Re: [ns] Ns-users Digest, Vol 44, Issue 24
Hi! I want to work with TDMA protocol in NS-2. But NS-2 documentation doesn't talk much about TDMA implemntation. Can someone give me any links/pointers for a detailed description of this TDMA protocol? Or if you have any source code of your work, which may be help me to develop my methodology.

How can I set in tcl for NS-2 ? Use antennas with different gains. Change the global settings for the antenna gain before you create a node. That means, set it to (for example) to 2dBi for the first 50 nodes and 8dBi for the next 50. Use the propagation.cc utility to calculate the exact parameters (search the list for details). But be aware, the transmission range depends on both, the sender and the receiver. That means, if you have two kinds of nodes (A and B) you get 3 different combinations and hence communication ranges (e.g. A-A: 250m, A-B: 400m, B-B: 500m). Hope this helps, Daniel. -- Dr.-Ing.

For me its seems that you implemented a new propagation model but forgot
to make it available on the tcl layer.
Check the following:
- Makefile compiles your new propagation model
- the final binary contains the new model
- the new model is registered with tcl using the right name

[ns] Movement of nodes should be modifiable during runtime of an ns-2 simulation
Dear all, I'd like to make a simulation with ns-2 where the movement of the nodes is modifiable by another program during the runtime of the ns-2 simulation. How could I realize this? It seems that modifications of trace and movement files are ignored by ns-2 after the files are read in by the TCL script. Thank you very much for your help! Regards, Björn

Hi Bjoern, Schuenemann, Bjoern schrieb: I'd like to make a simulation with ns-2 where the movement of the nodes is modifiable by another program during the runtime of the ns-2 simulation. How could I realize this? It seems that modifications of trace and movement files are ignored by ns-2 after the files are read in by the TCL script I think the problem is that after reading the movement files all events that actually control the movement are already in the event queue. One of my students implemented an external movement control some years ago for the emulation mode. Basically he adds a listening socket that takes simulator control commands from an external program, converts them to TCL code and evaluates them. Then he ran the simulation for an infinite time (and send a stop command from the external controller to exit) and could move the nodes around as he liked. But, this only works in emulation mode. The reason is, if you are in the normal simulation mode, time will jump from event to event. And if there is the last movement event in the queue, the simulator possibly will jump to the final stop event and quit. So, only emulation ensures that your simulation time does not runs too fast. I took a quick look but could not find the diploma thesis / code of the student. I will spend more time searching if you like.

[ns] modified DSR protocol and extract out.tr script

Theoretically if we are using dsr protocol, the route discovery and route maintenance are involved. its also involved RREQ, RREP and RERR.. contain routing table, packet detail information and many more. But regarding to ~tcl/ex/wireless.tcl (using dsr), i didn't find where all this function is calling. It may be a big help if anyone can give your modified ~tcl/ex/wireless.tcl and awk/perl script to extract the ~tcl/ex/out.tr to get some network analysis such as delay/jitter/packet send/received/etc so i can learn from it. your help is valuable for me. thanks..

Re: [ns] Movement of nodes should be modifiable during runtime of an ns-2 simulation
Yes, looked at this issue, and the only way to do it in run-time is to use emulation! If the movement customization did not require run-time, it would be a simple problem - the first program would just generate a movement file according to some parameters.

Re: [ns] segmentation fault
segmentation fault usually stems from illegal access to the memory. check
your code to see whether you illegally try to access some memory when it is
already deallocated. usually it's because using pointers incorrectly.
