communications are not slowed down, because there is no contention yet).
As an alternative to the above LMM-based models, it is possible to use the :ref:`ns-3 simulator as a network model <models_ns3>`. ns-3 performs
-a mushc more detailed, packet-level simulation
+a much more detailed, packet-level simulation
than the above models. As a result is is much slower but will produce more accurate results.
Both simulators have time complexity that is linear in the size of their input, but ns-3 has a much larger input in case of large communications
because it considers individual network packets.
