Assessment of Urban-Scale Wireless Networks With a Small Number of Measurements

Category: Software and Web Development, Networking and Communications

Overview In order to evaluate, improve, or expand a deployed, citywide wireless mesh network, it is necessary to assess the network's spatial performance. This paper presents a general framework to accurately predict a network's well-served area, termed the metric region, via a small number of measurements. Assessment of deployed networks must address two key issues: non-uniform physical-layer propagation and high spatial variance in performance. Addressing non-uniformity, one's framework estimates a mesh node's metric region via a data-driven sectorization of the region. The author finds each sector's boundary (radius) with a two-stage process of estimation and then measurement-driven "Push-pull" refinement of the estimated boundary.
