hi there,
i'm using this patch, and when i installed it i just followed the 10 indicated
steps and it worked properly. The first time i tried to do this i got some
problems and it didn't work, but it was something that i missed... as for me,
i'm not using ns-2.30, it's ns-allinone-2.28 that i'm using.
my problems were after i implemented an admission control algorithm, i
couldn't include any header file to the application(including the header files
i've never changed), donnow why, i tried to avoid the problem...until now i'm
in a deep shit...
hope it will work for u 2 ...
good luck

Sincerely thanks for the responce Sven.
I still have the same error.
I set up the tcl/lan/ns-mac.tcl as follows:
if [TclObject is-class Mac/802_11e] {
Mac/802_11e set delay_ 64us
Mac/802_11e set ifs_ 16us
Mac/802_11e set slotTime_ 16us
Mac/802_11e set cwmin_ 16
Mac/802_11e set cwmax_ 1024
Mac/802_11e set rtxLimit_ 16
Mac/802_11e set bssId_ -1
Mac/802_11e set sifs_ 8us
Mac/802_11e set pifs_ 12us
Mac/802_11e set difs_ 16us
Mac/802_11e set rtxAckLimit_ 1
Mac/802_11e set rtxRtsLimit_ 3
Mac/802_11e set basicRate_ 1Mb ;# set this to 0 if want to use bandwidth_
for
Mac/802_11e set dataRate_ 1Mb ;# both control and data pkts
Mac/802_11e set cfb_ 0 ;# disables CFB
}
Should I follow these steps, step 7 seems to be very problematic
7. mac/wireless-phy.h:
change
enum ChannelStatus {IDLE, RECV, SEND};
to
enum ChannelStatus {IDLE, RECVING, SENDING};
mac/wireless-phy.cc:
replace all occurences of RECV and SEND (by RECVING and SENDING).
8. common/packet.h:
add
#define HDR_MAC802_11E(p) ((hdr_mac802_11e *)hdr_mac::access(p))
9. run ./configure; make clean; make depend; make in your ns directory
10. happy simulating :o) (e.g with the example script
../ns-x/mac/802.11e/multi_udpflows.tcl)
Sincere thanks and regards.
