[ns] WFQ implemantation
hi @ all, is it possible to implement the WFQ algorithm in ns2 ? is it possible to make some link dependent each other in terms of service time and bandwidth? i want to implement many queues, each of them goes in the same server...quite like the philosophy of a radio link but I'm interested to the tcp behavior so i cannot use the wireless nude becaus is affected by all the problems of a wireless link thanks in advance Davide
[ns] Wireless Scenario Generator for NS-2 using MATLAB GUI, Help for some Developments
Hi every body, I've implemented a simple scenario generator for wireless networks to make it easy to simulate wireless nets on NS-2. By the way it's almost customized and I want to develop it for a general field in wireless simulation. That was not so easy for me to compile some available open source scenario generators on windows OS so I made my own using MATLAB GUI environment. Also I've some problems with NS-Mapper software, for example it was not allowed to save settings or running the generator because some plug-ins was not available on my system. My S-Gen is so easy to work, using a very friendly simple environment and I'm trying to make it as friendly as NS-Mapper. So I want to know if you can help me to complete this generator deploy it for distribution as an easy to use Scenario Generator for NS-2 wireless simulation. You can download My_S_Gen source files following this link : http://mailman.isi.edu/mailman/options/ns-users/[EMAIL PROTECTED] Best regards. Hamid Shiri (Phoenix) Email : [EMAIL PROTECTED]
[ns] Is antenna position relative to node position?
Hi, I want to calculate the value of received signal strength, so I need to know the position of Mobile Node and Access Point. And I found something interesting in the file mobile/propagation.cc Xr += r-getAntenna()-getX(); Yr += r-getAntenna()-getY(); Zr += r-getAntenna()-getZ(); Xt += t-getAntenna()-getX(); Yt += t-getAntenna()-getY(); Zt += t-getAntenna()-getZ(); And I print out these values : Xt 589.478206: Yt 489.478206,Zt 0.25:Xr 589.478206,Yr 489.478206:Zr 0.25 Xt 600.00: Yt 500.00,Zt 0.25:Xr 600.00,Yr 500.00:Zr 0.25 Xt 589.487894: Yt 489.487894,Zt 0.25:Xr 589.487894,Yr 489.487894:Zr 0.25 Xt 620.503211: Yt 520.503211,Zt 0.25:Xr 620.503211,Yr 520.503211:Zr 0.25 . To my surprise is that the values of Xt,Yt are variant which are supposed to be invariable because the AP is fixed. So, How to explain these codes? Is antenna position relative to node position?

[ns] Simulation of broadcasting nodes interpreting trace file
Hello all, I am trying to do a comparative study of two wireless standards by using one broadcast protocol in which there are 25 nodes and every node broadcasts its message after every 0.25 secs. After running the simulation, the trace file corresponding to it got generated but am not able to identify as in what are the parameters i can extract using the file as in all the packets are transmitting ideally after regular interval so if i want to to do throughput analysis, or delay or of packet loss so i should do that for a system as a whole or by considering any node? Also i don't know how to interpret and extract information from he trace file generated. I read many reviews and searched a lot about the awk script but am still unclear. I tried using tracegraph but what i am suppose to do after i convert the *.tr file into *.mat file? Please someone help. Thanks and Regards, -- Vishal
[ns] how to use tracegraph
Dear users, I am trying to use tracegraph for interpreting and extracting information from my trace file. Can anyone please tell me the steps which i need to follow to install and then use it to do some analysis. I have matlab 7.0 installed on my computer. Thanks in advance -- Vishal

Re: [ns] SplitObject error after adding a simple print function

and call this in my TCL like this:
for {set i 1} {$i $nodes} {incr i} {
$ns_ at 10.0 $node_($i) rt_print

But I get an error:

_o32 cmd rt_print

catch $self cmd $args ret
(procedure _o32 line 2)
(SplitObject unknown line 2)
invoked from within
_o32 rt_print
Does anyone know how to solve this SplitObject error. From my understanding,
SplitObject error is caused by no having a corresponding C++ object used in
TCL. Any pointers??
Or If I want to print out the routing table in AODV, how do I do it?
Many Thanks,
Asraf.
In your TCL script, you have called rt_print as :
*$ns_ at 10.0 $node_($i) rt_print*
This is as if it is a /procedure of NODE object/, (which is certainly
not true here!). Rather you should call it as
/ ... $val(rp) rt_print/
where, $val(rp) is your AODV, adhocRouting. You can now fine tune
yourself as per your need.

Re: [ns] errors when type make
It seems your compiler considers the declaration of char** p_info::name_ char* is different from the definition of p_info::name_ [59].
