NettetThe OLSR protocol uses a link-state algorithm to proactively determine the most efficient path between nodes. The key point of OLSR lies in the dynamic Multi-Point Relay (MPR) technique, which selects only a subset of neighboring nodes to relay data instead of every node acting as a relay.

The Link State Routing Algorithm is an interior protocol used by every router to share information or knowledge about the rest of the routers on the network. The link state routing algorithm is distributed by which every router computes its routing table.
