hi , how did you control your data rate in your TCL file?
I used Mac/802_11 set dataRate_ 1.0e6 to control but, it seems not working
By Default the data rate will be 11 mbps.you can see the effect in trace file. Data rate is the bandwidth ,basic rate is the data transferratecommand : Mac/802_11 set dataRate_ 11Mb Mac/802_11 set basicRate_ 2Mb
(I'm not good at speaking English Please forgive my bad English)Why basicRate_ need to set 2Mb, and how do i know what value should i set when i want to set another dataRate_?I read mac-802_11.cc at line #1247 to #1260 if(dst != MAC_BROADCAST) { /* store data tx time for unicast packets */ ch->txtime() = txtime(ch->size(), dataRate_); dh->dh_duration = usec(txtime(phymib_.getACKlen(), basicRate_) + phymib_.getSIFS()); } else { /* store data tx time for broadcast packets (see 9.6) */ ch->txtime() = txtime(ch->size(), basicRate_); dh->dh_duration = 0; }Does it means broadcast use basicRate_ and unicast use dataRate_ ?Thank you for your response :)

command :
Mac/802_11 set dataRate_ 11Mb
Mac/802_11 set basicRate_ 2Mb

I read mac-802_11.cc at line #1247 to #1260
if(dst != MAC_BROADCAST) {
/* store data tx time for unicast packets */
ch->txtime() = txtime(ch->size(), dataRate_);
dh->dh_duration = usec(txtime(phymib_.getACKlen(), basicRate_)
+ phymib_.getSIFS());
} else {
/* store data tx time for broadcast packets (see 9.6) */
ch->txtime() = txtime(ch->size(), basicRate_);
dh->dh_duration = 0;
}
Does it means broadcast use basicRate_ and unicast use dataRate_ ?
Thank you for your response :)
