In the UrbanSense platform developed in the Future Cities Project, sensing devices based on the open-source Raspberry Pi platform were sparsely distributed across the city to measure environmental parameters. The data gathered by the sensors needs to be transferred to the cloud, preferably taking advantage of the existent local infrastructures. This work presents a proof-of-concept of a system that will use Porto’s vehicular network, composed by over 600 vehicles, to transfer sensor samples from the sensing devices of the UrbanSense platform to a cloud server, in a Delay Tolerant Networking (DTN) fashion. During the demo, we will show data being collected by a moving vehicle and later delivered to a server in the cloud.
