\section{Introduction}
|
|
\projectname{} is a simulation of a sensors network which makes use of the following stack:
|
|
\begin{itemize}
|
|
\item wireless IEEE 802.15.4
|
|
\item 6LowPAN
|
|
\item IPv6 (routing via RPL)
|
|
\item UDP
|
|
\item CoAP
|
|
\end{itemize}
|
|
|
|
It is developed on Z1 nodes with Contiki OS, and simulated inside Cooja.
|
|
A Java CoAP cache proxy has been developed using Eclipse Californium library, and all CoAP messages are RFC8428 (SenML) compliant.
|
|
The Trickle algorithm used inside RPL has been properly tuned in order to deal with a maximum of 40 wireless nodes randomly and uniformly distributed, and a maximum of 4 hops. % TODO please make sure it really is like this
|
|
|
|
\section{Overview}
|
|
Usage of RPL objective function 0 is mandatory by specification.
|
|
It is designed to find the nearest grounded (ie. connected to external network) root \cite{rfc:rplof0}.
|
|
|
|
\section{Trickle Parameters}
|
|
Depending on the specific network we want to develop, three different goals can be of interest:
|
|
\begin{itemize}
|
|
\item energy consumption
|
|
\item network formation time
|
|
\item network stretch
|
|
\end{itemize}
|
|
|
|
Depending on the most relevant goal for the specific application, the Trickle algorithm used in RPL can be tuned via two parameters:
|
|
\begin{itemize}
|
|
\item $k$
|
|
\item $I_{min}$
|
|
\end{itemize}
|
|
|
|
Since we decided that \$somegoal was more important, and we read mingozzi, %% TODO
|
|
from \cite{bib:mingozzi:tricklef} we can infer that... % TODO infer something please
|
|
|
|
%% ETX expected transmissions %% TODO should we put this somewhere?
