Hi Ricardo,
the obvious answer - the number of events to process is very different.
But why?
First of all, the different propagation models result in different
transmission ranges. And greater transmission range results in a larger
number of nodes receiving an event and hence more processing time

- transmission power is a property of your devicey, but transmission
range is not. It is a result of the combination of transmitter,
receiver, environment, and signal encoding.

you need to install the kernel headers (or the complete kernel sources)

For me its seems that you implemented a new propagation model but forgot
to make it available on the tcl layer.
Check the following:
- Makefile compiles your new propagation model
- the final binary contains the new model
- the new model is registered with tcl using the right name
