TMAC problem

i just change the code in file which is MAC to MAC/TMAC and this problem occur

num_nodes is set 10
can't read "val(tmac)": no such element in array
while executing
"$ns_ node-config -adhocRouting $val(rp) \
-llType $val(ll) \
-macType $val(tmac) \
-ifqType $val(ifq) \
-ifqLen $val(ifqlen) \
-antType $val..."
(file "tmac.tcl" line 39)

Please explain how you edited ns2 to do "tmac" :
No tmac, TMac, Tmac, TMAC is included by default.

i just edit the infra.tcl file inside the 802.11 folder

If you have read any of the answers here https://www.linuxquestions.org/quest...s2-4175664649/
... or some ns2 simulation files, you will know that a mac protocol is not entered this way:
-macType $val(tmac)
But with :

set val(mac)    Mac/TMac          ;# MAC type

Besides that, a protocols needs to be added to the simulator, like this

ns2/
├── mac/
│   ├── tmac.cc 
│   ├── tmac.h
├── common/
│   └── packet.h
├── Makefile.in
└── tcl/
    └── lib/
        ├── ns-default.tcl
        ├── ns-mobilenode.tcl
        └── ns-packet.tcl

What we know is that the AquaSim "underwatersensor/uw_mac/{tmac.cc, tmac.h}"
.. were edited from the original "TMAC time out mac {tmac.cc, tmac.h}"
.. to do also the underwater stuff.
?May be you can edit the AquaSim {tmac.cc, tmac.h} to work without the uw functions?
