[ns] code for calculating performance metrics
hello everybody
am using NS2 4 my thesis and simulating a wireless n/w... i need to compare
performance metrics lik ( throughput,routing load, packet delay) for dsr and
aodv... and i dont have idea for calculating these could anyone plz, help
me in sharing me the sample code for these that retriving the datas from trace
files..
thank u in advance,
regards,
Priyanka

1)At first be specific. Determine which Link Metric is in ur consideration.
2)Then look for the suitable routing protocol that deals with those link metric
in contributed code for NS2 .
3) If it is available, move forward;
else write codes and incorporate it NS2 :(

Hi ns2 users

I send audio data from Node 0 to Node 4. The Link between Node 2 and Node 3
should be scientific overloaded. Therefor there is further UDP Traffic from
Node 1 to Node 5.
The Audio Signals are realised with a RTP Agent and a RealAudio Application
And here is my question:
Why does my Priority control not work? (It's in the Funktion
"attach-expoo-traffic")
I guess I forgot something but I don't know what.
Further my next problem?
How can I change the RTP package size of my audio signals?
Following my code:
proc record {} {
global ns sink4 sink5 f0 f1 f3 lf monFile ;#qmon samples
#Get an instance of the simulator
#Set the time after which the procedure should be called again
set time 0.025
#How many bytes have been received by the traffic sinks?
set bw0 [$sink4 set bytes_]
set bw1 [$sink5 set bytes_]
#Get the current time
set now [$ns now]
#Calculate the bandwidth (in MBit/s) and write it to the files
puts $f0 "$now [expr $bw0/$time*8/100]"
puts $f1 "$now [expr $bw1/$time*8/100]"
puts $f3 "$now [expr ($bw0+$bw1)/$time*8/100]"
#Reset the bytes_ values on the traffic sinks
$sink4 set bytes_ 0
$sink5 set bytes_ 0
#Re-schedule the procedure
$ns at [expr $now+$time] "record"
}
proc record1 {qmon samples} {
global ns monFile
set throughput [expr [$qmon set bdepartures_]*3.2/1.9]
set byteint [$qmon get-bytes-integrator]
if {[$samples cnt] != 0} {
set mean [$samples mean]
} else {
set mean 0
}
puts $monFile "[$ns now] $throughput [$qmon set bdrops_] [$byteint set
sum_] $mean"
$qmon reset
$samples reset
$ns at [expr [$ns now]+0.025] "record1 $qmon $samples"
}

[ns] what is this error "segmentation fault (core dumped)"
Hi friends i write a wireless network with 6node. i have an error "segmentation fault (core dumped)" if i reduce distance betwen node 5 and 6 this error dosen't show but i saw in nam, packets send from node 4 to 6 and dosen't send to node 5!! why ? my topoloy : node1--node2- node3-node4--node5---node6
[ns] Hashing in AODV - need help
Dear ns-users, Hope you are well. How can I implement hashing function/technique in AODV? Each mobile nodes has some data say some interger numbers. I have to implement hashing to search local database in each wireless nodes to find a specific data (for example, a number). Please advise what sort of coding required to do this and which file(s) those coding shoud be added. I desparately need this advise. Haven't found anything at the Internet so far for this. Please help me ns-users !! Regards.

[ns] Access to mac layer from above
Hi Guys I am currently running a wireless simulation with few (4-8) nodes. In order to gather statistics and analyse my simulation better I want to access all the mac layers of all the wireless nodes, do some calculations (average and std) and print the resulting data in the nam window. >From where can I access all the macs ? >From my understanding it's God that created all the mobilenodes, maybe can I add a function there ? The God object contains pointers to all mobilenodes, but I don't know how to access the mac layer with this pointer, maybe I'm totally miss something here, it would be nice if you could help me out here. And another thingy,.. how can I print to the console in nam ? (from the code itself - C++ and from the Tcl) :) Thanks Michael

Dear all, I am trying to install NS-2.34 on Virtual Ubuntu 9.04 over Windows Vista using VMWare Player 2.5.2. Looking in the ns-users list I found the following question similar to my results but for above settings: http://mailman.isi.edu/pipermail/ns-users/2006-November/057983.html I tried the allinone version of ns-2.34 I would appreciate if you could point me to a possible solution so I could install NS-2.34 in the environment I described.

[ns] proper implementation of a new protocol with all mobile nodes
I am working on a new message authentication protocol for vehicular ad-hoc networks (VANETs). I am relatively new to utilizing NS-2, a few months of working with it off and on. My whole simulation will consist of mobile nodes and use one of the routing algorithms designed for them (i.e. DSR, DSDV, AODV, etc.). I thought I was going along the correct route of creating my protocol as a new Agent and then using the OTcl portion to handle routing, link layer, MAC layer, etc. by using the node-config options. As of late I am doubting this because, for the DSR example, I see more and more examples referring to the actual DSRAgent code to utilize the DSR routing algorithm. So I guess one of my questions is, which should I be using? I know there are changes in the way NS-2 handles node creation but I don't know if the reason why I see the conflicting examples is because of that or because of another reason. Am I wrong in thinking my protocol should be at the Agent level as opposed to the Application level? I am wanting to control when a packet is broadcast/unicast and its contents. Marshall
