Computation Overhead

[Smach Meriem]

Dear Ns3 users,

 I want to calculate Computation OverHead in my network. Did any one have any idea???

I would be very grateful if you could help me.

Thanks in advance.

Hi,

it has been discussed many times before. Please take a look at the groups. And the answer is no, you can't calculate it.

Dear Meriem,

Please define what you mean with computation overhead and in what context.

Computation overhead is so broad like saying wireless communications. It covers everything.

Dear Sir Konstantinos,

 In my use case, I want to test if  when I have many smart meters (each smart meter is represented such as a mesh Client) that want to send data to a mesh router ( which is responsable to collect all the data) in the same time. So i want  to simulate their computation in sending their data.  I hope That my idea is clear now.

Thank you very much sir.

Dear Sir Tomasso,

I find in some research such communication protocol in smart grid that there is a simulation for the computation overhead. SO, i Think that i can calculate it.

Thank you very much sir

Computational overhead is the time needed by a node to process a packet. It should be calculated from the time the packet has been fully received to the time the node has finished processing it. Eventually, after this time the node could have another packet ready to be sent.

We explained the topic of computation overhead too many times in this group.

I don't have any willingness to explain it again, especially to someone that shows no interest in reading what has been already extensively discussed.

If, by chance, your definition of computational overhead doesn't match the above one, please double check what you write before sending. Being precise is what differentiates a tech. from a [fill in].

Good luck,

T.

Hi

As Tomasso suggested you can't calculate it unless you have a model for it which is will be very specific to the architecture of that node.

For example, the computation time for an Intel i7 @ 3GHz that you have on you laptop is not the same as that of the micro-controller that you can find on those smart meters.

And smart-meter from smart-meter may have different computing power and may experience different load. 

That's why you can't calculate it.

Now you said you have found some papers that say that they do calculate it. Study those papers to understand how they actually do it. Do they simulate it or do they use real systems? If they simulate it, what are their assumptions/model?

Regards,

K.
