Abstract
IoT technologies currently operate as independent silos, and roaming is possible only if there are prior interconnection agreements. To our knowledge, there are no standardised procedures for interconnecting different IoT networks for roaming. The focus of IoTRoam is to set up an operational roaming model that scales, seamlessly works with existing IoT infrastructures and interconnects on a global basis with minimum initial configuration requirements. As a Proof-of-Concept, we designed, implemented and tested a roaming LoRaWAN architecture using time-tested infrastructures on the Internet such as PKI and the DNS. The IoTRoam experience helped us to propose changes to the LoRaWAN Backend Interface Specification that have since been accepted. We also evaluated whether the proposed mechanisms satisfy constrained IoT requirements.
The article “IoTRoam: design and implementation of an open LoRaWAN roaming architecture” discusses efforts to enhance roaming in LoRaWAN networks.
Traditional roaming infrastructures are often confined to their specific IoT technologies or applications. IoTRoam aims to establish an operational roaming system that’s easily deployable today, evolves seamlessly, integrates with existing IoT infrastructures with minimal adaptations, requires minimal initial configuration, and operates globally.
The project began by focusing on LoRaWAN, intending to extend to other IoT technologies. An experimental platform based on LoRaWAN was designed, implemented, and tested, using established infrastructures like PKI and DNS.
IoTRoam has led to updates in LoRaWAN backend specifications and operational problem solutions, also assessing whether the proposed mechanisms meet stringent IoT requirements.
