  8. Scenario Elements District Concentrator • District Concentrator (DC) • Equipped with W M-BUS, Wi-Fi, 5G and Zigbee • Building Concentrator (BC) • Equipped with W M-BUS, Wi-Fi and Zigbee • Bus • Equipped with Wi-Fi and Zigbee • Car (driver) • Equipped with Wi-Fi and 5G • People • Equipped with Wi-Fi and 5G

  9. DTN • Smart Building Each building is equipped with smart devices in order to monitor the consumptions in terms of gas / electricity / water. A Building Concentrator (BC) gathers data from devices in the building and then it has to send them to the District Concentrator (DC). A point-to-point connection between the BC and the DC will be present through wireless M-BUS at 169 MHz, however being the density of DCs much lower than the density of BCs, an alternative link will be created by exploiting the presence of objects moving in the city (DTN paradigm). • Objects • Buses, Cars and People may act as mules, to help BCs to reach one DC
