\subsection {\label{eval-metric}Evaluation Metrics}
\paragraph{}
The set of measures and parameters we used for evaluating our SEES and comparing its performance with that of existing protocols are defined as follows:
\begin{itemize}
\item $F\!N\!D$ (First Node Dead): measures the length of the stable region which is defined as the number of rounds from the beginning of network operation until the first node dies.
\item $L\!N\!D$ (Last Node Dead): represents the length of the network lifetime, which is defined as the number of rounds from the beginning of network operation until the death of the last alive node.
\item $H\!N\!D$ (Half Nodes Dead): indicates the number of rounds from the beginning of network operation until the death of $50\%$ of the network nodes.

\item Number of dead nodes: gives the total number of nodes that have expired with respect to rounds.
\item Lifetime gain: measures the percentage improvement in the network lifetime gained by SEES over the other protocols after the death of $P\%$ of the network nodes. $P$ can be any value from $1$ to $100$
\item Energy gain: measures the percentage of energy saved by SEES when it runs for the same number of rounds as the other
