Performance model of flooding in OLSR

OLSR is one of the most well developed routing protocols for MANETs. OLSR as a link state routing protocol relies on its flooding mechanism to disseminate topology information to all nodes in the network. However, the performance of the flooding algorithm is poorly understood. In this paper models of key performance metrics of this algorithm are presented. Specifically, it describes a model for the control overhead generated by the flooding algorithm and a model of efficiency in terms of network coverage. The models are validated against simulations. The results presented in this paper have significant implications for the standardization process.
