VLAN implementation using NS2

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..


Steps
Step 1:

Open aodv.h and aodv.cc, 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 aodv.cc file


xpos=ypos=zpos=0.0;

n_speed=0;

energy_t=0.0;

fp=fopen("runtime.dat","w");

Step 4:

add the following statements to the forward() function of aodv.cc

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

t_node=(MobileNode*)(Node::get_node_by_address(index));

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

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

t_node=(MobileNode*)(Node::get_node_by_address(index));

n_speed=((MobileNode*)t_node)->speed();

energy_t=t_node->energy_model()->energy();

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


After the above step,

Step5:

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.

  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.

  7. Hello sir, thanks for your briefly explained tutorial it helps me to know about ns2 simulator as a whole. but when i download your source code of lecture 10 tspagent.cc and myown.tce i get the error.
    $ns myown.tcl
    The error says
    warning: no class variable Agent/PRADEEP::Temperature

    see tcl-object.tcl in tclcl for info about this warning.

    warning: no class variable Agent/PRADEEP::Magnetometer

    ns: puts"message from temperature sensor" : invalid command name "puts"message"
    while executing
    "puts"message from temperature sensor" "
