MQ Telemetry Transport (MQTT) has been designed and developed for an ultra-low bandwidth communication and has been applied to used in Internet of Things (IoT). Recently, MQTT has been used in traditional TCP/IP networks. Yet, the ultra-low bandwidth and long-range communication of MQTT have been considerably increased. Previous proposed techniques still struggle to make MQTT compatible with Long-Range (LoRa) networks. In this paper, we have design and implement the Telemetry Media Access Control (TMAC). Our TMAC helps increase ranges of MQTT's data communications. We have experimented our TMAC using a network testbed. Experimental results have illustrated that our TMAC can transfer data over 5 kilometers with low network overhead. [ABSTRACT FROM AUTHOR]
