\subsubsection{Simulations for two different inter-clusters network speeds\\}
-
In this section, the experiments compare the behavior of the algorithms running on a
speeder inter-cluster network (N2) and also on a less performant network (N1) respectively defined in the test conditions Table~\ref{tab:02}.
