  Through massive deployment of additional small cell infrastructure, Dense
Small cell Networks (DSNs) are expected to help meet the foreseen increase in
traffic demand on cellular networks. Performance assessment of architectural
and protocol solutions tailored to DSNs will require system and network level
simulators that can appropriately model the complex interference environment
found in those networks. This paper identifies the main features of DSN
simulators, and guides the reader in the selection of an appropriate simulator
for their desired investigations. We extend our discussion with a comparison of
representative DSN simulators.
