Statistical Characterization and Prediction of E2E Latency over LEO Satellite Networks
Andreas Casparsen, Jonas Ellegaard Jakobsen, Jimmy Jessen Nielsen +2
Low Earth Orbit (LEO) satellite networks are emerging as an essential communication infrastructure, with standardized 5G-based non-terrestrial networks and their integration with t…
Experimental Study of Low-Latency Video Streaming in an ORAN Setup with Generative AI
Andreas Casparsen, Van-Phuc Bui, Shashi Raj Pandey +2
Current Adaptive Bit Rate (ABR) methods react to network congestion after it occurs, causing application layer buffering and latency spikes in live video streaming. We introduce a…
Near Real-Time Data-Driven Control of Virtual Reality Traffic in Open Radio Access Network
Andreas Casparsen, Beatriz Soret, Jimmy Jessen Nielsen +1
In mobile networks, Open Radio Access Network (ORAN) provides a framework for implementing network slicing that interacts with the resources at the lower layers. Both monitoring an…
Sustainable Wireless Services with UAV Swarms Tailored to Renewable Energy Sources
Igor Donevski, Marco Virgili, Nithin Babu +4
Unmanned Aerial Vehicle (UAV) swarms are often required in off-grid scenarios, such as disaster-struck, war-torn or rural areas, where the UAVs have no access to the power grid and…
Enabling On-Demand Cyber-Physical Control Applications with UAV Access Points
Igor Donevski, Jimmy Jessen Nielsen
Achieving cyber-physical control over a wireless channel requires satisfying both the timeliness of a single packet and preserving the latency reliability across several consecutiv…
Performance trade-offs in cyber-physical control applications with multi-connectivity
Igor Donevski, Israel Leyva Mayorga, Jimmy Jessen Nielsen +1
Modern communication devices are often equipped with multiple wireless communication interfaces with diverse characteristics. This enables exploiting a form of multi-connectivity k…
An Experimental Analysis on Drone-Mounted Access Points for Improved Latency-Reliability
Igor Donevski, Christian Raffelsberger, Micha Sende +2
The anticipated densification of contemporary communications infrastructure expects the use of drone small cells (DSCs). Thus, we experimentally evaluate the capability of providin…
Modelling and Experimental Validation for Battery Lifetime Estimation in NB-IoT and LTE-M
André Sørensen, Hua Wang, Maxime Jérôme Remy +5
Internet of Things (IoT) is one of the main features in 5G. Low-power wide-area networking (LPWAN) has attracted enormous research interests to enable large scale deployment of IoT…
Queuing with Deterministic Service Times and No Waiting Lines in Machine Type Communications
René Brandborg Sørensen, Jimmy Jessen Nielsen, Petar Popovski
The growth of Machine-Type Communication (MTC) increases the relevance of queuing scenarios with deterministic service times. In this letter, we present a model for queues without…
Machine Learning Methods for Monitoring of Quasi-Periodic Traffic in Massive IoT Networks
René Brandborg Sørensen, Jimmy Jessen Nielsen, Petar Popovski
One of the central problems in massive Internet of Things (IoT) deployments is the monitoring of the status of a massive number of links. The problem is aggravated by the irregular…
Analysis of LoRaWAN Uplink with Multiple Demodulating Paths and Capture Effect
René Brandborg Sørensen, Nasrin Razmi, Jimmy Jessen Nielsen +1
Low power wide area networks (LPWANs), such as the ones based on the LoRaWAN protocol, are seen as enablers of large number of IoT applications and services. In this work, we asses…
Analysis of Latency and MAC-layer Performance for Class A LoRaWAN
R. B. Sørensen, D. M. Kim, J. J. Nielsen +1
We propose analytical models that allow us to investigate the performance of long range wide area network (LoRaWAN) uplink in terms of latency, collision rate, and throughput under…
Secure Real-Time Monitoring and Management of Smart Distribution Grid using Shared Cellular Networks
Jimmy J. Nielsen, Hervé Ganem, Ljupco Jorguseski +9
The electricity production and distribution is facing two major changes. First, the production is shifting from classical energy sources such as coal and nuclear power towards rene…
Location-Quality-aware Policy Optimisation for Relay Selection in Mobile Networks
Jimmy J. Nielsen, Rasmus L. Olsen, Tatiana K. Madsen +2
Relaying can improve the coverage and performance of wireless access networks. In presence of a localisation system at the mobile nodes, the use of such location estimates for rela…
