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.
Thanks in advance.

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.

And I apologize for any inconvenience that this cause. Thank you for everything.

Normally, we add this kind of code in the recv() method for reception: *recv() {* ..... ** * if (ch->direction() == hdr_cmn::UP && ((u_int32_t)ih->daddr() == IP_BROADCAST || ih->daddr() == ra_addr())) { //....do sth. ...* * dmux_->recv(p, 0); return; }* ** *}* ** But it seems that when the NS2 is trying to receive the packet at the destination, the recv() method is never called, and the packet is delivered directly from the MAC layer to AGT layer. And from the trace file I got: r -t 9.799191277 -Hs 1 -Hd 1 -Ni 1 -Nl MAC -Nw --- --Ii 622 -Iv 29 -Pn cbr -Pi 0 -Pf 4 -Po 3 //the mac layer of the destination get the packet r -t 9.799216277 -Hs 1 -Hd 1 -Ni 1 -Nl AGT -Nw --- --Ii 622 -Iv 29 -Pn cbr -Pi 0 -Pf 4 -Po 3 //and pass it to the AGT layer, without passing the RTR layer The situation is the same with DSDV and AODV protocol in NS2. But in DSR, we have: r -t 9.801548775 -Hs 1 -Hd 1 -Ni 1 -Nl MAC -Nw --- - -Ii 0 -Iv 30 -Pn cbr -Pi 0 -Pf 3 -Po 3 r -t 9.801573775 -Hs 1 -Hd 1 -Ni 1 -Nl RTR -Nw --- --Ii 0 -Iv 30 -Pn cbr -Pi 0 -Pf 3 -Po 3 //here the packet is in RTR layer!!! This is what I want r -t 9.801573775 -Hs 1 -Hd 1 -Ni 1 -Nl AGT -Nw --- - -Ii 0 -Iv 30 -Pn cbr -Pi 0 -Pf 3 -Po 3 I try to analyse the differece in the code between the protocols, but have no idea about this problem. Is there anyone know about it? It will really save my ass.... Thank you in advance. Best regards, J.

I have done all this steps that I have found in internet 1- Create a directory "gpsr" with gpsr.cc and gpsr.h in it. 2- Declare gpsr packets in common/packet.h, adding PT_GPSR and in packet.h with name_[PT_GPSR] = "GPSR" 3- The tracing support doesn't need to be implemented right know. 4- In tcl/lib/ns-packet.tcl add "GPSR". Then you'll have to declare all defaults values of gpsr binded attributes in tcl/lib/ns-default.tcl. To do it easily, have a look at the end of the ns-default.tcl file originally used bu gpsr in ns2.1b6. You'll get everything you need. It should look like Agent/GPSR set ..... Copy paste it to your ns-default.tcl file. 5- You have to add procedures to create gpsr nodes in tcl/lib/ns-lib.tcl. You must add in Simulator instproc create-wireless-node args{ .... } the following: GPSR { set ragent [$self create-gpsr-agent $node] } Then, add the pocedure Simulator instproc create-protoname create-gpsr-agent {node} { set ragent [ne Agent/GPSR] $ragent node $node $self at 0.0 "$ragent start" return $ragent } 6- Finally, update the makefile to compile everything by adding the folowin line gpsr/gpsr.o\ However, when I try to compile gpsr.h, I get many errors. Does anybody have the same problems??How can I solucionate it?
