5G NB-IoT via low density LEO Constellations
René Brandborg Sørensen, Henrik Krogh Møller, Per Koch
5G NB-IoT is seen as a key technology for providing truly ubiquitous, global 5G coverage (1.000.000 devices/km2) for machine type communications in the internet of things. A non-te…
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…
