Enable RTS/CTS?

[Larissa Eglem]

Hi all,

I'm trying to set a ad-hoc network that uses RTS/CTS. I configured my script as follows:

UintegerValue ctsThr = 500;

Config::SetDefault ("ns3::WifiRemoteStationManager::RtsCtsThreshold", ctsThr);

But I believe the RTS/CTS is not being exchanged.

While enabling all log levels from ns3::MacLow I get this line (partial):

1.026s [mac=00:00:00:00:00:02] MacLow:StartTransmission(0x91d3760, 0x91f2098, 0x91d3ab8, [send rts=0, next size=0, dur=+0.0ns, ack=none], 0x91d3b10)

Shouldn't the field 'rts' in MacLow::StartTransmission be different from zero?

And while debbuging my code I noticed the method MacLow::SendRtsForPacket is never called, instead it goes directly to MacLow::SendDataPacket.

Am I setting my script wrong?

Thank you for any help.

Best regards,

Larissa.

 

[pedro chaparro]

maybe RTS/CTS is not enable, this is some old post, i hope it help u

You will just increase the threshold for 'enabling' RTS/CTS.

e.g. if you set the "rtslimit" to 1000 any packet less than this limit will be transmitted without RTS/CTS.

  Config::SetDefault ("ns3::WifiRemoteStationManager::RtsCtsThreshold", StringValue (rtslimit));

So, if I set the RtsCtsThreshold to zero, all packets should be sent with RTS/CTS right?

[Larissa Marinho Eglem de Oliveira]

I tried to set the threshold to zero, but I'm still having the same problem.

Larissa, just to check, did you place the call to Config::SetDefault before any wifi device is created?
Besides, I think UintegerValue should be used instead of StringValue.
Can you please try this and let us know?

[Larissa Marinho Eglem de Oliveira]

HI,

Thank you Nicola for your help. I have placed the call to Config::SetDefault after the creation of the wifi devices, although I have two calls for Config::SetDefault, since I'm using two wifi devices. In the first wifi channel I want RTS/CTS to be enabled, but not in the second channel.

I have also replaced StringValue to UintegerValue.

It still doesn't work. This is my script:

int main(int argc, char *argv[])

{

FILE *top;

std::string phyMode("DsssRate1Mbps");

std::string phyintervalMode("DsssRate1Mbps");

//package size in bytes

uint32_t packetSize = 1000;

bool verbose = false;

double px,py;

int quantNo;

int quantEnlace;

//in line command arguments

CommandLine cmd;

cmd.AddValue("phyMode","Wifi Phy Mode", phyMode);

cmd.AddValue("packetSize","Size of the packet to be sent", packetSize);

cmd.AddValue("verbose","Turn on all WifiNetDevice log components", verbose);

cmd.Parse(argc, argv);

Hi, 

One more question, why can't I set the RTS/CTS like this:

wifi.SetRemoteStationManager ("ns3::WifiRemoteStationManager", "RtsCtsThreshold",UintegerValue(ctsThr)); 

I get the following error:

msg="Requested constructor for ns3::WifiRemoteStationManager but it does not have one.", file=../src/core/model/type-id.cc, line=198

 Thank you!

Hi Larissa, you succeeded?

Thanks!

[Larissa Marinho Eglem de Oliveira]

Yes! Thank you for asking! I actually placed the first call to Config::SetDefault before creating the nodes, and it's working now!

Thanks!

}

Although the last part regarding flow monitor isn't working properly. I only get the flows from the 10.1.1.0 network. I also need the 192.1.1.0 network. If you have any idea on how to fix that I would appreciate a lot.

[Vitor Carvalho]

Yeah, I do not have this modules (dispatch-module.h and myonoff-application.h).
Do you know how can I see in the logs or in the "real time" output, where was set Rts?

Thanks

[Larissa Marinho Eglem de Oliveira]

You can erase these modules and all the code regarding the second network :)

You can see the RTS/CTS in a trace file, for example in my code: 

//Enables the creation of packet tracking files

AsciiTraceHelper ascii;

wifiPhy.EnableAsciiAll(ascii.CreateFileStream("teste1.tr"));

If you open teste1.tr you'll be able to see lots of RTS, CTS and RTS.

You can also enable the logging in MacLow:

export 'NS_LOG=MacLow=level_all|prefix_func|prefix_time'

./waf --run ...

But all you really have to do is place the Config::SetDefault in the right place.
