Seminar : Scalability Through Cooperation: A Distributed Federation in LoRaWAN Space

ow-Power Wide Area Networks (LPWAN) play a key role in the IoT marketplace wherein LoRaWAN is considered a leading solution. Despite the traction of LoRaWAN, research shows that the current contention management mechanisms of LoRaWAN do not scale. We address contention on LoRaWAN by introducing FLIP, a fully distributed and open architecture for LoRaWAN that fundamentally rethinks how LoRa gateways should be managed and coordinated. FLIP transforms LoRa gateways into a federated network that provides inherent support for roaming while tackling contention using consensus-driven load balancing. FLIP offers identical security guarantees to LoRaWAN, is compatible with existing gateway hardware and requires no updates to end-device hardware or firmware. These features ensure the practicality of FLIP and provide a path to its adoption. FLIP delivers scalable roaming and improved contention management in comparison to LoRaWAN.
These benefits are achieved within the resource constraints of cheap conventional LoRa gateways and requires no server hardware, allowing anyone to participate and benefit from it at a low-entry price.
