Extending Internet Access Over LoRa for Internet of Things and Critical Applications (2501.03465v3)

Abstract: LoRa bridges the gap between remote locations and mainstream networks, enabling large-scale Internet of Things (IoT) deployments. Despite the recent advancements around LoRa, Internet access over this technology is still largely unexplored. Most existing solutions only handle packets within the local LoRa network and do not interact with web applications. This limits the scalability and the ability to deliver essential web services in disconnected regions. This work proposes and implements ILoRa to extend the public Internet to disconnected areas for essential service delivery. ILoRa enables accessing Application Programming Interfaces (APIs) and web pages on the Internet over a LoRa backbone network. It comprises a ILoRa coordinator code (ICN) and access point nodes (APNs). The ICN interfaces the LoRa network with the public Internet and interprets content. The APN tethers a WiFi hotspot to which devices connect and access the web content. This work further proposes data handling methods for ICNs and APNs. An actual hardware-based implementation validates the proposed system. The implementation achieves a throughput of 1.06 kbps tested for an Internet-based API returning JSON data of 930 B. Furthermore, the APN consumed approximately $0.162$A current, and the resource utilization on the ICN was minimal.
