I try to understand and implement modifications to the Veins framework. Right now, I have some difficulties figuring out how the "Mapping" structure works. It is used to set the transmission power in "Mac1609_4.cc"

ConstMapping* txPowerMapping = createSingleFrequencyMapping(start, end, frequency, 5.0e6, power)

and to calculate received power, SNR and SINR in "Decider80211p.cc". Could you give some insight and some examples related to the structure manipulation?

The mapping structure is from MiXiM, as Veins initially forked that project. MiXiM, however, is deprecated now and should not be used anymore [2]. Unfortunately, there is no real documentation available (anymore).

As replacement, there is either INET, which also is supported by Veins, or, as it will be introduced in the next release, a much simpler representation of Signals, removing the Mapping structure [4].

If you still need to understand the structure, you can have a look at this paper where the authors explained the physical layer including the Mapping structure.
