[ns] Enqueque packets
Hi NS-users, I want to emulate an udp application using tcl scripts. Since the packets do not have constant size I cannot use CBR. I intented to use a Agent/UDP. the send method and enqueue the packets to the link queue. As far as I understand the docu this can be done with C++ using the enque method. Is it possible to use this method from inside the tcl scripts? To make things clear. I want to send a bursts of udp packets, all packets with different size varing from 10-80bytes. Immediately after packet one I want to send packet two, ..., pause, next burst. I tried to use $ns at 5.0 "$udp send 10 pk1" $ns at 5.0 "$udp send 11 pk2" $ns at 5.0 "$udp send 23 pk1" but in this case all messages will be send at (nearly) the same time... (which is correct, but not what I want) Any advice how to use the queue mechanism or any other "workaround" would be fine.. Thx in advance Raphael

[ns] 802.11g in ns 2.28
Hello all, I would like to implement 802.11g in ns-2.28. I have found many discussions of this on the web such as: http://web.syr.edu/~dchen02/FAQ.txt However, the directions I have found are a little unclear. Some of the variables mentioned such as DSSS_CWMin only occur within files that don't seem to be used in 802.11. Can someone who has done this before give me some advice, or clear up the above mentioned directions? Any help is MUCH appreciated. Will
Re: [ns] ns 2.2x installing problem
Hi ,
I include below information regarding the patching of ns-2.28 for the
new version of the bash obtained from a website a few months back.
-
Hi,
Yeah, I successfully installed ns-allinone-2.29.2 on FC5 but after
slightly modifying the whole package. First, I updated the Tcl and Tk
sources to the 8.4.13 (you can grab a copy from sf.net). Then you'll
have to modify the configure files (Tcl, Tk, OTcl and TclCL) in this way:
cp -v configure{,.orig}
sed "s/relid'/relid/" configure.orig > configure
I hope this information will be useful
Kind Regards,
Sampath

Re: [ns] serialization in ns-2
Hi, I have actually dabbled with the concept of serializing objects for transmission over network in ns2. In my experience serialization of objects for transmission over a network is a complicated process. So instead of actually serializing the object itself I create a serialized version of it the form of a packet. The packet contains all the information required to instantiate the object on the receiving end without actually serializing and encapsulating the object itself. Something similar to below : Object a = new Object; char * sObj = a->serialise(); .. .. Encapsulate sObj inside a packet .. .. send(packet) Hope this helps.
