Finding Energy, node position and speed in AODV - NS2 Tutorial # 11.1

AODV - Part 2

Finding the node position, energy and speed of the node while it is forwarding a packet.

By default, these codes are not there in AODV, so we are going to modify or append in AODV protocol..

Step 1:

Open aodv.h and, these two files will be modified

Step 2:

Declare variables in aodv.h file in protected mode

double xpos,ypos,zpos,energy_t;

int n_speed;

MobileNode *t_node;

FILE *fp;

Step 3:

initialize these values inside the constrctor of file





Step 4:

add the following statements to the forward() function of

fprintf(fp,"Position is X, Y, Z, Node Speed,Energy\n");


((MobileNode*) t_node)->getLoc(&xpos,&ypos,&zpos);

fprintf(fp,"%d %f %f %f",index,xpos,ypos,zpos);




fprintf(fp,"%d %d %f\n",index,n_speed,energy_t);

After the above step,


recompile ns2 using the command

$] make

Step 6:

run a TCL File and check for the runtime.dat file in the same folder.

$] ns AODV.tcl

You will get a file called as runtime.dat in the same folder.

use the file for plotting any characteristics.

Thanks for watching.

  1. I followed as per your instructions .But I didn't get the values of nodes position and energy from in the same folder where created the AODV.tcl file. when I run AODV.tcl file only get the the nam visualization
    Please hep me.

  2. I am not getting your AODV.tcl file

  3. How could I pass those values from node to neighbor node along with the RREQ/RREP packet?

  4. hello sir, i wanna modify MPR selection based on energy consumption. would you help where to do the modification in the OLSR. thank you. please mail me

  5. Sir,

    While executing the tcl script for find the energy of the nodes. The runtime.dat is not getting created in the folder sir.

    I am using Ubuntu 18.04, So please do suggest me sir.

  6. Sir, I like your videos all you have posted, on this video i didn't get the AODV.tcl file, where I get it? please send me with this address

Ant Colony algorithm using NS2

Ant Colony Algorithm in NS2 for Wired Networks. Please follow the video for full instructions  I am running in Ubuntu 20.04 There are multiple files in Ant Colony (we use a protocol called Antnet) which i have already included in my blog called  Lets go to my Blog. And Search for Ant Colony and Download the complete folder AntNet as shown in the video. Now Copy paste the files in their corresponding location: My Location if ns2 is  /home/pradeepkumar/ns-allinone-2.35/ns-2.35/ Inside this folder, the files have to be pasted in differnet sub folders...  Let me show you one by one... and cmu-trace.h have to be pasted to ~trace/ and drop-tail.h ---- ~queue/ to be replaced in the ns-2.35/ folder. ns-default.tcl, ns-lib.tcl and ns-packet.tcl to be pasted at  ~tcl/lib packet.h to be replaced at common/ folder. and priqueue.h to be pasted at queue/ antnet / folder have to be copied to ns-2.35/ folder (this is very imp
