Analysis of the OLSR Protocol by Using Formal Passive Testing

In this paper we apply a passive testing methodology to the analysis of a non-trivial system. In our framework, so-called invariants provide us with a formal representation of the requirements of the system. In order to precisely express new properties in multi-node environments, in this paper we introduce a new kind of invariants. We apply the resulting framework to perform a complete study of a MANET routing protocol: The optimized link state routing protocol.
