The study, involved collecting multi-modal data, e.g., through continuous gathering of SNMP logs, syslogs, passive traffic capture, and limited active measurements in different parts of the city. The study is split into four components planning and deployment of the mesh, success of mesh routing techniques, likely experience of users, and characterization of how the mesh is utilized.
