TDMA in wave

[Nyoman Wira Prasetya]

Hi,

Wave model comes with OFDM and i want to use TDMA in wave.
Can anybody help me by giving suggestion how to do it?
Thank you very much for your help.

I'm not sure I understand the question.  Perhaps you can explain more about what you are trying to achieve, and what you have tried.

OFDM is a way to encode the bits for transmission at the PHY layer.  TDMA is a way to access the channel (in time slices).

If you are looking for examples of how to support channel switching in WAVE, then please check wave/examples/wave-simple-device.cc, especially WaveNetDeviceExample::SendWsmExample() and SendWsaExample()?  That should alternate between CCH (first half of interval) and SCH1 (second half of interval), and there are also examples for continuous channel access.  From those examples, I think you can determine how to set up your own TDMA scheme.

Thank you Scoot,
What i'm trying to achieve is do a VANET mobility simulation using TDMA system.
WAVE come with only OFDM i thought it will effecting PHY layer and MAC if i change it into TDMA.
Right now i'm studying TDMA from https://groups.google.com/forum/#!topic/ns-3-users/5w60gWAd4WI as a start point.
I will do your suggestion too.
Thank you very much

Dear Nyoman,

actually I am doing and implementing the TDMA for VANET as well. If you like we can have share information to each other.
