Considerable research has focused on the design of routing protocols for wireless multi-hop networks. Yet, very little is understood about the stability of routes in such networks. This understanding is important in the design of wireless routing protocols, and in network planning and management. This paper presents results from the measurement-based characterization of routing stability in two network deployments, the UCSB MeshNet and the MIT Roofnet. To conduct these case studies, it collected detailed link quality information over several days from each of these networks. Using this information, the paper investigated routing stability in terms of route-level characteristics, such as prevalence, persistence and flapping.
