LoRaWAN Mathematical Modeling and Optimization

The Internet of Things (IoT) is gaining popularity every year. According to IoT statistics, the number of IoT devices was over 10 billion in 2021, and by 2030 the number of such devices is expected to more than double. This rapid growth of the Internet of Things has led to the development of low-power wireless technologies, in particular, Low-Power Wide-Area network (LPWAN) technologies. One of the most popular and worldwide known LPWAN technologies is LoRaWAN.

WNL has conducted extensive research, to identify the weak spots of LoRaWAN protocols and ways to mitigate them. WNL developed multiple modeling approaches for LoRaWAN networks, which were then used to propose and evaluate new algorithms for MCS selection and end-device operation modes in various scenarios.
