  Simulation frameworks are important tools for the analysis and design of
communication networks and protocols, but they can result extremely costly
and/or complex (for the case of very specialized tools), or too naive and
lacking proper features and support (for the case of ad-hoc tools). In this
paper, we present an analysis of three 5G scenarios using 'simmer', a recent R
package for discrete-event simulation that sits between the above two
paradigms. As our results show, it provides a simple yet very powerful syntax,
supporting the efficient simulation of relatively complex scenarios at a low
implementation cost.
