Designing a Method of Data Transfer Using Dual Message Queue Brokers in an IoT Environment

As the number of IoT devices rapidly increases, research is actively conducted to manage data transmitted from a large number of devices. Various services such as monitoring service requesting IoT sensor data and real-time analysis processing service are increasing. However, each device is connected to different services, making expansion difficult. In order to solve this problem, Message Queue collects the data processing performed by the various services in one place and distributes the work to necessary services by placing a message broker. AMQP is an open standard protocol for message-oriented middleware. It is defined to enable message exchange between different processes or programs. Recently, various services are being provided not only in servers but also in gateways, and message transmission processing is required. In this paper, we propose a method for stable and flexible data delivery by deploying Broker supporting AMQP in gateways and servers in IoT environments where various devices exist.
