Wireless Mesh Networks (WMNs) are self-organising ad-hoc networks that support broadband communication. Due to changes in the topology, route discovery and maintenance play a crucial role in the reliability and the performance of such networks. Formal analysis of WMNs using exhaustive model checking techniques is often not feasible: network size (up to hundreds of nodes) and topology changes yield state-space explosion. Statistical Model Checking, however, can overcome this problem and allows a quantitative analysis.
In this paper we illustrate this by a careful analysis of the Ad hoc On-demand Distance Vector (AODV) protocol. We show that some optional features of AODV are not useful, and that AODV shows unexpected behaviour—yielding a high probability of route discovery failure.
