This paper proposes the time filter function to the MQTT protocol, which is a message based network protocol widely used in the Internet of Things, and presents an analysis and modification of the Mosquitto broker. Generally, message publishers send sensor values periodically to the MQTT broker, regardless of the capability of subscribers to receive them. Therefore, subscribers unilaterally receive messages even when they do not have enough memory to save them, resulting in lost messages. The time filter is a function that stops the MQTT broker from sending messages within a time period designated by a subscriber. In this paper, we modified Mosquitto, the open source MQTT broker, to add a time filter function and verified the effect of the time filter function through experiments. The experimental results showed that the time filter function significantly lowered the network load of the Mosquitto broker.
