I really need your help . I am beginner with ns-2. I want to elect cluster heads with the residual energy of the nodes within clusters. So I want to get the residual energy of the nodes within clusters in Decideclusterhead() LEACH procedure. (under mannasim , ns-2 module extension)

please give me some advice how should i do if I want to get this parameter.

PS: I have tried , in order to have the residual energy of sensor_ node on leachApp.cc

So I proceeded as follows

1. declare the procedure (on LeachApp.h : double residualEnergy() ) The code on .cc

double LeachApp :: residualEnergy()
{
return ((Battery *) sensor_node_->energy_model())->energy() ;
}

and call it by:

Double E =residualEnergy();
(E is the value of the residual energy)

But I wonder, please, if this is correct, and please , do you have any suggestions that i can use it to have the energy.

looking for your reply soon .
