Today we are talking about another use case for drasyl: SANE. This use case is special for us because it finally made us decide to develop drasyl. The SANE project is now finished; therefore, we would like to present the project’s results.

As a final step of the project, we had the pleasure to present our project results in the form of the demo paper “Smart Urban Data Space for Citizen Science” at this year’s Conference on Networked Systems (NetSys 2021).


In smart cities, the number of citizen-operated sensor devices continues to increase. This development multiplies the amount of collectible data about our urban environment. Currently, many of those sensors are connected to proprietary cloud services with questionable effects on user privacy. Simply avoiding interconnecting those devices misses out on opportunities to collectively use data as a shared source of information. The city of Hamburg sponsored project Smart Networks for Urban Citizen Participation (SANE) aims at enabling citizens to connect existing sensors to create a city-wide data space while keeping control of devices and gathered data. Interconnecting these sensors enables all citizens to generate higher value information and thus improve their urban environmental awareness. In this paper, we describe the demo of our SANE architecture. The demo presents how citizens connect to the city-wide data space, how data can be collected, processed, and shared in a privately manner.

The paper can be accessed through ECEASST:

Initially, it was planned to present our demo in person. However, due to the pandemic, we had to record a video. You can find the video on the following website:
