Focusing on a mobile sensing framework at NITOS facility we developed a sophisticated framework with tolerant delay characteristics. The overall framework consists of two main parts, the NITOS mobile sensing device and the Road Side Units (RSUs). The NITOS mobile devices are mounted on vehicles and collect measurements as the vehicles move around in a city. The acquired data are locally stored at the device, until a vehicle is found into the range of any RSU. RSUs are statically deployed gateways that are connected to a backbone network, aiming to provide wireless connection for data forwarding. When a NITOS mobile device, detects the existence of a RSU, attempts to establish a wireless connection, in order to upload the measurements to a specic Server. The Server stores the transfered data and provides them for further analysis and visualization.

The aforementioned platform features:
