\frametitle{Context}
Disseminate data:
\begin{itemize}
\setlength\itemsep{0.8em}
\item Wireless communications
\item Energy constraint
\item Harsh environment
\end{itemize}
\vspace{1cm}
\centering
\textbf{But energy and coverage not deterministic}

\frametitle{Problem}
\textbf{How to choose the right configuration for a given setup?}\\
\vspace{1cm}
Knowing that:\\ \vspace{0.3cm}
\begin{itemize}
\item Perfect coverage not required:
\begin{itemize}
\item Just N+1,...,N+n redundancy (so n network coverage)
\item Collaboration of n nodes (say 3 to monitor some metrics)
\end{itemize}
\item Clear nodes energy budget
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Problem}
Knowing:
\begin{itemize}
\item Nodes setup:
\begin{itemize}
\item LoRa/NbIoT?
\item Uptimes duration 60s/180s?
\end{itemize}
\item Requirements:
\begin{itemize}
\item Nodes energy consumption
\item Network coverage
\end{itemize}
\end{itemize}
\vspace{1cm}
\centering
\textbf{How can we predict which policy to use to meet the requirements?}
\end{frame}
\begin{frame}
\frametitle{Solution}
\begin{centering}
\textbf{Use classification models!}
\end{centering}\\ \vspace{1cm}
We choose:
\begin{itemize}
\item K Nearrest Neighbours
\item Decision Trees
\end{itemize}

Two ML training approaches:
\begin{itemize}
\item Offline
\item Online
