Anti-fragile ICT Systems

By Kjell Jørgen Hole

Springer and Simula have launched a new book series, Simula SpringerBriefs on Computing, which aims to provide introductions to select research areas in computing. The series presents both a state-of-the-art disciplinary overview and raises essential critical questions in the field.

Wideband RF over IP Demonstrator (WROI)

The project will explore advanced compression techniques of high bandwidth analogue signals for this scenario. The focus is to design and implement a bidirectional wideband RF over IP module with the target to support bandwidths up to 5 GHz. The targeted use-case scenarios are bi-directional VSAT communication and downlink from earth observation satellites. A main challenge in the project is the design and implementation of efficient compression algorithms of high bandwidth analogue signals, like Rice-Golomb coding and more advanced compressed sensing techniques like Xampling.

Air interface development for ultra-low powered Internet of Things satellite applications (ALISA)

A satellite network is the only cost efficient technology to collect data from, and control, remote sensors and other IoT devices, in order to protect and learn about resources all over the arctic land and ocean areas.  For example, such a network may provide low latency low data rate for underwater gliders that can cover large distances efficiently and occasionally surfaces to dump data and receive commands, or medium data rate communication for surface buoys that provide situational awareness both above and below the water. The main objective of the ALISA project is to design, develop and demonstrate frequency agnostic air interface for low power IoT messaging on the C/X, Ku, and Ka-bands for use on LEO, (MEO), HEO and (GEO) satellites. The project is a collaboration between Widenorth, Space Norway (Norsk Romsenter), NTNU, and Simula UiB. The role of Simula UiB is to design the error correcting codes for the air interface, and the security part of the communication system.
