OLSR: Optimized Link State Routings
OLSR is a proactive routing protocol optimized for Mobile Ad-Hoc Networks (MANETs). It uses an optimized algorithm to flood topology information through the network and provide optimal routes. OLSR is suitable for large and dense networks.
What is OLSR (Optimized Link State Routing)?
OLSR (Optimized Link State Routing) is a proactive link-state routing protocol optimized for mobile ad hoc networks (MANETs). It is designed to work in a completely distributed manner and does not depend on any central entity. The key optimizations OLSR makes compared to classical link state routing are:
- It minimizes the size of control messages and the number of retransmissions needed to flood these messages through the network by using Multipoint Relays (MPR).
- It provides optimal routes to all destinations in terms of number of hops, which is important for battery-operated devices.
- The optimization algorithms used allow OLSR to work well in large and dense networks with many nodes by reducing the control traffic overhead.
OLSR is particularly suitable for large and dense MANETs where the concentration of nodes is high and network topology changes frequently. As it does not require reliable transmission of control messages, it is also suitable for networks where links have high loss rates or connectivity is intermittent.
OLSR (Optimized Link State Routing) Features
Features
- Proactive (table-driven) routing protocol

Pros
Efficient flooding mechanism reduces control overhead
Rapid discovery of new routes after topology changes
Loop-free routes ensured by use of shortest path algorithm
Scales well to large, dense networks
Cons
Constant control overhead regardless of traffic patterns
Higher overhead than on-demand protocols in sparse networks
Relies on periodic HELLO messages - nodes may have stale topology info if messages missed
Security vulnerabilities if not cryptographically protected
