-OLSR stands for Optimized Link State Routing. It was designed for mobile ad hoc networks where nodes form a multi-hop network without fixed infrastructure. Its main idea is to use link-state routing, but more efficiently than classic flooding: it introduces Multipoint Relays (MPRs) so only selected nodes retransmit control traffic, which reduces overhead.+OLSR, or Optimized Link State Routing, is an older open routing protocol for wireless mesh networks. It came out of the mobile ad hoc network (MANET) world, where devices form a network on the fly by connecting directly and relaying traffic for one another without fixed infrastructure. OLSR’s key idea was reducing routing chatter by designating certain nodes as relays, so not every device had to repeat every update.
  
-The tradeoff with OLSR is that it is a fairly full-on routing protocol with regular topology exchange. That makes it important and influential, but also a bit “heavy” compared with newer approaches. OLSRv2 modernized the original design and separates some functions into a more modular architecture. Read [[rfc>3626|RFC 3626]] for more information.+That made OLSR one of the defining early open protocols in the history of mesh networking. It is less modern and efficient than newer options like Babel, but it remains an important example of how decentralized networks learned to keep themselves stitched together. Read [[rfc>3626|RFC 3626]] for more information.
