[ns] Dear all
Dear all
I have one stupid question can some one tell me how can save file in terminal
for example I have written the following tcl file I want to save it as tcl file
:
% set ns [new Simulator]
_o4
% set nf [open out.nam w]
file3
% $ns namtrace-all $nf
file3
% proc finish {} {
global ns nf
$ns flush -trace
close $nf
exec nam -a out.nam
exit 0
set n0 [$ns node]
set n1 [$ns node]
$ns duplex -lnk $n0 $ n1 1mb 10ms DropTail
$ns at 5.0 finish
$ns run
how can I save this file as tcl file in the home directory. Iam new in NS2
Re: [ns] randomizing runs
Hi Abu, By default, NS2 is deterministic. If you would like to run NS2 in randomized scenarios, you need to execute $defaultRNG seed n prior to $ns run, where n is an integer. If n is zero, NS2 will use the current time and counter as a seed for random number generator. By default, n is set to 1, meaning every run would generate the same result. You may manually change the seed (e.g., 2, 3, 4, and so on), or set it to zero. I also posted the details on my blog at http://t-issariyakul.blogspot.com/2009/09/ns2-deterministic-vs-random.html For more information about Random Number Generators, see Chapter 12 in the following book from Springer: T. Issaraiyakul and E. Hossain, Introduction to Network Simulator NS2, Springer 2008. http://www.springer.com/engineering/signals/book/978-0-387-71759-3 You may also find the following website useful: http://www.ece.ubc.ca/~teerawat/NS2.htm Best Wishes, Teerawat On 9/18/2009, abu shahriar azmshahr...@gmail.com wrote: Hi all, I am in trouble with randomizing ns run by seeding defaultRNG or ns-random.

[ns] multi-phases MAC protocol simulation
Hello! I have to simulate a two phases MAC protocol in which nodes apply in every phase a different algorithm and exchange different packets , I have to execute an algorithm in background and exchange it's result in the first phase than use those results to elect the node that have the right to transmit it's data packet in the second phase . I will appreciate any help or idea for how to simulate that, have I to use OTCL threads or can I do it in only one MAC C++ file ? I have no idea about how to start !! Thank you very much in advance. _ Windows Live™: Keep your life in sync. Check it out! http://windowslive.com/explore?ocid=TXT_TAGLM_WL_t1_allup_explore_012009
Re: [ns] [Ns-developers] Added Grid for nam-1.14
ori and mish bgu wrote: Hi Everybody I was working on wireless simulation for some time now and found that draw lines of grid (on the topography) with distances in the nam visualizer was very useful for me to know exactly where nodes are placed in the network, especially when simulating dynamic networks and testing dynamic networks behavior. I thought it could be nice to share this modified nam version with you guys, maybe someone could find it useful. How to install it: Copy and replace the files view.h and view.cc with the ones that are in the /nam-1.14 folder. Copy and replace the file build-ui.tcl with the one that in the /nam-1.14/tcl folder. In the terminal window (under the /nam-1.14 folder) type: ./configure sudo make sudo make install How to use it: To add the grid in the nam window, click Views - Show grid. To increase or decrease the grid click on keyboard + or - buttons respectively. Note that I don't have any previous experience of nam programming and I have'nt found any documentation. There may be some more elegant ways to program it, but it works for me. Michael Hi Michael, Thanks for posting this-- I created a tracker issue for this and will review it sometime soon. - Tom http://sourceforge.net/tracker/?func=detailaid=2868455group_id=149743atid=775394
