A MANET is a multi-hop ad-hoc wireless network where nodes can move arbitrary in the topology. The network has no given infrastructure and can be set up quickly in any environment. The Optimized Link State Routing(OLSR) protocol is a route management protocol for such mobile ad hoc networks. This study presents the work of implementing the OLSR routing protocol. The implementation is done in a modular fashion, allowing for the use of external plugins. Also,this study analyzes certain extensions to the protocol done in relation to the implementation, including Internet connectivity, security and auto-configuration. More technical implementation designs are also covered.
