Research and Design of a Decentralized Edge-Computing-Assisted LoRa Gateway

As a narrowband communication technology, long-range (LoRa) contributes to the long development of Internet Things (IoT) applications. The LoRa gateway plays an important role in IoT transport layer, and security efficiency are key issues current research. In centralized working model systems built by traditional gateways, all data generated reported end devices processed stored cloud servers, which susceptible such as loss falsification. Edge computing (EC), innovative approach that brings processing storage closer endpoints, can create decentralized infrastructure for systems, resulting EC-assisted model. Although this paradigm delivers unique features improved quality service (QoS), installing applications at gateways with limited memory capabilities presents considerable obstacles. This article proposes design implementation “EC-assisted gateway” using edge computing. Our proposed latency-aware algorithm (LAA) greatly improve reliability network system distributed technology achieve maintenance operations, detection, repair, replacement failures nodes network. Then, prototype was developed on embedded hardware system. Finally, experiments were conducted evaluate performance gateway. Compared conventional gateway, intelligent had 41.1% lower bandwidth utilization handled more devices, ensuring availability effectively.
