SINR and Signal power Pr[dBm] calculations in Veins simulations

Question

I need help in the following, Question-1: In veins simulations, how the SINR of a signal is calculated and where its implemented in the code? Question-2: In veins simulations, how the Pr[dBm] of a signal is calculated and where its implemented in the code? Is it the receiver's antenna where the signal is first received? Question-3: Where in the code i can find the decision making process of accepting or rejecting the signal when the signal is received with a certain power that is below of above some threshold? How can we set the threshold/sensitivity level?

thanks in advance,

Best regards, /MM

Answer 1

If you think for a moment about how a physical system behaves, you might end up understanding the folders structure of Veins. A signal arrives at an antenna, if it's too weak (less than sensitivity), it's withdrawn a priori, otherwise it's going to a decoder and there you might have some errors in proportion to the SINR you got.

1. Statistics are generated in Mac1609_4.cc

2. I'm a bit unsure on this, you'll be able to find yourself after reading this.

3. Decision making? Decider80211p.cc (how cool is that?!)

To look after source files, in Omnet++ you could use Ctrl+left click to find in which files something is defined/declared. I'm still studying myself so please verify this information. Let me know in the comments the answer to number 2.
