[ns] Getting error when running a tcl script after adding a new routing protocol
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

Good day all, I uninstalled and re-installed ns-2.34 but when i try to run some basic tcl scripts it gives an error as " segmentation fault" I did google it on the internet and i didn't find the answer. any one has an idea what is going wrong?

Good evening Ns-users! I just want to ask you how can i measure the transmission rate or the bandwidth of a wireless link between two nodes in NS-2.34 I am using AODV routing protocol. I read that it's possible to get it by using Packet pair But this technique introduces an overhead in the network and i am trying to avoid it. Do anyone have any idea how i can get it?

Going through to aodv_packet.h i noticed there are 5 packet headers (RREQ, HELLO, ERR, RREP_ACK). How can i add my packet header so that i can trace it as well in the trace file?

[ns] CROSS LAYER IN NS2.34: accessing the MAC layer from Routing layer
Good day Dear,
I am trying to access the Mac Layer from the Routing layer of AODV routing
protocol using the following document (see link below). I followed all the
steps but I think i have a problem with the last one, when i try to add the
last step to my tcl script in order to get the right pointer, I am getting
the following error
can't read "rt(0)_o17": no such variable
while executing
"set rt($i)[$node_($i) agent 255]"
("for" body line 5)
..
My question is what rt stands for? is it the AODVagent?
Please see below the link where it is explained
