[ns] Energy Model

[Mubashir Rehmani]

Hi Ahmed

I will suggest you to create your own energy model. Although it is difficult
but it will be more scalable and will fulfil your needs. To do that i will
suggest you to create a variable in the Node Class per node by declaring it
in Node.cc as energy variable and consume the energy as you want. For
instance, if you want to consume some energy for all the nodes who sends a
packet then firstly give some energy value to the nodes in the constructor
or give random energy values per node. Then each and every node that will
send the packet will consume Rtx energy for transmission of packet. In the
same way, you can also incorporate energy consumption at the reception,
overhearing, mac layer etc

I am suggesting this solution because the whole energy consumption module
will be in your hand and you can easily make amendments as you want in your
energy module.

thanks
