mac packet in matlabcode

Hi,

I am relatively new to MATLAB and I was woundering if it is possible to simulate the MAC layer with QoS of WIMAX 802.16d or e?

Any comments on this metter will be appreciated.

Thank You!
regards!
 

802.16 mac layer simulation model

Hi,

I m not much familiar with WiMAX MAC layer stuff, but u can simulate any wireless systems MAC with or without QoS constraints, with MATLAB. MATLAB gives you very flexible environment to simulate your system mostly if you are working with matrices stuff.

I would suggest you write m-files rather than using the simulink. They are easier to change and maintain
 

mac layer source code

For full simulation of MAC level, i think, it should be better to write a simulation program on C or C++, because there are a lot of structures, like a QoS parameters, Service Flows parameters, MAC management packet's data etc. As for me, it's too difficult to implement pointers, structures and arrays of structures in Matlab.

By the way, if you only need to simulate scheduling algorithms, you could use Matlab.

For my opinion, the better type of scheduling for UGS and rtPS traffic is EDF algorithm, and for nrtPS and BE traffic - WFQ algorithm.

Thank you all for the reply. It gave me the directions.

Ragards!
 

design wimax by matlab

Hi,

Thanx again on the replay. I would like to discuss something as well with you if you dont mind.

I am supposed to design the model for WiMAX 802.16d for physical and possible MAC layer using MATLAB. I had a look on differnt materials on MathsWork website.
I was woundering whether MATLAB or Simulink is better in simulating the physical layer? I personaly think that MATLAB m-file offers higher flexibility compared to Simulink in physical layer design.

Any comments on this metter will be appreciated.

Thank you
Regards
 

smartbits mac layer

For PHY simulation, it is better to use both Matlab and Simulink, because Matlab will help you with randomizer and interleaver (you sould write some m scripts) and you can use Simulink with RS and CC blocks (but i didn't use Simulink).
 

code matlab of mac layer

Who could tell me detail about scheduling services that WiMax defines?
I know that there are 5 scheduling services : UGS. rtPS, nrtPS, BE and ErtPS (Extended real-time polling service. But it is really difficult for me.
 

matlab code simulating wimax

Hi,
Smart bits, Vector signal Analyzer for MAC analysis, & Layer 1 are the softwares used

Could you tell me about EDF and WFQ algorithm, plz?
 

mac layer in simulink

For more detailed descriptions of EDF and WFQ algorithms you should read the following book - "Scheduling in Real-Time Systems" by Francis Cottet, Joelle Delacroix, Claude Kaiser, Zoubir Mammeri.

One useful practical exapmle of using WFQ algorithm is described in a book named "Inside Cisco IOS", but, unfortunately, i can't remember the name of author.

Basically, EDF algorithm is based on timing properties of connection, so we should use this type of algorithm for scheduling connections with real-time data.

When the timing properties aren't so important, but we need to schedule several connections with diffrent amounts of data, we use the WFQ algorithm, because it gives the queue's grants, which depending of data size in queue.
 

wimax mac layer testing type

no ways man...
no ay u can implement wimax MAC on matlab ...
there are too many functional modules, sub-modules, modular functions, supporting functions too much of memory constraints, handling pointers, structures, enumerators are difficult in MATLAB ...
 

wimax mac matlab simulation

Hi,
If anybody have matlab simulation code of Physical layer of wimax, please uoload it.

Any help will be highly appreciated !!

Thanks
 

matlab code wimax physical layer

You can found a Matlab simulator in the Mathworks site.
I will attach the code.

WiMAX Physical and MAC Layer

Description Matlab source code for the test vectors and Simulink model for physical layer with MAC Layer addition to the previous model. This model is based on Physical Layer Specification of IEEE 802.16e and ETSI HiperMAN. Run Data.m to copy data to workspace and then run the WiMAX_Test_4.mdl model.

hey it seems the previous code is only for the phy layer....can any one give the codes of mac layer...
 

Hello everyone,
I'm also looking for mac layer at wimax but mesh networks. can anyone here help me?
regards,
V K
 

Hi vini_rathi,
Good day.

Hope you are fine. Are you found any code in mesh mode? Then please send me this email: farhad.ramim@gmail.com. Any help would be greatly appreciated. Thank you.
