Internet of Things (IoT) is a rapidly developing technology that has made great achievements in smart cities, smart agriculture, and smart medical care in recent years [1]
This paper proposes an adaptive link-level recovery mechanism based on link adjustment for Long Range Radio Wide Area Network (LoRaWAN)
When a communication link fails, multiple candidate links are selected based on Quality of Service (QoS) requirements, the distribution of LoRaWAN gateways and repeaters
Summary
IoT is a rapidly developing technology that has made great achievements in smart cities, smart agriculture, and smart medical care in recent years [1]. Communication between terminals and LoRa gateways can be transmitted through different channels and coding rates. LoRaWAN provides a scheme called Adaptive Data Rate (ADR), which is used to control the transmission parameter settings of the uplink from terminals and LoRa gateway [5]. In order to solve the above problems, an adaptive mechanism for link failure recovery is proposed in this paper. We propose an adaptive link-level recovery mechanism from the perspective of fault tolerance. This mechanism with repeaters as backup links aims to eliminate critical nodes and ensure network load balancing.
