MQTT Latency Evaluation in Cloud-Based Spectrometer Control
This paper investigates latency characteristics of MQTT communication in remote spectrometer control. A comparative study of AWS IoT Core and HiveMQ broker implementations across various Quality of Service levels has been presented. Methodologies include detailed measurements of control command and data feedback latencies, followed by statistical analysis. Initial findings have demonstrated a monotonic increase in latency and its variability (jitter) as QoS levels rise for both brokers, confirming the inherent MQTT trade-off between reliability and speed.
