It employs periodic exchange of messages to maintain topology information of the network at each node. OLSR is an optimization over a pure link state protocol as it compacts the size of information sent in the messages, and furthermore, reduces the number of retransmissions to flood these messages in an entire network.
For this purpose, the protocol uses the multipoint relaying technique to efficiently and economically flood its control messages. It provides optimal routes in terms of number of hops, which are immediately available when needed. The proposed protocol is best suitable for large and dense ad hoc networks.

The usage pattern is the one of all the Internet routing protocols. The following sample commands will enable OLSR in a simulation using this helper class along with some other routing helper objects. If the user does not specify a main address, the protocol will select the first primary IP address that it finds, starting first the loopback interface and then the next non-loopback interface found, in order of Ipv4 interface index.
The loopback address of In addition, a number of protocol constants are defined in olsr-routing-protocol. Note: a patch to allow the user to start and stop the protocol at other times would be welcome. However, many other examples esists in the general examples directory, e.
A helper class for OLSR has been written. In addition, the behavior of OLSR can be modified by changing certain attributes. Other parameters are defined as macros in olsr-routing-protocol.
