Unexpected increase of packet loss rate when more RBs available #203

Closed zazim13 closed 6 months ago

zazim13 commented 7 months ago

Hello there,

I've been encountering unexpected performance issues with my simulations. I have implemented both a MecApp and a UEApp and I am generating traffic from an UE. I've noticed that as I increase the number of resource blocks (numBands) available, I'm unexpectedly experiencing greater packet loss. While the end-to-end delay decreases(as expected), the rate of packet loss increases.

Additionally, I have observed that my SINR decreases with more resource blocks available. Especially, I observed a fading attenuation 10 times higher when I increase from 200 RBs to 2000 RBs available accompanied by a rise in packet loss rate.

This trend seems counterintuitive to me. I can give more details if needed.

Kind regards Hakim
