Toward a Security IoT Platform with High Rate Transmission and Low Energy Consumption

The Internet of Things currently is one of the most interesting technology trends. Devices in the IoT network towards mobility and compact in size, so these have a rather weak hardware configuration. One of the essential concern is energy consumption. There are many lightweights, tailor-made protocols for limited processing power and low energy consumption, of which MQTT is the typical protocol. A light and simple protocol like MQTT, however, has many problems such as security risks, reliability in transmission and reception. The current MQTT protocol supports three types of quality-of-service (QoS). The user has to trade-off between the security/privacy of the packet and the system-wide performance (e.g., transmission rate, transmission bandwidth, and energy consumption). In this paper, we present an IoT Platform Proposal to improve the security issues of the MQTT protocol and optimise the communication speed, power consumption, and transmission bandwidth, but this still responds to reliability when transmitting. We also present the effectiveness of our approach by building a prototype system. Besides, we compare our proposal with other related work as well as provide the complete code solution is publicized to engage further reproducibility and improvement.
