Good afternoon Ns-users!
I am trying to implement ETX (Expected Transmission Count) and IBETX
(Interference Bandwidth adjusted ETX) as routing metric into the AODV
routing protocol and DSDV routing protocol respectively in NS-2.34. I
created another identical AODV and DSVD ad hoc routing protocols file and I
made some changes into AODV and DSDV file in order to incorporate ETX and
IBETX as routing metric respectively. After that i renamed all AODV and DSDV
files (.cc & .h) to AODVETX and DSDVIBETX files (.cc & .h). I have changed
all the words where the aodv and dsdv words appear by aodvetx and dsdvibetx
words (c++ Classes, Packets headers, variables, TCL bindings,..). After run
"Make clean and "Make" it compiles fine. But during execution of tcl file
with new protocol code I am getting following errors. I have carefully
implemented code step by step by thoroughly reading ns material on internet
and ebooks. I shall be highly thankful to you
