Hi everyone,

I want to modify an existing MAC header structure in INET (for example bmac) where the MAC header will contain an additional bit along with the source address, destination address and type. I have to set/reset that bit before transmitting the packet to the receiver, so receiver can make some decision.

Would anyone please suggest me how I can do that in INET?

Thanking you

You can edit the msg file and include the fields that you need, later, in the mac code, you can modify the header size

Hello Alfonso,
Sir, in xmac, the preamble length and MAC header length is same (preamble->setChunkLength(ctrlFrameLength)). So, if i want to modify preamble structure, I have to change header structure the way you mentioned above. Is not it?

Thanking you

It depends where you want the field, for all xmac frames or only for control frames

Sir, I only need additional fields for preamble. In that case, would you suggest where to add that?
