Finding the Node Position, speed and Velocity of a Node while using AODV

Finding the Node Position, speed and Velocity of a Node while using AODV

Steps
1. ~ns-2.34/aodv/aodv.h
include the following header line in aodv.h

   1: #include<mobilenode.h>
2.In protected scope declare the variables you would be using to store the node parameters.


   1: double xpos;
   2: double ypos;
   3: double zpos;
   4: double iEnergy;
   5: int node_speed;
   6: MobileNode *iNode;
   7: FILE *fp;

3.In aodv.cc initialize the declared variables.



   1: xpos = 0.0;
   2: ypos = 0.0;
   3: zpos = 0.0;
   4: node_speed = 0;
   5: iEnergy=0.0;
   6: fp=fopen("pradeep.csv","w");
   7: MobileNode *iNode;

4.Finally access the required functions from mobilenode.h. Paste the following lines in the AODV::forward() function


//Code by pradeepkumar
/***This code retrieves node 
position*****/
fprintf(fp,"Position is, X, Y, Z, Velocity is, X, Y, Z, 
Velocity, Node Speed, Energy \n");
iNode = (MobileNode*) 
(Node::get_node_by_address(index));
((MobileNode *) 
iNode)->getLoc(&xpos,&ypos,&zpos);
//Position of %d , X, Y, 
Z
fprintf(fp,"%d,%f,%f,%f,", index, xpos, ypos, zpos);
/***This code retrieves the nodes velocity*****/
iNode = (MobileNode*) 
(Node::get_node_by_address(index));
((MobileNode *) 
iNode)->getVelo(&xpos, &ypos, &zpos);
//Velocity of %d , X, Y, 
Z
fprintf(fp,"%d,%f,%f,%f,", index, xpos, ypos, zpos);
/***This code retrieves the nodes speed*****/
iNode = (MobileNode*) 
(Node::get_node_by_address(index));
node_speed = ((MobileNode *) 
iNode)->speed();
iEnergy=iNode->energy_model()->energy();
//Velocity 
of %d , Node Speed in m/s Energy in joules 
fprintf(fp,"%d,%d,%f,", index, 
node_speed,iEnergy);
