The mobile ad hoc network is one of the most emerging technologies in the present scenario. Enormous progress and development has been done in this area and much more needs to be done yet. Several protocols are present for MANET. Many of them are being used so far very efficiently. Optimal Link State Routing Protocol is one of them. It is the proactive table driven routing protocol that is it shares the information periodically with its neighbor. However to avoid the flooding, OLSR chooses Multipoint Relays. These MPRs are selected nodes in the network to which packets will be forwarded for further transmission.
