Simulation Results of the OLSR Routing Protocol for Wireless Network
Anis Laouti, Paul Mühlethaler, Abdellah Najid, Epiphane Plakoo · 2002
In this paper, we present simulation results for the Optimized Link State Routing protocol: "OLSR". "OLSR" is a routing protocol currently submitted at the IETF in the Mobile Ad-hoc NETwork workgroup. "OLSR" is a proactive protocol, thus it periodically sends "control" packets to build and update the topology. The aim of this article is to study the performance of the OLSR protocol. Although most of the results that we show remain valid for any kind of above medium access control and physical layer, the simulation results were obtained with an IEEE 802.11 medium access control and physical layer. The key parameters that we evaluate in this article, include: the overhead incurred by the routing protocol, the percentage of packets lost in the control packets and the lack of routes due to control packet loss. We also study the benefit of a genuine optimization of the "OLSR" protocol: the multipoint relay optimization and the OLSR's capability to support mobility. Another important goal of this article is to deeply understand in the presented simulations the behaviour of each network layer: the OLSR routing layer, the MAC and physical layer as the possible interactions between them.
