Abstract Internet-of-Things (IoT) applications at the city scale require a reliable and energy-efficient messaging service. In order to save energy consumption at each embedded IoT instrument, thus to prolong the application lifetime, it is best that the service be free of redundant messages. In this paper, we analyze the MQTT messaging protocol and show that there are three problems that may either cause message losses or produce redundant messages. For each problem we propose a solution, and we show that our design as a whole may be implemented efficiently. We have been implementing the design, and it is our hope that the messaging protocol as a result would be a good support to many smart-city applications. © 2021 Owner/Author. © 2021 ACM.
