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…
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…
Communication Aspects of the Integration of Wireless IoT Devices with Distributed Ledger Technology
Pietro Danzi, Anders E. Kalør, René B. Sørensen +4
The pervasive need to safely share and store information between devices calls for the replacement of centralized trust architectures with the decentralized ones. Distributed Ledge…
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…
Data Aggregation and Packet Bundling of Uplink Small Packets for Monitoring Applications in LTE
Dong Min Kim, René B. Sørensen, Kashif Mahmood +3
In cellular massive Machine-Type Communications (MTC), a device can transmit directly to the base station (BS) or through an aggregator (intermediate node). While direct device-BS…
