Round robin MQTT-based routing algorithm for agricultural IoT network: communication optimization between sensors, actuators and brokers

This paper proposes a new protocol based on MQTT for IoT networks in the agricultural domain named FNMB. The latter constitutes a good means of communication between publishers, subscribers and brokers and improves the transfer of agricultural data and allows a good balance of the load between brokers using the principle of the round-robin technique. By alternating between brokers the roles of central broker and bridge broker, our approach allows the network to operate smoothly and reliably. This article also explores the advantages of our approach compared to traditional IoT systems with a single broker, or with a fixed central broker in the case of multiple brokers, based on criteria such as energy consumption and load balancing, and shows the promising results obtained with our approach.
