Propagation Models for Next Generation Networks in NS-3:A Survey
Simulations of mobile radio systems require propagation models for determining the channel characteristics for a given arbitrary scenario. Propagation path loss models can be used to predict wireless channel characteristics like received signal strength, multipath effects, and interference. These predictions are an important aspect of simulation of wireless networks and aid in the high-level network planning process. Various models are available for modeling propagation characteristics and they vary in terms of both modeling performance and computational complexity.
