Re: [ns] Broadcasting a UDP ns2.34 802.11Ext
Hi Paulo, Sorry to bother you, but I have just seen your question and I have a similar problem: I would like a source node (n0) to broadcast CBR packets via UDP to 1 hop neighbors (n1,n2) in a wireless dhoc network (either CMU 802.11 or 802.11 ext). After if that succeeds, I would like to increase the number of receivers. - Did your solution (i.e., by setting dst_addr_ -2 ) finally work for 40 nodes? - What was your final solution? (if you have a code example) I would really appreciate if you help me with this, Thanks in advance, Best, Behnaz Paulo Robson S. F. wrote: Hi, I want to broadcast a packet using an udp agent. I found some solutions at this maillist but neither satisfactory. I just want to send broadcast packet from 1 node to another 2 nodes in his range. My idea was change the dst ip to -1 and dst port to 0 because i saw somewhere that is the way to broadcast. I'm using the 802.11Ext model of MAC, the new module of the NS 2.34 Well, I made this way: set udp0 [new Agent/UDP] $ns attach-agent $node $udp0 set cbr2 [new Application/Traffic/CBR] $cbr2 set packetSize_ 128 $cbr2 set interval_ 0.015 $cbr2 set random_ 1 $cbr2 set maxpkts_ 1000 $cbr2 attach-agent $udp0 #to broadcast i used this: $udp0 set dst_addr_ -1 $udp0 set dst_port_ 0 In the trace file seems to be right, but i dont know if only this change of address and port of destination is indeed a broadcast to all neighbors.

[ns] Classifier at node in ns2
Hi all, In Ns2, the nodes unicast have by default an address classifier and a port classifier. But when we use a ad hoc routing protocol, like AODV and AOMDV, the nodes use the classifiers of these routing protocols. I´m right? Can you confirm my doubt? Thanks in advance E. Reis
[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

Re: [ns] Getting error when running a tcl script after adding a new routing protocol
Hullo Shalom,
You've most probably not gone through all the necessary steps of adding a
new protocol.
Most importantly, you need to modify the Makefile.in file in the ns-2.34
(or your version of ns-2) directory and add all the necessary inclusions,
then run make again to create the right executables for your protocol.
I have also attached a pdf (it was sent by someone on this email thread a
while ago) on the steps involved in implementing a new protocol.
I hope that will help.
Kind regards,
Nicholas Mbonimpa

[ns] one hop Wireless Broadcast of CBR packets
Hello, I would like a source node (n0) to broadcast CBR packets via UDP to 1 hop neighbors (n1,n2) in a wireless dhoc network. I've tried the following solution: One way, could be to attach the source to each destination as below: set udp1 [new Agent/UDP] $ns attach-agent $n0 $udp1 set src1 [new Application/Traffic/CBR] $src1 attach-agent $udp1 set null1 [new Agent/Null] ns attach-agent $n1 $null1 ns attach-agent $n2 $null1 $ns connect $udp1 $null1 $ns at 0.1 $src1 start $ns at 50 finish But in this case the CBR packets are only recieved by node n2. What should I do? Any help would be appreciated.. Thanks, Behnaz

Re: [ns] How to get results in graph using ns-2.34?
you can use awk files to analyse out.tr and then you can get graphs with xgraph command. or LossMonitor : it's more simple and exact than filtering the out.tr, this is a good exemple how to use LossMonitor http://140.116.164.80/~smallko/ns2/wireless-udp-1.htm 2012/11/6 Muhammad Javed javed_u...@yahoo.com Hi, How can i get graph result from tcl file using ns-2.34?
