EDF protocol

[VIKRAM LODHI]

hi,

i want to apply EDF (earliest deadline first) in ns3.

i have code for EDF but cant apply in code or where to bind it.

i have attached both file

2.-> wifi-mac-queue.cc

thank you

Hi,

you'll need to create anew class derived from WifiMacQueue, subclass the relevant methods (eventually making them virtual in the base class) and modify all the code where the class is used to use 8also) the derived class.

... sorely put: not easy, especially because you posted an EDF example clearly unrelated to ns-3.

let see .. i am gonna try that. 

and one more thing.. 

how can i find packet drop time in a scheduler or packet number?

thanks

PS. go through attached file if you can.

I'll subvert your question: how do you decide what is the deadline of a packet ?

That's the real question.

deadline of a packet is max delay it can take, before getting thrown out of queue.

so i was thinking that , the packet who has waited long in queue should get priority and should be next one for transmission.

[Tommaso Pecorella]

This is the normal concept of priority. To implement an EDF you must be able to assign a deadline time to each packet. How do you know what is the deadline of each packet ?
