LTE scheduler type

[Yared Zerihun]

Hello there,
what exactly is the scheduler,

lteHelper->SetSchedulerType ("ns3::FdMtFfMacScheduler") // FD-MT scheduler;

Is it a combination of the Proportional Fair Scheduler in Time Domain and the Maximum Throughput in Frequency Domain?

Thank you.

Hi,

Please study the documentation. 

For more information on those specific schedulers I would recommend the GSOC 2012 project

Hello Konstantinos,  I've looked at the link you gave me.

I understood that Round Robin and Proportional Fair Scheduler had already been implemented before the GSOC2012 project started. and they were implementing the other schedulers(MT, BET, TTA) right after. If I am correct in my understanding, I hope the project is already finished by now, LENA has all the main schedulers implemented in NS-3, and my question is:

Is,

lteHelper->SetSchedulerType ("ns3::PssFfMacScheduler");     //PSS scheduler, 

the Proportional Fair(PF) scheduler? If not, where is it or is not it implemented already? 

Can I have a detailed explanation of the implemented schedulers other than the one presented here:
https://www.nsnam.org/docs/models/html/lte-user.html#configure-lte-mac-scheduler ?

Yes the project is finished and those schedulers are integrated. 

 

and my question is:

Is,

lteHelper->SetSchedulerType ("ns3::PssFfMacScheduler");     //PSS scheduler, 

the Proportional Fair(PF) scheduler? 

No, it is not the PF scheduler, it is the PSS scheduler.

 

If not, where is it or is not it implemented already? 

The PF scheduler is implemented and it is the PfFfMacScheduler

 

Can I have a detailed explanation of the implemented schedulers other than the one presented here:
https://www.nsnam.org/docs/models/html/lte-user.html#configure-lte-mac-scheduler ?

https://www.nsnam.org/docs/models/html/lte-design.html#the-femtoforum-mac-scheduler-interface

and 

https://www.nsnam.org/docs/doxygen/classns3_1_1_ff_mac_scheduler.html 

this is the base class and you can see all the derived schedulers implemented.

I used the code:

   Ptr<LteHelper> LteObjeto = CreateObject<LteHelper> ();

   LteObjeto->SetSchedulerType ("ns3::TdMtFfMacScheduler"); // TD-MT scheduler 

But does not work, someone has a code example of changing the escalondor. The video streamming never reaches the destination when I change the scheduler.

Hi Alexandre,

What does not work? 

If you do not change the scheduler to TD-MT, does it work?

If the 'video streaming' does not reach the destination, you might have other issues such as routing.
