Design of a secure data transmission system in NB-IoT environment

Abstract

This work presents the design and implementation of a secure data transmission system for an IoT-based weather station using NB-IoT (Narrowband Internet of Things). The system integrates multiple sensors to measure environmental parameters such as temperature, humidity, atmospheric pressure, light intensity, precipitation, and air quality. A key focus is on ensuring energy-efficient, long-term operation in remote environments while maintaining data security through encryption and secure protocols. The proposed solution utilizes MQTT over NB-IoT for reliable data transmission, with results demonstrating efficient power management and stable connectivity.
