Re: [ns] Node movement
Hi, I'd use a external script to avoid doing too much by hand. I don't know how much nodes and movement changes you're talking about, whether it's feasable by hand or not kind of depends on that. 1) Basically you need the initial position of each node (two-dimensional): $node_(0) X_ $node_(0) Y_ $node_(0) Z_ 0.0 2) and for each movement change a command like this: $ns_ at "$node_(0) setdest " If you already have the intermediate positions at fixed times and your speed is non-uniform, you will need to calculate the speed first for each pair of positions. This would be done by a formula something like the following (pseudocode): speed = squareroot[(new_x - old_x)² + (new_y - old_y)²] / (new_time - old_time) 3) After that, if you have a properly formatted file with initial positions and position changes, you can use the "calcdest" command to calculate the shortest hop information for the god_ object. It can be found in "indep-utils/cmu-scen-gen/setdest/". If you don't do that beforehand, it is done during the simulation and might take a lot of time (strongly depending on the number of nodes). I've never used calcdest myself, so I can't advice you on that. 4) Finally, include the resulting file in your simulation script source As I said, I'd write a short skript that does steps 1-3, if you have many nodes and/or movement changes.

Re: [ns] setting error rate for two state error model
Yes, with your configuration you will have an average error rate of 5% but in a very particular way. During 0.95 seconds you will receive all the packets correctly and then you will have errors in all packets for 0.05seconds, then again 0.95 seconds of error-free packets and so on... I don't know if that's what you want.
[ns] "rate_" parameter in Exponential traffic
Hello there, I am not sure the setting of "rate_" in Exponential traffic I wanna generate data traffic with rate of 16kps , and packetsize is 40Byts. burst_time 450ms, idle_time 50ms, In my calculation, 16kps = rate_ * burst_time / (burst_time + idle_time) , so I get rate_ is 17.778 k Is it right ? or just set rate_ = 16k? Regards Image,
[ns] ns debug
Hi all does 1)'-g' added to CCFLAG variable in the Makefile and 2)'--enabled-debug' ./configure parameter equivalent ? I mean do I just use one of them to enable DGB or other debuggers? Best regards Ramzi Tka
Re: [ns] voice and video traffic in ns2(help)
Hi Ghazale, I am also working with simulation of audio and video flows. Well, I may be wrong in my approach, but all I did was creating a simple CBR traffic generator over UDP. I have also made some real tests for getting some parameters for supplying NS2, such as MTU, packet size, and rate. Of cource, this scenario can vary as our needs are distinct. For instance, if you are simulating voice transmition for telephony purposes, you propably should use TCP instead of UDP. Moreover, CBR is apropriate for the set of applications I am interested in. Maybe the VBR model is better suitable for your objectives.

[ns] How we generate packet using echo agent for mobile nodes??
Hello dear all,
I am working on intrusion detection system for
wireless ad hoc network,,
my routing protocol is AODV+(not AODV)... like
wireles-cum-wireless when MANET connected to the
INternet
ok according to this introduction
I need to add some echo agent as a generator of attack
packet,,but i dont know based on the NS MANUAL
documention i add echo agent like that:
#set echoagent [new Agent/ECHO]
#$ns attach-agent $mobile(8) $echoagent
$echoagent set dst_ $mobile(7)
$echoagent set fid_ 0
$echoagent set prio_ 0
$echoagent set flags_ 0
$echoagent set packetSize_ 1024
$echoagent set interval_ 1.5
$echoagent start
###$ns at $val(start-src) "$echoagent start"
###$ns at $val(stop-src) "$echoagent stop"
##
and i got the below error may you plz simply let me
know how can i add a echo agent
what is wrong with me??
Thank you in advance
