Edge Computing – an emerging research field
Edge computing is one of the drivers for future industries and a fundamental component in 5G networks, says Professor Javid Taheri. He has recently published a reference book on the subject, Edge Intelligence: From Theory to Practice. The book provides a valuable introduction to a nascent field of research.
What are the current shortcomings of cloud computing systems that Edge Computing solves?
Karlstad University starts a new master's program
Karlstad University receives grant of 2 million SEK from the Knowledge Foundation to develop a high in-demand Master’s programme in data-driven mechanical engineering.
- There is an increasing demand for this type of programme, says Anton Tkachuk, Lecturer in Mechanical Engineering and project manager in the development of the Master’s programme. The challenge is to create a degree programme that addresses areas such as data-driven approach and digitalisation tools.
Edge computing optimizes services for smart maintenance and remote support
The DRIVE sub-project 3 “Service optimization in federated edge platforms“ aims to design and develop artificial intelligence and machine learning based solutions to optimize the performance of augmented reality and virtual reality services on user-edge-cloud continuum platforms. With this in place, smart maintenance techniques providing remote service and assistance could run more smoothly.
Edge computing is the next generation of computing platforms to bring computing to where the data is created or required processing, instead of at its core, as is the case with cloud computing. Less network bandwidth is then being used, and the communication latency will be much lower, and significantly improve the performance of the desired service.
The antenna takes research on the conditions for information transfer to new heights
Karlstad University has research equipment in several places in its premises. Now it could also be found outdoors. Since February, a Starlink antenna has been installed on the roof of the building where the Computer Science researchers are located. The antenna can now be used to measure the performance of satellite internet connections, a welcome addition to ongoing measurements of 5G and Wi-Fi network performance.
- Our research is about information transfer, sending data over the internet, says Stefan Alfredsson, senior lecturer in Computer Science. There are different ways to connect to the internet, such as via mobile networks, Wi-Fi, 5G or satellite systems. The antenna we installed on the roof is part of the Starlink satellite system. We measure the bandwidth, latency and reliability of the Starlink connection and compare how well it works with other connection options.
Train connectivity tests on aggregated connectivity resulted in a Best Paper
How reliable are different methods for connecting to mobile networks to support train signaling systems? This is what Professor Anna Brunström and Associate Professor Johan Garcia at Karlstad University have investigated in collaboration with DRIVE partner Icomera. Their work was recently highlighted in the trade press and has previously been rewarded with a Best Paper award at the IEEE 36th International Workshop on Communications Quality and Reliability (CQR) in Virginia, USA, for the paper "Measuring and Modeling Aggregate LTE Connection Reliability for Train Operators".
Tests were conducted on 50 train sets operating on the Malmö-Stockholm route during the 2019-2021 time period. The assumption was that aggregated connectivity, i.e. multiple simultaneous connections, increases reliability and provides a more stable support for connectivity.
Real life 5G network measurements in Rome
As part of the DRIVE project, real life measurements of 5G networks are now taking place in Rome, Italy, where two large mobile operators are up to proof in terms of coverage, connectivity, latency and throughput performance.
In Dec. 2020 - Jan. 2021, a large-scale measurement campaign took place in major parts of Rome, Italy, to analyze the ongoing evolution of the mobile cellular ecosystem and the initial rollout of 5G Non-Standalone operational networks.
