Hyperuniformity, which is a type of order that is characterized by the suppression of long-range density fluctuations in comparison to the fluctuations in standard disordered systems, has emerged as a powerful concept in many natural and engineered phenomena. In this paper, we harness hyperuniform point patterns to generate disordered, spatially-embedded networks that are distinct from both perfectly ordered lattices and uniformly random spatial networks. We refer to this class of disordered networks as \emph{hyperuniform-point-pattern-induced (HuPPI) networks}, and we compare them to counterpart \emph{Poisson-point-pattern-induced (PoPPI) networks} and networks that we generate from random-sequential-adsorption (RSA) packings (which have local order but are not hyperuniform). We examine HuPPI, PoPPI, and RSA networks that we generate using Gabriel, Delaunay, Delaunay-centroidal, and Voronoi network-generation methods. We show that HuPPI networks have smaller mean normalized total effective resistances (TERs) than PoPPI networks in Gabriel, Delaunay-centroidal, and Voronoi networks and have shorter mean random-walk mixing times than PoPPI networks in Gabriel, Delaunay, and Delaunay-centroidal networks. For all four network-generation methods and for both HuPPI and PoPPI networks, we find that the Ollivier--Ricci curvature (ORC) of an edge is negatively correlated with its TER edge contribution (i.e., the increase in TER that results from removing that edge). Collectively, our results (1) illustrate how the local network geometry that ORC measures is related to transport and network connectivity and (2) demonstrate that the network-generation method provides an additional design lever for spatial networks beyond the choice of their underlying point pattern.
