Abstract
This work evaluates uplink scalability of industrial wireless networks regarding central- ity concepts. It applies simulations of centralized mesh-topology networks, taking WirelessHART networks as case study, in scenarios of high node density and varied quantities and distribution of access points. Performance criteria such as refresh rates, node buffer size and reliability are evaluated as varied project specifications. The study infers that the lowest end-to-end communication success rates are concentrated on chains which top nodes present higher degree and betweeness centrality, and the most faulty packages tend to be those generated on devices with lower proximity centrality.
