A core assumption of many network simulators is that interference and noise have a similar impact on the performance of the physical layer. Given the importance of the physical layer model for the realism of the results, it is crucial to make sure that this assumption is correct. And, to be honest, we had our doubts if this is the case.
We, therefore, conducted simulations as well as experiments in an SDR-based testbed. In a nutshell, we found that noise and interference have, indeed, a very similar impact on the performance of the physical layer. Checkout our paper for more details.
In our paper, we compare the impact of noise and interference through both simulations and measurements in an SDR-based testbed.
