Multinode LoRa-MQTT of Design Architecture and Analyze Performance for Dual Protocol Network IoT

Abstract

LoRaWAN networks and large places do not support Wi-Fi for multiple points. An architecture that offers dual networks to alter their supporting networks is needed for IoT device installation. The novelty in this research is that designing an architecture for multimode LoRa-MQTT with a mechanism for testing LoRa data transmission with different delays and Wireshark for testing Wi-Fi network QoS on MQTT is necessary. This hour-long LoRa network experiment shows that the End-Node can only receive one data at a time. One data set will be received if several data sets are obtained due to conflict. The second experiment showed data barely reached 70%. The signal strength or RSSI, and the node that sent the data initially decide the data received from a given node, some seconds apart, towards tested QOS with excellent packet loss, 21 ms delay, 50, 616 bytes/s throughput, and 0.1426 jitter. Avoid data conflicts and loss by utilizing fewer nodes or adding end nodes in this experiment. The network service is excellent. According to this study, LoRa and MQTT can work well together. This approach could solve Internet of Things communication concerns, especially in large places that are LoRaWAN-inaccessible and Wi-Fi networks are limited.
