This paper pointed out the benefits as well as the security risk that is the result of inconsistencies of software applications from different manufacturers and the lack of standards in IoT devices networks. Message Queue Telemetry Transport (MQTT) is now one of the most used open protocols in the Internet of Things. The term IoT is often followed by a great enthusiasm of researchers. End-users also share the same sentiment, ignoring the security risks that arise from dropping and reconnecting IoT devices that very often send passwords to server in plain text, while manufacturers often remain silently indifferent. They primary put focus on profitability, but not on safety. In other words, the door on smart homes remains wide open for hackers. This paper gives an overview of one potential solution of the Internet of Things security problem.

“…MQTT [12][13][14][15][16] uses a publish-subscribe model for IoT communication between devices, 12,[17][18][19] which reduces network traffic overall. In this model, the devices are not needed for connecting directly to other devices or repeating their requests.…”

Message queuing telemetry transport (MQTT) is an application layer protocol that enables effective device communication in the Internet of Things (IoT). MQTT operates according to a publish‐subscribe model, where a broker receives messages from the publishers and then forwards them to the subscribers. However, existing cloud‐based MQTT brokers lead to network bottlenecks due to the large number of devices that interact with them. Therefore, mist computing is involved, where the MQTT brokers are deployed closer to the IoT devices and the workload is distributed across multiple brokers. Nevertheless, the distributed mist‐based MQTT architecture introduces serious issues caused by the massive volume of flow exchanged by IoT devices. In this article, we introduce MQTT‐SD to address these issues. MQTT‐SD enhances MQTT protocol syntax with fusion semantic aggregation. It accomplishes MQTT topic fusion on the MQTT broker side with consideration of topics' distribution. We carried out extensive simulation and emulation to demonstrate MQTT‐SD efficacy. The results show that MQTT‐SD reduces MQTT flow and has the lowest traffic load compared to MQTT+ and MQTT‐MFA.

“…Для связи между устройствами IoT и сервером в проектируемой системе используется протокол MQTT (Message Queuing Telemetry Transport), позволяющий обмениваться сообщениями между устройствами по шаблону «издатель-подписчик» в условиях ограничения по пропускной способности канала. Особенности работы системы связи, построенной на MQTT и состоящей из сервера-издателя, сервера-брокера и одного или нескольких клиентов в прикладных исследованиях, могут быть почерпнуты, например, в [10]. В качестве сервера-брокера используется Mosquitto -свободно распространяемая реализация MQTT-брокера, которая обеспечивает надежную доставку сообщений между устройствами и сервером.…”

The article discusses the features of software and hardware complex development to monitor the efficiency of employees by means of an ESP8266 microcontroller and video cameras with a YOLOv8 neural network that meets the requirements of a 'smart shop'. The purpose of this study is to justify and evaluate the working concept of the created software and hardware complex in the form of a working prototype. Examples of current developments of similar monitoring systems realized within the paradigm of the Internet of Things, are given. However, the systems found in international practice focus on processing images of moving personnel only and do not analyze the technical parameters of the equipment this personnel work on. This study attempts to overcome this limitation. A schematic diagram of the system operation consisting of four key modules has been developed: a data collection module from machine-tools, an employee identification module, a primary data processing module, a web server with software application to manage the entire system in real time. The MQTT (Message Queuing Telemetry Transport) protocol is used for communication between devices and the server in the designed system to provide quality of data transmission under conditions of channel bandwidth limitations. Combined analysis of data from both machine-tools (control of the load of the electric motor) and the movement of workers in the space of the production room is proposed within the concept of developing such systems for the first time. Evaluation tests on the monitored data showed the operability of the entire complex, the problem of object automatic detection in the camera image flow and their location within the coordinate system of the production room was solved.
