Hello,

I  extract the position and speed of vehicles using this code:

fprintf(fp,"Node , Position is X, Y, Z, Speed \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();
fprintf(fp,"%d %d \n",index,n_speed);

and put it in an external file.
But, in this external file does not appear all the vehicles of the network.
for example: my network consists of 5 vehicles but the external file shows
only 4 vehicles and sometimes (3 vehicles).
Can someone tell me why all vehicles do not appear in the external file and
help me fix this problem?
Is it dependent on the range transmission of each vehicle?
Can somebody help me please.

Thank you in advance.
