Today’s post is about the just finished master project lecture about smart cities at Universität Hamburg. The project’s goal was the prototypical implementation of a navigation solution for wheelchair users. For this purpose, a suitable route was selected with a wheelchair-friendly surface. The data required for navigation is automatically collected by a sensor box that can be attached to wheelchairs. This data is exchanged from wheelchair user to wheelchair user with the help of drasyl.

This post presents another use case of drasyl: During an eight-day block course at the university, a total of five student groups designed and prototyped key-value stores. In the process, drasyl was used for communication so that the students could fully concentrate on implementing the business logic of the key-value store.

Today’s post is about the master thesis “A Secure Context-Aware Middleware for Computation Offloading in Untrustworthy, Open, and Dynamic Edge Environments” by Kevin Röbert. In his master’s thesis, Kevin Röbert designed, implemented, and evaluated a system capable of offloading computations to the cloud, grid, and edge devices. He integrated drasyl into the Tasklet computation offloading middleware.

We’re happy to announce that our paper “Accessing Smart City Services in Untrustworthy Environments via Decentralized Privacy-Preserving Overlay Networks” has been published in the proceedings of the 2021 IEEE International Conference on Service-Oriented System Engineering (SOSE)". Within this paper, we presented how our approach can be used to provide the foundations for a network of Smart City Services.

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.

Today’s paper is about a master thesis that deals with in-network data processing systems. Maintaining data integrity in in-network data processing systems is difficult. While individual nodes can be assumed to cooperate in closed systems, malicious participants must be detected and dealt with in open networks.

Today we would like to present you another use case of drasyl: A colleague of ours developed a distributed data structure based on the SkipNet presented by Microsoft. In addition to that, he added capabilities to store multi-attributed data on a SkipNet.
