About:
Olsrd is a daemon that implements the Optimized Link State Routing protocol, a proactive link-state routing mechanism designed specifically for mobile ad-hoc networks. It dynamically discovers routes in multi-hop wireless topologies, adapting to network changes without manual configuration. This makes it a foundational component for building resilient, self-configuring mesh networks.

Key Features:

Implements the OLSR proactive routing protocol
Supports multi-hop routing in dynamic wireless environments
Highly modular architecture with a plugin system
Minimal CPU and memory footprint for embedded devices

Use Cases:

Establishing community and city-wide wireless mesh networks
Providing robust routing for disaster recovery communication systems
Managing routing for mobile ad-hoc networks (MANETs)

Alternatives:

B.A.T.M.A.N. – B.A.T.M.A.N. is another mesh routing protocol, but it operates at Layer 2, whereas OLSR operates at Layer 3.
bird – Bird is a general-purpose routing daemon for Unix-like systems, primarily for traditional wired networks (e.g., BGP, OSPF), not optimized for wireless MANETs.
