Johannes Hofer received his Diploma degree (Dipl.-Ing.) in Electrical Engineering from the Dresden University of Technology in 2022. As part of his studies, he completed an internship at National Instruments, focusing on near-field characterization of antenna arrays. His student research focused on the evaluation of the NetFPGA platform for network testing. His diploma thesis investigated the offloading of Simultaneous Localization and Mapping (SLAM) processes to the edge cloud, which laid the foundation for his subsequent research as a PhD student at the Deutsche Telekom Chair of Communication Networks in 2022.

abstract = {Edge-assisted Visual Simultaneous Localization and Mapping (V-SLAM) systems
offload complex analysis modules from computationally constrained mobile
devices to cloud servers at the network edge. As visual data must travel
through networks to reach the edge cloud, it is crucial to minimize
transferred data while maintaining reliable and accurate localization and
map generation. State-of-the-art systems perform pre-analysis of SLAM
modules on the mobile device, causing high processing delays and limiting
functionality. To minimise both throughput demand and latency, we are
investigating video compression techniques in Analyze-Then-Compress (ATC)
transmission systems. Evaluations employing the widely used H.264
demonstrate that CTA achieves lower throughputs than its counterparts, as
well as significantly reduced processing delays and transmission latencies.
The results open up new possibilities to explore this research direction on
edge-assisted V-SLAM further.},
