Abstract The Internet of Things (IoT) has enabled various intelligent services, and IoT
service range has been steadily extended through long range wide area communication
technologies, which enable very long distance wireless data transmission. End-nodes are
connected to a gateway with a single hop. They consume very low-power, using very low
data rate to deliver data. Since long transmission time is consequently needed for each
data packet transmission in long range wide area networks, data transmission should be
efficiently performed. Therefore, this paper proposes a multicast uplink data transmission
mechanism particularly for bad network conditions. Transmission delay will be increased
