[ns] error in awk data extraction
Hi :I'm using the old trace format in ns2 ,I have an awkscript that is calculating parameters for routing ,I am able to calculate all the dropped,send and received packets ,but when I calculate pdf,and normalized routing load I'm getting the error : awk: run time error: improper conversion(number 1) in printf( 4. Normalised routing load (Packets %) = %.3f % ) FILENAME=simple1.tr FNR=23418 NR=23418 can anybody tell me what's the problem ?Please reply asap .
[ns] trace2stats v0.5b awk support help understand
Hello all I wanted to know if anyone has used trace2stats v0.5b awk scripts for wireless formats, and if you can explain me the jitter file in it. I mean we have 4 different values of jitter, and the calculations in the script dont explain me fully which jitter you would look for finding out whats the jitter for that particular communication. Can someone please help me for this? Also explain me what is this instant throughput there?we have flow id,what is it ?we have source node and dest node,if I put source node=2 and dest node =3 and tic=3 secs I get the results of throughput after 3 seconds to how long ?I mean can somebody please explain me the results ?
[ns] control overhead in sn2 for aodv
How can I measure control overhead in ns2 for routing protocol comparison?I want to compare aodv and dsr in terms of which protocol generates less overhead .How can I do that?Should the overhead include AGT as well as RTR ?and what about mac layer packets ?can someone describe that for me?and is there a difference between normalized routing load and control overhead ?
[ns] awk script from mailing list
Hey i found the awk script from mailing list,wondering if this would
function,but it doesn't
can anyone tell me why ?
from mailing list :
Plz see the following awk scripts that calcualate the following
Performance Metrics Used
Routing Overhead
Normalize Routing Load
Packet Delivery Fraction
Average End to End delay
Jitter
Drop Packets
Drop Bytes
Throughput
These scripts work with new trace format and DSR protocol. Make changes for
other protocols.
As an example, if you want to calculate throughput,
awk -f throughput.awk output.tr

[ns] trace2stats for awk
http://perso.citi.insa-lyon.fr/mfiore/research.html
the website has A set of AWK scripts to get node-to-node statistics from the
tracefiles generated by the ns-2
network simulat
,the awk script for instant throughput,instant jitter and avgstats but when I
run any of them i don't get the results in any case just blank lines ,I'm using
the new trace format as stated in readme file .
this is from instant throughput script in awk

I have a question is this the correct field setting values because I think $5!=

if it is ,then why is it note working please reply .

[ns] olsr for 30 nodes takes a lot of time
Hey I wanna run olsr simulation ,I've successfully patched olsr in ns2 2.34 ,from masimum site.tell me can I use the same tcl script as that of aodv for instance,and It takes a lot of time for olsr simulation ,how can i simulate it quickly
[ns] routing protocol for wireless mesh network
Hey can anybody guide me in developing routing protocol for wireless mesh network,any article book or anything useful .
[ns] routing algorithm for wireless mesh network
I asked earlier how can i develop routing protocol for wireless mesh network ,people recommended me to http://fikirankubuntu.blogspot.com/2010/03/adding-new-routing-protocol-in-ns2.html but I ask you this is developing new routing protocol in ns2 ,so to develop that I must have my own routing algorithm ,right? How do I do that ,make my own routing algorithm ,i.e. clearify me that the protocol developed in ns2 have their own algos,how do I make my own,What should i study for that?

[ns] routing protocol comparison
Hi i don't know why the community people aren't replying with useful info.I just am very disappointed.I wanna simulate routing protocol for manet simulate research paper (some ) and calculate parameter like those calculated and plotted in the papers using xgraph ,gnuplot or whatever but don't know,anything no one is helping very well ,I just need some scripts tcl and awk and be able to plot the results also wanna know how to be able to simulate any research paper for manet like performance comparison of manet routing protocol.
[ns] extracting trace file information
Hiey can anyone tell me what's the best way to extract trace file information? awk or perl ? and how can i extract information for manet routing protocol like pdf,average end to end delay ,latency ,throughput via both perl and awk scripts.Do they produce the same results ,of course they shoud ,but what is better in anyway ,just let me know .
[ns] xgraph again no response
Hi i am working in ns2 for performance comparison of manet routing protocol like aodv and dsr ,I get the result in nam ,but don't know how to plot routing overhead ,pdf,end to end delay etc using xgraph ,please guide me
[ns] 802.11 standards for latency and pdf
hello guys..i need some help here. does anyone has references about standard QoS value such as latency,delay,packet loss for voice in IEEE 802.11? i would like to compare my simulation results with the real. thanks before
[ns] comparing simulation of aodv and dsr
Hey how can I automate my simulation, can anyone tell me whether it is right that run the simulation for aodv like 15 nodes and same tcl script for dsr and the dsdv ,Is this the right way to compare simulation ? or would I have to write a comparison tcl program,? How close my simulation results can be to rght ? how can i calculate routing overhead,average end to end delay,pdf,etc ?perl or awk script with step by step guide are required.thanks

Hi ,I am using ns2 2.34 on ubuntu 11.04 in virtualbox, and I can't patch olsr http://masimum.dif.um.es/?Software:UM-OLSR:Installation i 've tried details given in this link yet i can't do that.it gives me error when i run this patch -p1 olsr/um-olsr_ns-2.29_v0.8.8.patch gives no directory or command or something like that,
[ns] olsr patching issue
i get the following error when i tried the olsr patching from masimum Installation of otcl seems incomplete or can't be found automatically. Please correct the problem by telling configure where otcl is using the argument --with-otcl=/path/to/package (perhaps after installing it), or the package is not required, disable it with --with-otcl=no. after i configure it what should i do ?
[ns] Xgraph plotting packet delivery ratio and throughput
can anyone please tell me how to plot packet delivery ratio and throughput via xgraph ,Please provide detailed description ,I've posted many times but not satisfied with the answers,i have to plot the graph for aodv and dsr for 30 nodes and 45 nodes ,tcl and awk scripts are required.

[ns] trace file analysis
Dear all, I've read some research papers in which they compared performances of different routing using some normal performance metrics, such as: Packet delivery fraction routing control overhead Average end-to-end delay Average number of hops .. How can we have these things using Ns2 simulation ? I can not see it from trace file after simulation. I really appreciate your help! Regards,

[ns] DSR AND AODV XGRAPH AND TRACEGRAPH
HI I wanna produce comparison graph for aodv and dsr using xgraph.How do I do that ?I don't know anything about using xgraph.and what is the difference between tracegraph and xgraph?How can I compare for 40 nodes of AODV AND DSR?WIll it be a single tcl script containing both protocols and xgraph or I have to run separate simulation.Please detailed help will be really appreciated as I am new to ns2
[ns] AODV and DSR
