[ns] BitTorrent sources
Hi all, Would anybody please send me a BitTorrent source code and scripts for NS-2 (like the Kolja Eger's patch) to help my research? The Eger's patch isn't avaliable anymore in the cited link.

[ns] getting link queue class prob
hi to all
well these are problems i m facing now
i was trying to get nos of bytes currently contain in a Que
after searching i have found that queue class contain a packetqueue object
that have a protected variable "bytes_"
i have done this to get a queue handle
set queulimt [[[$ns link $node $nbr ] set queue_] set limit_]
it gives me max nos of packet queue can contain
i found no way to communicate the queue class in c++
and finds out that queue doesnt have any command funtion
then i turn back to droptail queue classs and find out that it contain a
command function and also contain base class queue::command();
but i havent found any implementation of queue::command()
further more when i try to write my own command funtion in existing queue
base class it gives an errror of unknown split object
then i done this ,
set queu [[[$ns link $node $nbr ] set queue_]
then i took the refrence back to my c++ code
there i done this
Queue *q;
q=argv[9] /// as it comes at postion 9
q->byteLength();
it gives a segmentation fault error
then i tries to create a bind object like
this
bind("byte_", tmpq);
and in tcl i set it with queu handle
$self set byte_ $queue
and in c++
tmpq=(Queue*)bytes_;
Tcl::instance().evalf("puts \"bytes %d\"",tmpq->byteLength());
output was 0 at that time
do you have any other idea about this
[ns] TORA simulation does not come to an end in ns2.34
Hello, I have successfully changed and configured TORA in ns-2.34 (in fedora 9), as learnt from http://www.gidforums.com/t-19724.html. Now, when I run the simulation, it stops at a point and does not finish. If the simulation time is 20 seconds, it do completes but for simulation times more than 20 seconds, it never comes to an end; num_nodes is set 3 INITIALIZE THE LIST xListHead channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 SORTING LISTS ...DONE!

[ns] problem with dumbagent as routing protocol
Hi.. I'm using DumbAgent as routing protocol in my wireless ad hoc network to check on 802.11b RTS/CTS operations. My question, by using the DumbAgent, will the data packet actually arrived at the destination? My problem is, my data packets keep dropping at the sender even when the sender and the receiver are close to each other (within the transmission range). When I changed my rp to AODV/DSR, I have no problem with the transmission. But when I revert back to DumbAgent, the receiver never receive any of the data packets. Is this normal or did I do something wrong? Any insight will be very much appreciated. Thank you again in advance regards Aslinda Hassan Computer Engineering Research Lab Faculty of Engineering and Applied Science Memorial University of Newfoundland

Re: [ns] Exactly moment of reaching destination
Larissa Lucena wrote: > Scheduler::instance().clock(), <- this is the actual simulation time You have to check somehow by your own code , when the destination is reached. The node has to know the destination coordinates. You have to check if the actual position is the destination position. If it is reached you can record the simulator time. -- View this message in context: http://old.nabble.com/Exactly-moment-of-reaching-destination-tp27905332p27907839.html Sent from the ns-users mailing list archive at Nabble.com.

[ns] Exactly moment of reaching destination
Hi, Guys!
I'd like to know the exactly moment that a mobile node reaches its
destination position. I've read and read so many time the method

I need this to send a packet exactly in that moment. Could anyone help me?
Thanks again!

1. "class MobileNode" is derived from "class Node" it has also the method
"get_node_by_address()".
2. MobileNode* tmnode = (MobileNode*)srcnode; -> don't cast from one class
to another this is no good code . you will have problems!
3. you have created your own "struct mobileNode" - don't mix it up with the
"class MobileNode"
4. error1 : "inclompete type" -> you missed something to write to your code.
maybe "{" , "}" or ";" ?
5. error2 : "forward declaration" -> wrong place in the file where your
struct is declared
my advice : you are a beginner in programming , please learn some general
things about c/c++ programming . look at some tutorials or homepages with
examples, e.g. http://www.cplusplus.com

[ns] transmission delay
Dear all, How is a packet transmission delay modeled in NS2? I mean which construct makes sure that a packet would be transmitted. If I want to transmit an additional packet, how should I do that? Should I add a new packet type and declare its length etc? Please let me know if you are familiar with it. Thanks, Sireesha.
