Qasim Raza Iqbal wrote: No Unfortunately I could not find the solution to that problem. As this was one of my friend's computer who just started research. I think it will be some time before we try to load ns2 again as he is working on somethng else. However one reason could be that we were trying to install NS2.29 on the Latest version of linux with gnu compiler version 4.10, and it did not compile. Maybe if you try a the compiler version less than 4.0, then it will probably work before you try to install ns2 please check what version compiler you are using e.g type gcc -v If its 4.0 or higher, than that could be a problem. I hope this might help kind regards Qasim Iqbal Aston University Hi Qasim, you posted a problem on the NS2 mailing list on April 28 regarding tcl8.3.2 configuration on Cygwin. I ran into the same problem. Did you find a solution? Maybe it is worth posting it on the NS2 mailing list, since the problem has been reported recently to occur with Debian Linux, too. Yet, in the mailing lists I could not find a solution. Thank you very much. Kind regards, Markus Dear all, i am trying to install ns228 on suse10.1 32bits version.(i have tred other version conbinations but all failed, could anyone suggests successful ones?) failed and get last line of hints as following checking system version (for dynamic loading)... ./configure: line 7068: syntax error near unexpected token `)' ./configure: line 7068: ` OSF*)' tcl8.3.2 configuration failed!

Re: [ns] what's the relationship of Pt_ and -txPower ?
Hi David What you need to do is look at NS Archives, This topic has been discussed several times and in great depth. go to this website http://www.isi.edu/nsnam/htdig/search.html and type in your question e.g RXThresh, Transmit power , etc, and you will get loads of hits regards Qasim UK Dear friends: We know that we can set different Pt_ and RXThresh_ to get different transmit range. We also use energy model to calculate the energy used on transimitting by setting -txPower. Then what's the relationship of Pt_ and -txPower? Should Pt_ be greater than -txPower? During my simulation,I found I can set -txPower to a small value,for instance, 0.025. However, I can still set Pt_ to the default value which is 0.281838 and it works fine. Than I am confused, if the power consumption of Transmit is 0.025, how can Pt_ be so large? Anyone help me? Thank you for your suggestions! Regards! David

Re: [ns] Values to be set in the TCL file to make the transmission range 100m
Hi Jeevash There are two method to do it. Method a) You calculate the RxThreshold using a small program written in C called threshold.cc locayed in the folder ns-2.29/indep-utils/propogation/ compile the file as g++ threshold.cc then run the program /a.out with the required distance you want to transmit. In this case the transmit power remains the same as 0.2818 (default 250m) and also the Carrier Sense Threshold (CSThresh) will remain 550+ but the nodes that are 100+ meter away will drop the packages that they receive considering it an error. Method b) You only change the Pt_ value to 7.214e-3 , This will set the maximum transmission range of the node to 100m. so you can choose which option you want to go for I hope this helps regards Hi friends, What are the values to be set in the TCL file to make the transmission range 100m. In some mail i got some pointer for this but i am not getting them clearly. There i have to set Pt_ variable to a fixed value. Is it the only value I have to change? or it need some more changes. Then what is the use of values written below other than Pt_. CPThresh_ 10.0 CSThresh_ 1.559e-11 RXThresh_ 3.652e-10 Rb_ 2.0e6 Pt_ 0.2818 freq_ 914e+6 L_ 1.0 Please help me.

Re: [ns] How to measure energy consumption of wireless nodes
Hi there Could you also send me a copy of the solutions to your wishlist thanks Qasim Iqbal Hi Gurus, I am a newbie in ns2 and I need to evaluate the energy consumption of AODV. My plan is to have the nodes send/receive data for a period of time and measure the energy difference from the beginning to the end. Could anyone instruct me how to do this. In detail: 1) How to set the energy model + initial energy correctly: some of my nodes are mobile, but I only need to measure the energy for routing/sending/receiving data. The energy for node movement is simply ignored. 2) Do I need to enable any options in ns to be able to track the energy. 3) How to read the energy from the beginning and at the end ? Please give me some detailed instructions as I am just a newbie in this field. Thanks a lot for your help. Heo - Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.

Re: [ns] How to get the position of node in Tcl (NS2 Command)?
OK, its there but you just could not find it. Another place to look at is the example in NS2 manual Look at section 16.1.2 Creating node movements, at the end of that page there is a working example procrdure that shows how to log movement very 0.1 sec,, I am sure that will help you. I have tried that and it works fine regards Qasim Thank you for your help.

Re: [ns] simulating CAN in ns2
I know Controller Area network is a totally different protocol from 802.11, which composes of one or two wires for sending data with the maximum data rate of 1 MHz I have not seen CAN using a wireless protocol, even though I have worked on CAN using optical fibres Nor have I seen CAN protocol implementation in NS2. However to simulate CAN you will have to right your own simple protocol module The research paper linked below recently did some work based on CAN network using NS2 http://vorlon.cwru.edu/~vxl11/NetBots/Infocom05.pdf Are you aware of any CAN (Controller Area Network) implementations for ns-2?

Re: [ns] why node 3 is not define?
Hi,
I also have that problem, infact in my case when running nam for a similar
scenario, it shows me node 0,1,2 and 3 a not defined until they actually
start the movement.
Another think which I need to ask you is that why have you attached the
same tcp to node 0 2 and 4 and sink to node 1 and 3. Can you use the same
agent on different nodes? Is that a requirement for the channel to work
properly or your just testing to see it works
Please let me know
regards
Qasim Iqbal
hi ,
i don't know exactly, why it worked by making single change. But i made
the change by guessing it as hidden terminal problem.
Exact reason is most welcome.
The modified line is highlighted with yellow and i have changed 20.0 to
10.0 in that line which is highlighted with blue.
