This is the first dynamic routing protocol for ns-3. The implementation is found in the src/routing/olsr directory, and an example script is in examples/simple-point-to-point-olsr.cc.
The following commands will enable OLSR in a simulation.
olsr::EnableAllNodes (); // Start OLSR on all nodes
olsr::EnableNodes(InputIterator begin, InputIterator end); // Start on
// a list of nodes
olsr::EnableNode (Ptr<Node> node); // Start OLSR on "node" only
Once instantiated, the agent can be started with the Start() command, and the OLSR "main interface" can be set with the SetMainInterface() command. A number of protocol constants are defined in olsr-agent-impl.cc.
