getting following errors in my tcl script named testpr.tcl

Re: [ns] validation of saturation throughput in 802.11
Thanks for your help. I expect the error is less than 0.01 (i.e. when 20 nodes, 0.71-0.70=0.01) , Is that reasonable or achievable? I found the ns-2 results in some paper matches very well with Bianchi's model (less than 0.01). I wonder how to achieve this accuracy. Is there any amendment needed to conform the ns2 implementation to the model? Moreover, I found the results are closer when I changed the scenario from 200x200m to 100x100m. Is it because that the default transmission range is 250m in ns2, so that some stations may not be able to send packets to its destination in 200x200m scenario, so it overestimated the throughput? Here are the results, could the model and ns2 match any closer? nodes1020 3040 Model 0.76 0.70 0.66 0.64 Sim(200x200)0.77 0.72 0.69 0.68 Sim(100x100)0.76 0.71 0.68 0.65 >From: "Joshua Robinson" <[EMAIL PROTECTED]> >To: "? ?" <[EMAIL PROTECTED]> >Subject: Re: [ns] validation of saturation throughput in 802.11 >Date: Thu, 21 Dec 2006 16:19:00 -0600 > >do not forget that both model and simulation are not perfect and so it >is not reasonable to expect an exact match.

[ns] problems executing .sh (shell script) in ns2.29.3
Hi all, I've encountered the below mentioned problem: rm: cannot remove `1.txt\r': No such file or directory (this is one of error which basically that any stuffs I have included in the file, even if it is comments e.g. # TEST, there is error as well) when trying to execute ./sh (shell script) after installing cygwin and ns2.29.3. Previously, I didn't encountered this problem when i run this same shell script on my previous installation of cygwin and ns2.29.3. However, I have removed it and just recently, I reinstalled both and this error appears. I even uninstalled and re-installed cygwin/ns-2.29.3 several times. Can someone please kindly help me in this? Thank you very much. Would appreciate your help greatly. Best regards, Karena _ Find singles online in your area with MSN Dating and Match.com! http://cp.intl.match.com/eng/msn/msnsg/wbc/wbc.html

Re: [ns] validation of saturation throughput in 802.11
Thanks for your help.
But I didnot take overhead into account, and both my model and simulations
used the same packet payload with 1000 bytes and DSSS settings. I used
Bianchi's model but did not use his system parameters.
Here is the awk script. Every station starts sending at 1.0 and stops at
600.0, and I set channel bit rate to 1Mbps.
==
BEGIN {
recv_size=0
first=0
hdr_size=0
startTime = 1.0
stopTime = 600.0
}
{
if ($2 == "-t") {
event = $1
time = $3
node_id = $5
flow_id = $39
pkt_id = $41
pkt_size = $37
flow_t = $45
level = $19
}
if (level == "MAC" && event == "r" && pkt_size >= pkt) {
hdr_size = pkt_size % pkt
pkt_size -= hdr_size
recv_size += pkt_size
}
}
}
END{
printf("average throughput:%f kbps\n", (float)recv_size/(stopTime -
startTime)*(8/1000))
printf("start time %f stop time %f\n", startTime, stopTime)
}

Re: [ns] validation of saturation throughput in 802.11
Have you takein into account IP/UDP overhead? Note that Bianchi usually provides throughput at MAC layer and uses 1024Byte frames to show his results. That's all I can say with the details you provided. 2006/12/21, ? ? <[EMAIL PROTECTED]>: > > Hi all, > > I am validating the saturation throughput of bianchi's model , however , I > found my results do not match the model well.

[ns] VoIP with VAD
Basically, in continuation t o my previous mail, I am trying to simulate VoIP application with Silence suppression.

[ns] VoIP Traffic Generator
Hello All I have followin two questions: 1) Can anyone please tell me how to simulate VoIP traffic generator using G.729 codec. I read somewhere on the mailing list, that we have to modify CBR traffic for that, but that was in archives and I am not sure, if we already have now G.729 support as traffic generator in NS?/ 2) Can anyone suggest me a variant of DRR or WFQ scheduler whcih I can use in the Wimax Module, I am trying to work on. I would appreciate if someone can help me witht htis.

[ns] {Spam?} diffserv + mobileIP
Dear all, i'm testing some wireless scenarios that would help me for my research. I have a difficulty to configure the policies of the scheduler because of the hierarchical type of address (ex: MobileNode: 1.1.1) is, in a certain way, incompatible with the current inputs of diffserv. In wired environment i use(ex): $q1_2 addPolicyEntry [$W(0) id] [$W(1) id] TokenBucket 20 $cirAF3 $cbsAF3 In a wireless mode, ns tells me: No Policy Table entry found for Source 0-Destination 4194305 This Destination is, i suppose, the mobility node with the hierarchical type of ip. Any solution for this "problem"? Thanks in advance. Alexandre

Everything going further is implementation and protocol specific. If you want some hints and an example implementation take a look at the wpan folder for the zigbee protocol. The university washington had also made some improvements - google for washington university zigbee... The thing to do is in general simple and straight forward: get the time spent in different states, like sending, receiving, idle, sleeping(...) and hand them over to the energymodel with the corresponding energyconsumption. The problem is to find each of the values and the right parts of the code to insert the statements... I don't know any papers that explain the implementation for ns2, only some with specific sleep models or sleep schedulings for specific protocols...
