\section{Optimized Link State Routing (OLSR) Module}
|
|
|
|
|
|
OLSR is a proactive routing protocol for mobile ad-hoc networks
|
|
(MANETs). It is well suited to large and dense mobile
|
|
networks, as the optimization achieved using the MPRs works well in
|
|
this context. The larger and more dense a network, the more
|
|
optimization can be achieved as compared to the classic link state
|
|
algorithm. OLSR uses hop-by-hop routing, i.e., each node uses its
|
|
local information to route packets.
|
|
|
|
OLSR is well suited for networks, where the traffic is random and
|
|
sporadic between a larger set of nodes rather than being almost
|
|
exclusively between a small specific set of nodes. As a proactive
|
|
protocol, OLSR is also suitable for scenarios where the communicating
|
|
pairs change over time: no additional control traffic is generated in
|
|
this situation since routes are maintained for all known destinations
|
|
at all times. -- cfr. RFC3626

\subsection{pico\_olsr\_add}
|
|
|
|
\subsubsection*{Description}
|
|
This function will add the target device to the OLSR mechanism on the machine,
|
|
meaning that it will be possible to advertise and collect routing information
|
|
using Optimized Link State Routing protocol, as described in RFC3626, through the
|
|
target device.
|
|
|
|
In order to use multiple devices in the OLSR system, this function needs to be called
|
|
multiple times, once per device.
|
|
|
|
\subsubsection*{Function prototype}
|
|
\texttt{pico\_olsr\_add(struct pico\_device *dev);}
|
|
|
|
\subsubsection*{Parameters}
|
|
\begin{itemize}[noitemsep]
|
|
\item \texttt{dev} - a pointer to a struct \texttt{pico\_device} specifying the target interface.
|
|
\end{itemize}
|
|
|
|
\subsubsection*{Return value}
|
|
0 returned if the device is successfully added.
|
|
|
|
\subsubsection*{Example}
|
|
\begin{verbatim}
|
|
|
|
ret = pico_olsr_add(dev);
|
|
|
|
\end{verbatim}
