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.
