You might need to find a tutorial to learn something basic. You can refer to "Implementing a New Manet Unicast Routing Protocol in NS2" Francisco J. Ros Pedro M. Ruiz Or http://blog.chinaunix.net/u/10654/showart.php?id=52030 http://140.116.72.80/~smallko/ns2/ns2.htm (need to un

[ns] How to access mac layer of each node

Hi, all How to access mac layer of each node? If I create a command “attach-traceDebug” in mac-802_11.cc to transmit debug file name to it. How could I call this command in tcl script. Like “set ftp [new Application/FTP], $ftp attach-agent $tcp”, what should be the first par

Re: [ns] Simulating channel Hopping in ns2

he C++ part of the code it is always a very good idea to run ns-2 using valgrind. Simulations will use a lot more time to run, but every strange or wrong memory access will be recognized. Daniel.

Re: [ns] Compilation Error ns2.1b8a

TCL_H > -DHAVE_LIBTK8_3 -DHAVE_TK_H -DHAVE_LIBTCL8_3 -DHAVE_TCL_H -DHAVE_CONFIG_H > -I. -I/bonhome/haseeb/work/ns-allinone-2.1b8a/tclcl-1.0b11 You should provide more information, especially the version of gcc/g++ you are using. NS2.1b8a is very old. So, you will need an old gcc / binutils to compile it. Daniel.

Re: [ns] How can i measure the bandwidth in use?

ends in the output buffer of the transmitter. Changes in this time indicate a change in the available air time. You see, the task you are going to solve cannot simply be accomplished by calculating a value out of available variables. If you have more questions, don't hesitate to ask me. Daniel.

Re: [ns] Need tunctl command for cygwin

is configured in a different way. If you are using the nse extension for wireless emulation you should give up on Cygwin, you have to run it on Linux. But it is possible to integrate Windows clients in such a setup. Daniel.

Re: [ns] Shadowing model

roblem? > I tried to change de seed for each iteration, but it didn't work > I used the following code and it worked: $defaultRNG seed $seed set ns_[new Simulator] I think it is important to initialize the seed before you create the Simulator object. Daniel.

Re: [ns] Multiple source files

igures the applications and runs the simulation. Now, in order to investigate different topologies, I wrote a control script, that iterates over the list of available toplogies and calls the simulation script with the name of the topology script as a parameter. You should be able to do something similar. Daniel.

Re: [ns] CBQ with wireless network: Nobody Replied Yet

s communication uses broadcast transmissions over the wireless channel object. So, using link-based queuing will not yield any useful results. Daniel.

Re: [ns] Shadowing propagation model problem with NS 2.29

is distance is. So the shadowing model returns a nearly infinite value. Of course this could be optimized. Daniel.
