Performance Analysis of the Hybrid MQTT/UMA and Restful IoT Security Model

Internet of Things (IoT) environments are being deployed all over the globe. They have the potential to form solutions to applications, from small scale applications to national and international ones. Therefore, scalability, performance, and security form a triangle of requirements that must be carefully set. Furthermore, IoT applications require higher security standards. A previously proposed IoT application framework with a security embedded structure using the integration between message queue telemetry transport (MQTT) and user-managed access (UMA) is analyzed in this work. The performance analysis of the model is presented. Comparing the model with existing models and different design structures shows that the model presented in this work is promising for a functioning IoT design model with security. The results and analysis showed that the built-in security model had performed better than models with other frameworks, especially with fog implementation.
