[ns] how to dump routing table
Hello, I am simulating a large network which uses a link state protocol ($ns rtproto LS). I wanted to find out if there is way to dump the routing table of each router i. on screen ii. in a file I would really appreciate if someone could help me out with this! Thanks and Regards Kanupriya
Re: [ns] Problem with NS2 installation
Hi, obviously this NS isn't the simulator. Use which command to locate where is the command NS: "which ns" the output must be a path to that ns executable. This will help you to find this alien NS. Anyway, you must put the correct path to NS (simulator) in your PATH variable. Ask google for a tutorial about how to change PATH variable in Linux. It's easy. Put the folder of NS in first place, so when you type NS, the correct NS will be executed.

[ns] Problem with NS2 installation
Hi, Im a totaly newbie on linux and a couple a days ago i installed ubuntu in order to use ns2 (Network simulator) I used a the tutorials i found on the net,and didn't get any errors during the installation. When i wrote 'ns' in the terminal i get this : Usage: host [-v] [-a] [-t querytype] [options] name [server] Listing: host [-v] [-a] [-t querytype] [options] -l zone [server] Hostcount: host [-v] [options] -H [-D] [-E] [-G] zone Check soa: host [-v] [options] -C zone Addrcheck: host [-v] [options] -A host Listing options: [-L level] [-S] [-A] [-p] [-P prefserver] [-N skipzone] Common options: [-d] [-f|-F file] [-I chars] [-i|-n] [-q] [-Q] [-T] [-Z] Other options: [-c class] [-e] [-m] [-o] [-r] [-R] [-s secs] [-u] [-w] Special options: [-O srcaddr] [-j minport] [-J maxport] Extended usage: [-x [name ...]] server [name ...]] The guide says i should see a '%' instead of '$'... When i try to run a tcl file using the command 'ns example1.tcl' I got this : Nameserver not running example1.tcl NS record not found, try again Did you come up with this problem?

[ns] ns and http
how to attach an http application on an existing TCP Agent? i use nsmiracle and i cannot create the http application directly attached to the node because (because i'm using the nsmiracle node that is quite different from the normal ns2 node) i'm able to create the tcp agent and attach onto it the application (like FTP) but is not the same with http any help will be appreciated Davide
[ns] wireless network parameters
hii m simulating a simple scenario with 4 wireless nodes, one BS linked to
wired node the each wireless node send an UDP trafic i varied the UDP rate from
1Mbps to 10Mbps and although the MAC data rate is equal to 10Mbps, the average
throughput that i mesured didn't exceed the 0.90Mbpswhen the UDP datarate is
1Mbps,for UDP datarate 20 Mbps the total average throughput at the wired node
per example is 3.57Mbps.i m confused about the reason and i look for an
explication:for the loss rate for instance when datarate =1Mbps the loss rate =
55.4307 last thing is that i don t find in the new trace the reason for the
dropped packets in the field Nwcan someone help me thank you my script tcl set

Re: [ns] Transmission power
Hmm.. But the case is that I am developing a protocol and the trasmission power will vary according to what it wants, so there is no way I could set the TP individually for each node on my TCL script, since its value will depend on some events that can not actually be foreseseen. Can I set the TP value from inside my C code?

Re: [ns] Transmission power
Hi, You can set the transmitted power, by varying the "Phy/WirelessPhy" parameters in your tcl script. Please refer to the following conversations: http://mailman.isi.edu/pipermail/ns-users/2005-March/048467.html You can also see, the threshold.cc file ... ~ns/indep-utils/propagation/threshold.cc and Chapter 18:Radio Propagation models of the "The ns Manual" Hope you'll find it helpful, Regards, Vineet [EMAIL PROTECTED] wrote: > I would like to know how to change a node's transmission power when > sending a message.

Re: [ns] Large network simulation problem
I tried the following: ns-2.29-2 (precompiled from repositories) ns-2.28 ns-2.33 and my simulation still doesn't work properly. The results, expecially for DSR protocol are still very bad. The ns script and the awk script are in this post. They are not the most recent version I am using now but results doen't change. Can someone explain me what may be the problem?
