In one embodiment, a computing system may identify, in a geographic region, a number of sites satisfying one or more criteria based at least on geographic data accessed from one or more data sources. The system may generate, for the geographic region, a number of communication network graphs each satisfying one or more network coverage conditions. Each communication network graph may include a number of nodes corresponding to the sites and a number of edges corresponding to communication network connections between the sites. The system may rank the communication network graphs based on one or more performance parameters. The system may select an optimized communication network graph for the geographic region from the communication network graphs based on their respective rankings.
