Traditional multiple access schemes, as well as more recent preamble-based schemes, cannot achieve the extremely low latency, complexity, and collision probability required by the next-generation Internet-of-Things (IoT) networks to operate. To addre

LoRaWAN networks rely heavily on the adaptive data rate algorithm to achieve good link reliability and to support the required density of end devices. However, to be effective the adaptive data rate algorithm needs to be tuned according to the level

In this article, we evaluate the performance of a LoRaWAN network in industrial scenarios where different Industrial Internet of Things (IIoT) end nodes communicate to a central controller in order to provide monitoring and sensing information to opt
