Dear NS users,
I couldn't find any source code for the testing of three interfaces ( WiFi,
UMTS and WiMAX) in NIST (Software mobility package for NS-2) module.
If anybody have the source code for the above, could please help me.
My scenario is like this (No handover):
I want to have different/same type of flows concurrently from a source node
with WiFi, UMTS and WiMAX interfaces to the respective destination nodes as
follows.
/O Dest 1 (for WiFi interface)
/1(WiFi Interface)
cbr1---> /
cbr2--->srcO _ _ 2( UMTS Interface_ _ _O Dest 2 (for UMTS interface)
cbr3---> \
\
\3(WiMAX interface)
\ O Dest 3 (for WiMAX interface)
Do you have any example tcl code for UMTS test or for alltogether UMTS, WiFi
and WiMAX?
Thank you in advance.
Best Regards,
Santos

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hi, all:
I knew NS2 provided a set of default .tcl files located in /tcl directory.
One of them is called ns_agent.tcl. Sometimes we need to add our own defined
agent such as OLSR. And we did so already. Then I run ns2 but it complains
the error such as :
--------
invalid command name "Agent/OLSR" while executing "Agent/OLSR set abc true"
--------
I had thought that maybe they're not in same directory as my current work
directory, so I copy the modifed ns-agent.tcl file to my work directory,
still same error occurs. My questions:
1. Which directory is supposed to be our own work directory which we create
our own tcl files? They're so many sub-dir under /ns-allinone-2.29/
2. Why my work file doesn't recognize the modified ns-agent.tcl ?
3. For these default ns-XXX.tcl files under /tcl, are they automatically
called whenever need? Do we need to export the tcl_library by adding this
directory?
Any suggestions? Thanks in advanced.
(This forum is really helpful, I love you and your great help..)
Best,

Hi ns-users,
in my script check a bit rate of 54Mbps and a frequency 5GHz. how to
verify if really these formulations are respected?
$phy_a set freq_ 5.0e+9 ;#5Ghz
$mac_a set dataRate_ 54.0e+6 ;# 54Mbps
in the file trace there aren't this type of information. Someone knows
where can I verify the values what assumes these statics variable ?
Thank you in advance.

Hi ns-Users:
Recently I install the debugger in my system following the Tae-hyung Kim
manual. All run ok.
But when I changed a file, for example, p802_15_4mac.cc and then do 'make
clean', 'make'; I dont see the changes. Why? The gdb say me: "warning:
Source file is more recent than executable".
My tcl script is in ns-allinone/ns-2.31/tcl/ex/wpan.
What is the problem?

hi,
I am looking for an NS2 extension package that supports static routing
(i.e. used in tree-based wireless mesh networks).
Is there anyone extending NS2 to support static routing? If you have,
could you please provide me the package (source code).
I know one such extension:
http://www.cse.iitk.ac.in/users/braman/tens/#4.3_Configuration_Of_Nodes
it goes with ns-allinone-2.1b9a-gcc32. However I spend several days but
could not install ns-allinone-2.1b9a-gcc32 successfully, for both linux
and Cygwin. Can anyone install succesfully this extension? If it's done,
please tell me how you do.
thank you very much.
-toan.

Just a wild guess: Some clock issue? Sometimes happens on machines when
booting between Windows and Linux and the clock isn't set according to a
format both OS understand.

Subject: setting packet size
Hi all,
I have a network and am trying to set the packet size of my TCP packets. I'm
a bit confused because I have a CBR attached to my TCP agent which also has
a parameter for setting packet size. Does the packet size of both have to be
the same and if not could you please tell me the difference between the two
parameter.
Thanks in advance

To: "ns-users" <ns-users@ISI.EDU>

Content-Type: text/plain; charset="gb2312"
Hi all,
I am working for dsr analyse and simulation. When I simulate DSR using
ns2-2.29, sometime I get very bad results, but sometime I can alse get
normal results.
I simulated dsr protocol in such situation:
In tcl: ifqlen set 50, 802.11 datarate set 11Mb, ratio range set 250m
dsr all opt enable, including ring 0 search, cache reply, salvage, shorten,
etc.
cbr:50n-20mc-4rate
scene:50n-300p-20M-900t-1500x-300y
I generated six scene files using setdest.exe in the same scene situation as
above show.
the results:
scene overhead??route/data/ratio??delay??s?? pdf(send/recv/ratio)
scene1??304901/184097/1.656198 0.426943 64292/55843/0.868584
scene2??7703/204136/0.037735 0.024476 64291/64208/0.998709
scene3??440132/188394/2.336232 0.767900 64211/50903/0.792746
scene4?? 664971/232313/2.862393 0.679598 64479/30500/0.473022
scene5??227687/179718/1.266913 0.499662 64277/61165/0.951585
scene6??8151/157065/0.051896 0.012842 64377/64339/0.999410
I think only scene2 and scene6 are reasonable results, and others are bad
results.
In .tr files, the main reason of the dropping packets is ifq and arp.
I have checked Maltz's article "The effects of on-demand behavior in
routing protocols for multihop wireless ad hoc networks".
Maltz did this simulation with datarate 2Mb, and all results seems OK.
I don't know what's wrong with my simulation. Can anyone help me! Thank you
very much.
