  Low Power Wide Area Networks (LPWAN) are wireless connectivity solutions for
Internet-of-Things (IoT) applications, including industrial automation. Among
the several LPWAN technologies, LoRaWAN has been extensively addressed by the
research community and the industry. However, the reliability and scalability
of LoRaWAN are still uncertain. One of the techniques to increase the
reliability of LoRaWAN is message replication, which exploits time diversity.
This paper proposes a novel hybrid coded message replication scheme that
interleaves simple repetition and a recently proposed coded replication method.
We analyze the optimization of the proposed scheme under minimum reliability
requirements and show that it enhances the network performance without
requiring additional transmit power compared to the competing replication
techniques.
