The Effect of TLS Encryption on MQTT Protocol Security and Performance in Meteorological-IoT Networks

The complex idea of the traditional internet is the Internet of Things (IoT). IoT allows everything in our lives to be connected to the internet or to one another so that data can be shared and certain tasks may be carried out via the network. In this study, MQTT with TLS is compared to non-TLS MQTT communication in meteorological IoT networks to examine its security and performance. In two scenarios—MQTT without TLS (using basic authentication) and MQTT with TLS (securing data transmission)—key parameters such connection establishment time, data overhead, energy efficiency, and attack resilience are assessed. The findings indicate that although TLS improves security by thwarting assaults, it also results in longer connection times, more data overhead, and higher energy usage. The trade-offs between security and performances are highlighted in this analysis, which offers guidance for improving MQTT-based communication in resource-constrained, real-time meteorological Internet of Things systems.
