Creating script with different traffic types and different periods in IEEE 802.15.6

[rim negra]

I want to generate periodic traffic and emergency traffic for a BAN application, I want to associate the periodic traffic to MAP period and the emergency one to the RAP period. I used the following configuration, after reading your manual.

I specified 6 devices where device 0 is the Hub. I also specified for each sensor, the packet rate and the packet size.

I have the following questions:
1. I'm not able to verify if the transmission is made during MAP period.
2. I do not know how to specify a device with emergency traffic to associate it to RAP period.
3. I specifed the packet size as 17 bytes for node 2, however when checking the result in the trace file, I found it 105 bytes. I attached the trace file to this mail.

Thank for your help

Any answer please?

As far as I remember, 802.15.6 (and certainly the Castalia BaselineBANMAC impementation) does not provide a way to mark specific application packets to be transmitted in RAP (CSMA) or MAP (this is the TDMA choice, right?)

The MAC will try to transmit all any packet in it's data buffer in the first available slot it has. This can be a RAP or a MAP slot.

Dear Dr Boulis,

Using Castalia, is it feasible to implement a method for marking certain application packets to choose between two transmission methods: RAP (CSMA) and MAP (TDMA)?

Nothing has changed with Castalia the last 6-7 years. My reply from all these years back is still the same.

But you can always clone the project and start working on the changes you want yourself. It's not an easy task, but it's an option
