OLSR
Optimized Link State Routing (OLSR) is a proactive routing protocol designed specifically for mobile ad hoc networks (MANETs). It enables dynamic routing within wireless mesh networks by maintaining updated routing tables with the most efficient paths between nodes. OLSR optimizes communication by minimizing overhead and quickly adapting to changes in network topology..
Technical Details
Optimized Link State Routing (OLSR) is a link-state, proactive routing protocol primarily used in wireless ad hoc networks, including mesh networks and MANETs. Unlike reactive protocols, OLSR constantly exchanges topology information with other nodes, ensuring all routers have an updated view of the network to establish routes instantly without route discovery delays.
OLSR reduces the size of control messages by utilizing a unique technique called MultiPoint Relays (MPRs). These MPRs are selected nodes responsible for forwarding broadcast messages during the flooding process, significantly reducing redundant retransmissions and conserving bandwidth. This makes OLSR highly scalable and efficient in dense networks.
OLSR operates over IPv4 and IPv6 and relies almost exclusively on UDP (port 698) for communication. Its design caters to the dynamic nature of mobile wireless environments, where frequent topology changes occur. It ensures low-latency route determination, making it well-suited for real-time applications over ad hoc wireless networks.
