Beyond the Star of Stars: An Introduction to Multihop and Mesh for LoRa and LoRaWAN

LoRa has emerged in recent years as a wireless technology providing long-range communication for low-power Internet-of-Things (IoT) devices. The LoRaWAN architecture adds the medium access control (MAC) and application layers, defines star of stars topology suitable many diverse IoT applications. However, number scenarios, more flexible network than LoRaWAN’s is needed. We review state art design implementation multihop mesh solutions LoRaWAN. discuss remaining challenges to overcome order unlock opportunities that decentralized, self-organizing, infrastructure-less networks can bring
